Part Descriptions

LP200579-3   S-adenosylhomocysteine
S-Adenosylhomocysteine (SAH) is formed by the demethylation of S-adenosylmethionine (SAMe) and is rapidly metabolized to homocysteine. The reaction of SAH to homocysteine is catalyzed by S-adenosylhomocysteine hydrolase and is reversible with the equilibrium favoring formation of SAH. Therefore, increased levels of SAH may occur when the intracellular concentration of homocysteine increases. Since SAH is known to inhibit methylation dependent reactions, the ratio of SAMe to SAH is often used as an index of methylation status. Disturbances in the transmethylation pathway indicated by abnormal SAMe, SAH or their ratio have been reported in many neurodegenerative diseases, such as dementia, depression or Parkinson's disease.

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.
