Phenylalanine functional group
Did you know?
Phenylalanine (symbol Phe or F) is an essential α-amino acid with the formula C 9H 11NO 2. It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. This essential amino acid is classified as neutral, and nonpolar because of the inert and hydrophobic nature of the benzyl side chain. The L-isomer is used to bioche… WebPhenyl groups are closely related to benzene and can be described as a benzene ring, minus a hydrogen, which can be substituted as a functional group by any other element or …
