Part Descriptions

LP15753-4   Ornithine
Ornithine is an amino acid that, under the action of the enzyme arginase on L-arginine, yields urea. Therefore, ornithine is a central part of the urea cycle, which eliminates excess nitrogen. Ornithine is not an amino acid coded by DNA, and in that sense, it is not involved in protein synthesis. In mammalian non-hepatic tissues, however, the urea cycle is mainly involved in arginine biosynthesis, making ornithine an important metabolic process. It is not directly a product of the the genetic code because polypeptides containing unprotected ornithines undergo spontaneous lactamization. This proved to be a problem when ornithine was originally classified among the other 20 naturally occuring amino acids.

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.
