What is Epicatechinegallate with CAS 1257-08-5
(-) -epicatechin gallate, referred to as EGCG, is an ester formed by gallic catechin and gallic acid, belonging to a kind of tea polyphenols, is a flavonoid, right ester type catechin. Epicatechin gallate is a catechin monomer isolated from tea, and is the main component of the biological activity of tea polyphenols.

Application
One of the catechin isomers and a potent antioxidant that can modulate a wide range of membrane proteins. Its bilayer-modifying potency was tested using gramicidin A (gA) channels as probes. All the c atechins alter gA channel function and modify bilayer properties, with a 500-fold range in potency. The gallate group causes current block, as evident by brief downward current transitions.
