Liu, Xiaocui; Zhang, Zhicai; Xu, Ling; Shi, Wenjing; Sun, Quanshan; Ding, Chongyang; Zheng, Huihua; Wang, Feng published an article in LWT–Food Science and Technology. The title of the article was 《Dioscorea saponin transforms the structure of truffle exo-polysaccharide and enhances its antioxidant activity》.COA of Formula: C6H12O6 The author mentioned the following in the article:

Dioscorea saponin (DS) can increase the exo-polysaccharide production of Tuber melanosporum. In the present study, we assessed the effect of DS on the structure and antioxidant activity of exo-polysaccharide. In the absence of DS, only one exo-polysaccharide (TP1) composed of mannose, rhamnose and glucose was isolated. However, two exo-polysaccharides (STP1 and STP2) were isolated in the presence of DS. STP1 was composed of glucose, galactose and arabinose, and STP2 consisted of rhamnose, glucose, galactose and arabinose. The skeletal structure of TP1, STP1 and STP2 was composed of α-D-glucopyranose. The antioxidant activity of exo-polysaccharide exhibited a concentration-dependent manner. The DPPH radical-scavenging rate (61.37%) and total antioxidant activity (50.02%) of STP were higher compared with TP1. The STP increased the DPPH radical-scavenging rate depending on the increase of the maximum rate of the reaction at saturating substrate concentrations (kcat), while STP increased the reducing power depending on the kcat and affinity of substrate to STP. The inhibitory action of STP on hydroxyl radical generation depended on the blockage of Fe2+ by STP, making it unable to react with H2O2 to form ·OH, and STP could bind to the Fe2+- H2O2 complex and prevent the Fe2+ from turning H2O2 into product. In the part of experimental materials, we found many familiar compounds, such as rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1COA of Formula: C6H12O6)

The title of the article was 《Review: cascade reactions for conversion of carbohydrates using heteropolyacids as the solid catalysts》.Application In Synthesis of rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol The author mentioned the following in the article:

A review. Abstract: Conversion of biomass into renewable chems. and fuels has received significant attention as an approach to enhance global sustainability. Biomass conversion, especially carbohydrate conversion, commonly involves cascade reactions. During these cascade reactions, various activity sites on carbohydrates may have different reactivities that enable us to control the final products through adjusting these activity sites. Heteropolyacids (HPAs), one of the major solid acid catalysts, are extensively used in biomass conversion owing to their numerous excellent physicochem. properties, such as strong Bronsted acidity, oxidizability, structural versatility, and easy design. Accordingly, this review aims to outline recent breakthroughs in obtaining platform chems. from carbohydrates by cascade reactions involving heteropolyacid catalysts. Moreover, the relationship between the final products and the structure of heteropolyacid catalysts is discussed and insights will help us to design more efficient solid acid catalysts for conversion of biomass to more sustainable chem. products. The experimental part of the paper was very detailed, including the reaction process of rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1Application In Synthesis of rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol)

Monosaccharide transporters (MSTs) represent key components of the carbon transport and partitioning mechanisms in plants, mediating the cell-to-cell and long-distance distribution of a wide variety of monosaccharides. In this study, we performed a thorough structural, mol., and physiol. characterization of the monosaccharide transporter gene family in the model legume Medicago truncatula. The complete set of MST family members was identified with a novel bioinformatic approach. Prolonged darkness was used as a test condition to identify the relevant transcriptomic and metabolic responses combining MST transcript profiling and metabolomic anal. Our results suggest that MSTs play a pivotal role in the efficient partitioning and utilization of sugars, and possibly in the mechanisms of carbon remobilization in nodules upon photosynthate-limiting conditions, as nodules are forced to acquire a new role as a source of both C and N.rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1Name: rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol) was used in this study.

