4-coumaryl alcohol, also known as 4-hydroxycinnamyl alcohol or 4-coumaric acid, (E)-isomer, is a member of the class of compounds known as cinnamyl alcohols. Cinnamyl alcohols are aromatic alcohols containing a 3-phenylprop-2-en-1-ol moiety. 4-coumaryl alcohol is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 4-coumaryl alcohol can be synthesized from (E)-cinnamyl alcohol. 4-coumaryl alcohol is also a parent compound for other transformation products, including but not limited to, trans-coumaryl acetate, p-hydroxyphenyl lignin, and 4-hydroxy cinnamyl alcohol diacetate. 4-coumaryl alcohol can be found in a number of food items such as lemon balm, ginseng, red raspberry, and feijoa, which makes 4-coumaryl alcohol a potential biomarker for the consumption of these food products. 4-coumaryl alcohol can be found primarily in human testes tissue. Paracoumaryl alcohol, also called p-coumaryl alcohol, 4-coumaryl alcohol, 4-hydroxycinnamyl alcohol, or 4-(3-hydroxy-1-propenyl)phenol, is a phytochemical, one of the monolignols. It is synthesized via the phenylpropanoid biochemical pathway. When polymerized, p-coumaryl alcohol forms lignin or lignans .
