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.

An essential amino acid occurring naturally in the L-form, which is the active form. It is found in eggs, milk, gelatin, cottage cheese, poultry, fish, meat, lentils, sesame seeds and other proteins. Source: National Library of Medicine, MeSH 2006

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
