WebThe arginine side chain is very basic because its positive charge is stabilized by resonance. The two nitrogens of the histidine side chain have a relatively weak affinity for an H + and are only partly positive at neutral pH. Table 2: Charge of the amino acid side chains. Only the side chains are shown. WebNext ». This set of Protein Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Ramachandran Plot”. 1. Proteins are made up of amino acids.
