(2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Formula: C30H26O12

A comprehensive study of the differences in protein expression and chemical constituents in tea leaves (Camellia sinensis var. sinensis) with different maturity using a combined proteomics and metabolomics method was written by Sun, Zhen;Chen, Dan;Zhu, Liyao;Zhao, Yanni;Lin, Zhi;Li, Xianzhen;Dai, Weidong. And the article was included in Food Research International in 2022.Formula: C30H26O12 The following contents are mentioned in the article:

The maturity of tea leaves has a great influence on the flavor quality and com. price of tea. In this work, a combined proteomics and metabolomics anal. was applied to investigate the differences in protein expression and metabolites among tea leaves with different maturity. Integrated anal. showed that there were significant differences in 112 nonvolatile components related to the pathways of photosynthesis, glycolysis, tricarboxylic acid cycle, and the biosynthesis of amino acids, phenylpropanoids and flavonoids. The bud had higher expression levels of most enzymes related to the biosynthesis of amino acids, phenylpropanoids, and flavonoids, leading to higher levels of amino acids, most flavanols, and procyanidins compared with the leaves. The 1st leaf showed a higher expression level of flavonol synthase, which produces higher levels of flavonol-3-glycosides. This study offers deep insight into the maturity of tea at both the protein and metabolite levels and provides a guideline for tea manufacturing This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Formula: C30H26O12).
