Characterization of calcium lactate prepared from butter clam Saxidomus purpuratus shell powder was written by Yoon, In Seoung;Lee, Gyoon-Woo;Lee, hYun Ji;Park, Sung Hwan;Park, Sun Young;Lee, Su Gwang;Kim, Jin-Soo;Heu, Min Soo. And the article was included in Hanguk Susan Kwahak Hoeji in 2016.Application In Synthesis of Calcium 2-hydroxypropanoate pentahydrate This article mentions the following:

To facilitate the effective use of butter clam shell as a natural calcium resource, we determined the optimal conditions for calcium lactate (BCCL) preparation with high solubility using response surface methodol. (RSM). The polynomial models developed by RSM for pH, solubility and yield were highly effective in describing the relationships between factors (P<0.05). Increased molar ratios of calcined powder (BCCP) from butter clam shell led to reduced solubility, yield, color values and overall quality. The critical values of multiple response optimization to independent variables were 1.75 M and 0.94 M for lactic acid and BCCP, resp. The actual values (pH 7.23, 97.42% for solubility and 423.22% for yield) under optimization conditions were similar to the predicted values. White indexes of BCCLs were in the range of 86.70-90.86. Therefore, organic acid treatment improved color value. The buffering capacity of BCCLs was strong, at pH 2.82 to 3.80, upon the addition of less than 2 mL of 1 N HCl. The calcium content and solubility of BCCLs were 6.2-16.7 g/100 g and 93.6-98.5%, resp. Fourier transform anal. of IR spectroscopy data identified BCCL as calcium lactate pentahydrate, and the anal. of microstructure by field emission SEM revealed an irregular form. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5Application In Synthesis of Calcium 2-hydroxypropanoate pentahydrate).

Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Application In Synthesis of Calcium 2-hydroxypropanoate pentahydrate

Impact of gastric pH and dietary fiber on calcium availability of various calcium salts was written by Weerapol, Yotsanan;Cheewatanakornkool, Kamonrak;Sriamornsak, Pornsak. And the article was included in Silpakorn University Science and Technology Journal in 2010.Related Products of 5743-47-5 This article mentions the following:

The objective of this study was to compare calcium release and ionization from com. calcium supplements and various salts of calcium with different solubilities. The impact of pH of test fluid and dietary fiber co-administered with calcium supplement on calcium availability was also studied. Compressed tablets of six different calcium salts were prepared by direct compression. Calcium release from tablets was tested in simulated gastric fluid without pepsin (SGF, pH 1.2) or fed state simulated gastric fluid (FSSGF, pH 4.8), using USP dissolution apparatus The ionized calcium concentration in test fluid was determined by calcium ion selective electrode. The results demonstrated that most of the formulations released calcium within 1 h. Tablets made of higher solubility calcium salts demonstrated a faster calcium release. The calcium release from calcium hydrogen phosphate and calcium carbonate tablets in gastric fluid with higher pH showed a slower calcium release than in SGF. The dietary fiber co-administered with calcium supplement influenced the calcium availability, especially in medium with higher pH. The results suggested that most of the calcium salts could be used as calcium supplement. However, the use of calcium carbonate required an acidic environment in order to be dissolved in the gastrointestinal tract. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5Related Products of 5743-47-5).

Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Related Products of 5743-47-5

This study aimed to enhance the water solubility of calcium from tuna (Katsuwonus pelamis) bones (TB). Calcium hydroxyapatite (HA) was obtained by calcination of TB. For mineral profiles of TB and HA, Ca had the highest content followed by P with Ca/P of 3.47 and 1.94. Mg, K, and Na as macro minerals and Cr, Cu, Mn, and Zn as micro minerals were also found. Subsequently, HCl was applied to form structured HA-chloride compound (HA-Cl) then reacted with alk. to obtain structured HA-hydroxide compound (HA-OH). In order to enhance the water solubility, citric and lactic acid were individually reacted with HA-Cl and HA-OH to obtain structured HA-citrate compounds (HA-Cl-Ci and HA-OH-Ci) and structured HA-lactate compounds (HA-Cl-Lac and HA-OH-Lac). HA-Cl-Ci had the highest water solubility (93.34 卤 0.45%) followed by HA-OH-Lac (90.35 卤 0.23%) with Ca/P ratio of 2.28 and 2.24, resp. HA-Cl-Ci and HA-OH-Lac demonstrated the similar mineral profiles to those of HA but with different contents. The results of FT-IR indicated the carboxyl group of acid played an important role in binding Ca²⁺.

