The phytochemical study was carried out using repeated silica gel column chromatography followed by Sephadex LH-20 to purify the extract which afforded three known compounds: lutein (1), shikimic acid (2) and guaiacylglycerol (3). The structures of these compounds were identified after analyses of...
Its antioxidant activity is 10 times higher than that of zeaxanthin, lutein, keratanin, β-carotene and 100 times higher than that of α-tocopherol. This is related to the unique molecular structure of astaxanthin, with hydroxyl and ketone groups on each ionic ring. The polyene chains in ...
The research progress of using random mutagenesis, metabolic engineering, enzyme engineering and other methods to improve the synthesis and accumulation of astaxanthin in bacteria, yeast, and marine eukaryotic microorganisms is summarized. This article can provide theoretical guidance for the research on ...
Arbutin is one of the most commonly used skin care ingredients to lighten skin. Alpha Arbutin vs Beta Arbutin There are two forms of arbutin found in skincare. They have the same chemical structure but different rotational configurations which gives th...

Lutein transport by Caco-2 TC-7 cells occurs partly by a facilitated process involving the scavenger receptor class B type I (SR-BI) (scavenger receptor class B type 1) and (viii) in the presence of increasing concentrations of a chemical inhibitor of the selective transfer of lipids ... ...
Deep eutectic solvents offer extraordinary properties, hence finds applicability in diverse spheres of catalysis, medicine, metal decomposition, protein science and gas adsorption. Compared to conventional solvents, DESs display exclusive properties such as very low vapor pressure, recyclability, enhanced solu...
