Descrição geral

Catechins are phytochemicals, richly present in black grapes, peaches, strawberries and broad beans. Catechins occur in various forms such as catechins, epicatechin, epicatechin gallate, epigallocatechin and epigallocatechin gallate.


(+)-Catechin hydrate has been used:
  • as a polyphenol standard in the determination of total polyphenols in the by-products of red wine
  • as an additive to study its effects on in vitro methane production and substrate degradation in a triple-fed batch approach
  • as a substrate to determine the activity of pure L. plantarum CECT 748T 14 recombinant tannase on catechin

Ações bioquímicas/fisiológicas

An antioxidant flavonoid of plant origin; a free radical scavenger, preventing free radical-mediated damage in a variety of biological systems. For example, at physiological pH catechin suppressed DNA strand breaks by hydroxyl radicals. It has also been shown to prevent human plasma oxidation. It delayed the consumption of endogenous lipid-soluble antioxidants and inhibited lipid oxidation. Catechin may also function as an inhibitor of fatty acid synthase.

Catechin hydrate is a phytopharmaceutical with promising anticancer effects but poor bioavailability. This study aimed to elaborate catechin loaded chitosan-tethered liposomes (chitosomes) to enhance catechin oral bioavailability. Nanocarriers were optimized via ethanol injection method followed by physicochemical, ex vivo and

Increases in the environmental osmolarity are key determinants for the growth of microorganisms. To ensure a physiologically acceptable level of cellular hydration and turgor at high osmolarity, many bacteria accumulate compatible solutes. Osmotically controlled uptake systems allow the scavenging of

The reactivities of various antioxidative compounds including catechol derivatives and endogenous radical scavengers toward hydroxyl radical (.OH) were investigated by an electron spin resonance-spin trapping method, thiobarbituric acid method, and DNA strand scission assay. Hydroxyl radical was generated by both

Fatty Acid Synthesis and Metabolism in Cancer Cells

Information on fatty acid synthesis and metabolism in cancer cells. Learn how proliferatively active cells require fatty acids for functions such as membrane generation, protein modification, and bioenergetic requirements. These fatty acids are derived either from dietary sources or are synthesized by the cell.

Dietary Antioxidants

Antioxidants protect biological systems from oxidative damage produced by oxygen-containing free radicals and from redoxactive transition metal ions such as iron, copper, and cadmium.