Bacteria incorporated with calcium lactate pentahydrate to improve the mortar properties and self-healing occurrence was written by Chaerun, Siti Khodijah;Syarif, Ridwan;Wattimena, Ridho Kresna. And the article was included in Scientific Reports in 2020.Synthetic Route of C6H20CaO11 This article mentions the following:

Concrete can be harmful to the environment due to its high energy consumption and CO₂ emission and also has a potential crack formation, which can promote a drop in its strength. Therefore, concrete is considered as a non-sustainable material. The mechanisms by which bacterial oxidation of organic carbon can precipitate calcite that may fill the voids and cracks on cement-based materials have been extensively investigated to prevent and heal the micro-cracks formation. Hence, this study focused on utilizing a new alkaliphilic bacterial strain indigenous to an Indonesian site, Lysinibacillus sphaericus strain SKC/VA-1, incorporated with calcium lactate pentahydrate, as a low-cost calcium source, with various bacterial inoculum concentrations The bacterium was employed in this study due to its ability to adapt to basic pH, thus improving the phys. properties and rejuvenating the micro-cracks. Exptl., the addition of calcium lactate pentahydrate slightly affected the mortar properties. Likewise, bacteria-incorporated mortar exhibited an enhancement in the phys. properties of mortar. The highest improvement of mech. properties (an increase of 45% and 36% for compressive and indirect tensile strength, resp.) was achieved by the addition of calcium lactate pentahydrate incorporated with 10% volume/volume bacterial inoculum [about 7 × 107 CFU/mL (colony-forming unit/mL)]. The self-healing took place more rapidly on bacterial mortar supplemented with calcium lactate pentahydrate than on the control specimen. XRD anal. demonstrated that the mineralogical composition of self-healing precipitates was primarily dominated by calcite (CaCO₃), indicating the capacity of L. sphaericus strain SKC/VA-1 to precipitate calcite through organic carbon oxidation for self-healing the artificial crack on the mortar. To our knowledge, this is the first report on the potential utilization of the bacterium L. sphaericus incorporated with calcium lactate pentahydrate to increase the mortar properties, including its self-healing ability. However, further study with the water-cement ratio variation is required to investigate the possibility of using L. sphaericus and calcium lactate pentahydrate as an alternative method rather than reducing the water-cement ratio to enhance the mortar properties. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5Synthetic Route of C6H20CaO11).

Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters.

Microwave-Assisted In Situ Synthesis of Poly L-Lactic Acid with Nanoparticles of Calcium Phosphate was written by Pandey, Anurag;Aswath, Pranesh. And the article was included in International Journal of Polymeric Materials in 2010.Category: alcohols-buliding-blocks This article mentions the following:

A microwave reactor was used to polymerize lactic acid and/or calcium lactate in the presence of phosphoric acid or ammonium hydrogen phosphate. The polar nature of lactic acid makes it a strong absorber of microwave radiation, and when present in a nonpolar solvent such as chloroform, it is possible to conduct the polymerization reaction in a microwave reactor. Using calcium lactate and ammonium hydrogen phosphate it is possible to create nanoparticles of calcium phosphate within the matrix of poly lactic acid in situ during the polymerization FTIR spectroscopy and gel permeation chromatog. were used to follow the polymerization process, and TEM was used to determine the size distribution of the calcium phosphate particles. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5Category: alcohols-buliding-blocks).

Simple conversion of 3D electrospun nanofibrous cellulose acetate into a mechanically robust nanocomposite cellulose/calcium scaffold was written by Lee, Joshua;Moon, Joon Yeon;Lee, Jeong Chan;Hwang, Tae In;Park, Chan Hee;Kim, Cheol Sang. And the article was included in Carbohydrate Polymers in 2021.HPLC of Formula: 5743-47-5 This article mentions the following:

Cellulose and its derivatives are widely used as nanofibrous biomaterials, but obtaining 3D cellulose nanofibers is difficult and relevant research is scarce. In the present study, we propose a simple method for converting electrospun 3D cellulose acetate/lactic acid nanofibers via calcium hydroxide treatment into a 3D cellulose/calcium lactate nanocomposite matrix. The conversion resulted in producing a stronger nanofibrous matrix (1.382 MPa vs. 0.112 MPa) that is more hydrophilic and cell-friendly compared to the untreated cellulose acetate/lactic acid group. The successful conversion was verified via FTIR, XPS, TGA, DTG, and XRD. The ability of the scaffolds to provide a suitable environment for cell growth and infiltration was verified by CCK assay and confocal microscopy. The porous nature, mech. strength, and presence of calcium make the 3D cellulose/calcium lactate matrix a promising material for bone tissue engineering. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5HPLC of Formula: 5743-47-5).
