WebThe deamination of phenylalanine by phenylalanine ammonia lyase (PAL) first produces cinnamic acid, which serves as the precursor for all of the phenylpropanoids of secondary metabolism. A cinnamic acid 4-hydroxylase (C4H) catalyzes the introduction of a hydroxyl group at the para position of the phenyl ring of cinnamic acid, producing coumaric ... The phenylpropanoids are a diverse family of organic compounds that are synthesized by plants from the amino acids phenylalanine and tyrosine. Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid, which is the central intermediate in phenylpropanoid biosynthesis. From 4-coumaroyl-CoA emanates the biosynthe…
