Phi and psi angles amino acids
WebA dipeptide would have two amino acids. That would be the smallest possible peptide, but then you could keep adding amino acids and form polypeptides. And a very high-level overview of this reaction is that this nitrogen uses its lone pair to form a bond with this carbonyl carbon right over here. WebThe Greek letter psi (Ψ or ψ) is used for angles in biochemistry. In Foldit, psi and the closely related phi generally refer to the two critical angles of the protein backbone. Phi and psi …
