Amino Acids, Sulfur

Medical Definition:

Amino Acids, Sulfur Categories.

	Cysteic Acid - Beta-Sulfoalanine. An amino acid with a C-terminal sulfonic acid group which has been isolated from human hair oxidized with permanganate. It occurs normally in the outer part of the sheep's fleece, where the wool is exposed to light and weather.
	Ethionine - 2-Amino-4-(ethylthio)butyric acid. An antimetabolite and methionine antagonist that interferes with amino acid incorporation into proteins and with cellular ATP utilization. It also produces liver neoplasms.
	Homocysteine - A thiol-containing amino acid formed by a demethylation of METHIONINE.
	Penicillamine - 3-Mercapto-D-valine. The most characteristic degradation product of the penicillin antibiotics. It is used as an antirheumatic and as a chelating agent in Wilson's disease.
	Thiopronine - Sulfhydryl acylated derivative of GLYCINE.
	Thiorphan - A potent inhibitor of membrane metalloendopeptidase (ENKEPHALINASE). Thiorphan potentiates morphine-induced ANALGESIA and attenuates naloxone-precipitated withdrawal symptoms.
