||The phi angle involves the carboxy carbon of the previous amino acid in a polypeptide chain. The psi angle involves the N of the subsequent amino acid. Therefore an isolated single amino acid has neither phi nor psi angles. | ||The phi angle involves the carboxy carbon of the previous amino acid in a polypeptide chain.