Computed Properties of C6H12O6On November 20, 2019 ,《Ellagitannins with Glucopyranose Cores Have Higher Affinities to Proteins than Acyclic Ellagitannins by Isothermal Titration Calorimetry》 appeared in Journal of Agricultural and Food Chemistry. The author of the article were Karonen, Maarit; Oraviita, Marianne; Mueller-Harvey, Irene; Salminen, Juha-Pekka; Green, Rebecca J.. The article conveys some information:

The thermodn. of the interactions of different ellagitannins with two proteins, namely, bovine serum albumin (BSA) and gelatin, were studied by isothermal titration calorimetry. Twelve individual ellagitannins, including different monomers, dimers, and a trimer, were used. The studies showed that several structural features affected the interaction between the ellagitannin and the protein. The interactions of ellagitannins with proteins were stronger with gelatin than with BSA. The ellagitannin-gelatin interactions contained both the primary stronger and the secondary weaker binding sites. The ellagitannin-BSA interactions showed very weak secondary interactions. The ellagitannins with glucopyranose cores had stronger interaction than C-glycosidic ellagitannins with both proteins. In addition, the observed enthalpy change increased as the degree of oligomerization increased. The stronger interactions were also observed with free galloyl groups in the ellagitannin structure and with higher mol. flexibility. Other smaller structural features did not show any overall trend. In the experimental materials used by the author, we found rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1Computed Properties of C6H12O6)

《Molecular structure of cefuroxime axetil complexes with α-, β-, γ-, and 2-hydroxypropyl-β-cyclodextrins: molecular simulations and Raman spectroscopic and imaging studies》 was published in International Journal of Molecular Sciences in 2021. These research results belong to Gieroba, Barbara; Kalisz, Grzegorz; Sroka-Bartnicka, Anna; Plazinska, Anita; Plazinski, Wojciech; Starek, Malgorzata; Dabrowska, Monika. HPLC of Formula: 54-17-1 The article mentions the following:

The formation of cefuroxime axetil + cyclodextrin (CA + CD) complexes increases the aqueous solubility of CA, improves its physico-chem. properties, and facilitates a biomembrane-mediated drug delivery process. In CD-based tablet formulations, it is crucial to investigate the mol. details of complexes in final pharmaceutical preparation In this study, Raman spectroscopy and mapping were applied for the detection and identification of chem. groups involved in α-, β-, γ-, and 2-hydroxypropyl-β-CD (2-HP- β-CD) + CA complexation process. The exptl. studies have been complemented by mol. dynamics-based investigations, providing addnl. mol. details of CA + CD interactions. It has been demonstrated that CA forms the guest-host type inclusion complexes with all studied CDs; however, the nature of the interactions is slightly different. It seems that both α- and β-CD interact with furanyl and methoxy moieties of CA, γ-CD forms a more diverse pattern of interactions with CA, which are not observed in other CDs, whereas 2HP-β-CD binds CA with the contribution of hydrogen bonding. Apart from supporting this interpretation of the exptl. data, mol. dynamics simulations allowed for ordering the CA + CD binding affinities. The obtained results proved that the mol. details of the host-guest complexation can be successfully predicted from the combination of Raman spectroscopy and mol. modeling. The results came from multiple reactions, including the reaction of rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1HPLC of Formula: 54-17-1)

SDS of cas: 54-17-1On October 15, 2020 ,《Microwave-assisted synthesis of nutgall tannic acid-based salecan polysaccharide hydrogel for tunable release of β-lactoglobulin》 was published in International Journal of Biological Macromolecules. The article was written by Hu, Xinyu; Yan, Linlin; Wang, Yongmei; Xu, Man. The article contains the following contents:

The low stability of β-lactoglobulin (βlg) under gastric conditions decreases the protein amount reaching the small intestine. Thus, it is crucial to develop a vehicle that can protect βlg from the stomach harsh acidity and enable its sustained and prolonged release in the small intestine. Herein, a fresh hydrogel composed of salecan-g-poly(N,N-dimethylaminoethyl acrylate) (PDMAEA) and nutgall tannic acid (TA) was fabricated by microwave-assisted polymerization The incorporation of salecan into hydrogels markedly affected the hydrogels thermal stability, microstructure, and mech. strength. Particularly, the multiple phenolic groups of TA can form complexes with βlg, and this enables the highly effective loading of proteins. As expected, βlg not only achieved effective entrapment into the hydrogels but also achieved a tunable and pH-controlled release. Such a release profile will enable βlg protection in the stomach and its targeted release in the small intestine. Increasing the salecan content dramatically enhanced the βlg release in simulated intestinal fluid (SIF). Furthermore, the βlg release was driven by Fickian diffusion in simulated gastric fluid (SGF), but the mechanism changed to non-Fickian diffusion in SIF. The release mechanism excellently matched Ritger-Peppas model. Overall, these results indicate that TA/salecan-g-PDMAEA hydrogels hold great potential for protein delivery in the gastrointestinal tract. The results came from multiple reactions, including the reaction of rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1SDS of cas: 54-17-1)
