WebPhenylalanine (Phe or F) is an amino acid present in proteins. Structure of phenylalanine. Like all of the amino acids, phenylalanine has two functional groups, an amine group (NH 2) and a carboxyl group (COOH). Its side chain consists of a benzene ring attached to the central carbon atom by a CH 2 group. It is a non-polar, aromatic, amino acid. http://russelllab.org/aas/Phe.html WebThe side chain conformations, so called rotamers, cluster around energetically preferred conformations. Side chain dihedrals Chi (Χ) angles defining side chain conformations in a lysine-tyrosine di-peptide. The Χ 1 angle is subject to restrictions due to steric hindrance between the γ side chain atom (s) and the main chain. black lightning shoes
