Selected stereochemical parameters of amino acids and nucleosides. (A) Chirality configuration at C α of an amino acid; (B) chiral centers at the ribose moiety of guanosine monophosphate; (C) cis and trans isomers of a peptide group. Carbon atoms are shown in green, nitrogen in blue, oxygen in red, and hydrogen in white. Chiral centers are surrounded by a transparent purple sphere.
