WebIn organic chemistry and biochemistry, a side chain is a chemical group that is attached to a core part of the molecule called the "main chain" or backbone.The side chain is a hydrocarbon branching element of a molecule that is attached to a larger hydrocarbon backbone. It is one factor in determining a molecule's properties and reactivity. A side … WebFor the simple case of cysteine and serine, the preferred values of the one side-chain torsion angle, denoted χ 1 , are 64°, -65° and 178°; these provide the maximum separation between the oxygen or sulfur and the other atoms of the amino acid. We describe these three preferred orientations of the side-chain as preferred "rotamers", and we ...

WebWhat types of interactions are involved in the catalytic triad of chymotrypsin, a serine protease enzyme that cleaves peptide bonds at the C-terminal of amino acid residues with non-polar side-chains (such as tryptophan, phenylalanine, and tyrosine) through a mechanism that utilizes both non-covalent and covalent catalysis within the enzyme … WebAmino acids are the compounds or building blocks that make up peptides and proteins. Each amino acid is structured from an amino group and a carboxyl group bound to a tetrahedral carbon. This carbon is designated as the α-carbon (alpha-carbon). Amino acids differ from each other with respect to their side chains, which are referred to as R groups.
