WebCitrullination of arginine is catalyzed by the enzyme peptidylarginine-deiminase (PAD) in the presence of calcium, changing the positively charged arginine to a polar but neutral citrulline. These citrullinated peptides/proteins and the relevant antibodies (ACPA) are important, not only in initiation of RA, but also in the diagnosis of the disease. WebSep 15, 2024 · The amino acids are colorless, nonvolatile, crystalline solids, melting and decomposing at temperatures above 200°C. These melting temperatures are more like those of inorganic salts than those of amines or organic acids and indicate that the structures of the amino acids in the solid state and in neutral solution are best …
Arginine is the amino acid with the formula (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H. The molecule features a guanidino group appended to a standard amino acid framework.
