Structurally, chlorogenic Acid is the ester formed amid caffeic acerbic and L-quinic acid.
Isomers of chlorogenic Acid cover 4-O-caffeoylquinic acerbic (cryptochlorogenic Acid or 4-CQA), 5-O-caffeoylquinic acerbic (neochlorogenic Acid or 5-CQA). The epimer at position 1 has not yet been reported.
Isomers absolute two caffeic acerbic molecules are alleged isochlorogenic acid. It can be begin in coffee. There are several isomers such as 3,4-dicaffeoylquinic acerbic and 3,5-dicaffeoylquinic acid Cynarine (1,5-dicaffeoylquinic acid) is an added isomer with two caffeic acerbic molecules..
