Only the l-arginine (symbol Arg or R) enantiomer is found naturally. [1] Arg residues are common components of proteins. It is encoded by the codons CGU, CGC, CGA, CGG, AGA, and AGG. [2] The guanidine group in arginine is the precursor for the biosynthesis of nitric oxide. [3] Like all amino acids, it is a white, water-soluble solid.
Arginylglycylaspartic acid (RGD) is the most common peptide motif responsible for cell adhesion to the extracellular matrix (ECM), found in species ranging from Drosophila to humans.
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
The second isozyme, Arginase II, has been implicated in the regulation of intracellular arginine/ornithine levels. It is located in mitochondria of several tissues in the body, with most abundance in the kidney and prostate. It may be found at lower levels in macrophages, lactating mammary glands, and brain. [5]

Methylated arginine is a modified version of arginine that is commonly formed from protein arginine (arginine incorporated in protein). Asymmetrically methylated forms of arginine are toxic when released during protein turnover. The protein detoxification pathway eliminates free methylated-arginine derivatives from the cell.
In arginylation, arginine (pictured above) is added to proteins. Arginylation is a post-translational modification in which proteins are modified by the addition of arginine (Arg) at the N-terminal amino group or side chains of reactive amino acids by the enzyme, arginyltransferase (ATE1). Recent studies have also revealed that hundreds of ...
It is structurally equivalent to a one-methylene group-higher homolog of arginine and to the guanidino derivative of lysine. L -Homoarginine is the naturally-occurring enantiomer . Physiologically , homoarginine increases nitric oxide (NO) supply and betters endothelial functions in the body, with a particular correlation and effect towards ...
