Citrulline antibody (health)


An antibody (an immune protein) directed against a circular peptide (a ring of amino acids) containing an unusual ("non-standard") amino acid called citrulline that is not normally present in peptides or proteins. (Citrulline is formed by the body as an intermediary in the conversion of the amino acid orthithine to arginine). The citrulline antibody provides the basis for a test of importance in rheumatoid arthritis.
