20658-1Threonine [Moles/volume] in Serum or PlasmaActive

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

LP15890-4   Threonine
Threonine, one of the 20 naturally occuring amino acids, is nutritionally essential in humans because they cannot synthesze it. Threonine contains two chiral centers, so there are four possible stereoisomers of threonine, or two possible diastereomers of L-threonine. However, the name L-threonine is used for one single enantiomer, (2 S ,3 R)-2-amino-3-hydroxybutanoic acid. The second diastereomer (2 S ,3 S), which is rarely present in nature, is called L-allo-threonine. The threonine side chain can undergo O-linked glycosylation. Threonine can become phosphorylated through the action of a threonine kinase. In its phosphorylated form, it is referred to as phosphothreonine. Foods high in threonine are cottage cheese, poultry, fish, meat, lentils, and sesame seeds. Threonine is a secondary marker for citrullinemia type II, an inherited disorder that causes ammonia and other toxic products to accumulate in the blood.
