4-Hydroxycinnamic acid

(E)-3-(4-hydroxyphenyl)prop-2-enoic acid

C9H8O3 (164.0473)


4-Hydroxycinnamic acid, also known as p-Coumaric acid, is a coumaric acid in which the hydroxy substituent is located at C-4 of the phenyl ring. It has a role as a plant metabolite. It is a conjugate acid of a 4-coumarate. p-coumaric acid is an organic compound that is a hydroxy derivative of cinnamic acid. There are three isomers of coumaric acid: o-coumaric acid, m-coumaric acid, and p-coumaric acid, that differ by the position of the hydroxy substitution of the phenyl group. p-Coumaric acid is the most abundant isomer of the three in nature. p-Coumaric acid exists in two forms trans-p-coumaric acid and cis-p-coumaric acid. It is a crystalline solid that is slightly soluble in water, but very soluble in ethanol and diethyl ether. 4-Hydroxycinnamic acid belongs to the class of organic compounds known as hydroxycinnamic acids. Hydroxycinnamic acids are compounds containing an cinnamic acid where the benzene ring is hydroxylated. 4-Hydroxycinnamic acid exists in all living species, ranging from bacteria to humans. Outside of the human body, 4-Hydroxycinnamic acid is found, on average, in the highest concentration within a few different foods, such as pepper (Capsicum frutescens), pineapples, and sunflowers and in a lower concentration in spinachs, kiwis, and sweet oranges. 4-Hydroxycinnamic acid has also been detected, but not quantified in several different foods, such as wild rices, soursops, garden onions, hyssops, and avocado. 4-coumaric acid is a coumaric acid in which the hydroxy substituent is located at C-4 of the phenyl ring. It has a role as a plant metabolite. It is a conjugate acid of a 4-coumarate. 4-Hydroxycinnamic acid is a natural product found in Ficus septica, Visnea mocanera, and other organisms with data available. trans-4-Coumaric acid is a metabolite found in or produced by Saccharomyces cerevisiae.
