Gallocatechin gallate (GCG) is the ester of gallocatechin and gallic acid and a type of catechin. It is an epimer of epigallocatechin gallate (EGCG). In a high temperature environment an epimerization change is likely to occur because heating results in the conversion from EGCG to GCG. According to the referenced study the resulting CGC (the epimer of EGCG) results in even lower dietary cholesterol absorption than occurs with EGCG.
