Arginine Side Chain Interactions And The Role Of Arginine As A
Arginine may prevent or treat heart and circulatory diseases combat fatigue and stimulate the immune system.
Arginine side chain. This arginine preference may result from the unique hydration properties of the side chain guanidinium group which facilitates its movement through a. Arginine residues are often crucial to many biological interaction interfaces because the flexible arginine sidechain consisting of a chain of aliphatic carbon atoms and a terminal guanidinium group is capable of an array of hydrogenbonds and other interactions. Arginine r arg in the urea cycle the enzyme arginase cleaves hydrolyzes the guanidinium group to yield urea and the l amino acid ornithine.
L ornithine is not normally found in proteins. Gating charges in voltage sensing domains vsd of voltage sensitive ion channels and enzymes are carried on arginine side chains rather than lysine. Arginines side chain is amphipathic because at physiological ph it contains a positively charged guanidinium group which is highly polar at the end of a hydrophobic aliphatic hydrocarbon chain.
Arginine is an essential amino acid in juvenile humans arginine is a complex amino acid often found at active site in proteins and enzymes due to its amine containing side chain.
