Part Descriptions

LP201692-3   Cytosine
Cytosine is a pyrimidine base found in DNA and RNA that pairs with guanine. Cytosine is deaminated into uracil by a number of cytosine deaminases. While cytosine deamination is part of normal physiology and signals certain DNA repair pathways, inappropriate deamination can create DNA mutations and has been associated with the development of certain types of solid tumors and lymphoma.

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.
