Term Description

Genetic metabolic specialist (from Canada) point out that plasma may be the traditional sample of choice, but they see no clinically significant difference between plasma and serum amino acids.

Part Descriptions

LP15521-5   Cysteine
Cysteine is a naturally occurring, sulfur-containing (sulfhydryl) amino acid which has a thiol group and is found in most proteins, though only in small quantities. Cysteine is in the same class as methionine. When it is exposed to air, cysteine oxidizes to form cystine , which is a dimer of two cysteine molecules joined by a weak disulfide bond. N-acetyl-L-cysteine (NAC) is derived from cysteine and is a popular dietary supplement that is metabolized into the antioxidant glutathione. Cysteine takes its name from cystine, named after the Greek kustis meaning bladder ˆ' cystine was first isolated from kidney stones. Because it is a sulfur-based amino acid, cysteine itself can act as an antioxidant in the body. Cysteine is an important source of sulfur in human metabolism, and although it is classified as a non-essential amino acid, cysteine may be essential for infants, the elderly, and individuals with metabolic disease or who suffer from malabsorption syndromes.
