'''Coutaric acid''' is a type of [[hydroxycinnamic acid]], a class of [[organic compounds]] that are commonly found in the plant kingdom. Hydroxycinnamic acids are a subgroup of [[phenolic acids]], which are widely recognized for their role in plant metabolism and their contribution to the organoleptic qualities of fruits and vegetables, such as color, flavor, and aroma. Coutaric acid, specifically, is a derivative of [[cinnamic acid]] that is conjugated with tartaric acid, giving it unique properties compared to other hydroxycinnamic acids.
