Part Descriptions

LP15807-8   Phytanate
Phytanic acid (or 3,7,11,15-tetramethyl hexadecanoic acid) is present in human diet or in animal tissues where it may be derived from chlorophyll in plant extracts. Phytanic acid derives from the corresponding alcohol, phytol , and is oxidized into pristanic acid. It can also characterize a precise human pathology, Refsum's syndrome. This inherited neurological disorder is characterized by an accumulation of a normal metabolite of phytol (phytanic acid) in blood and tissues, and the disorder was later found to be related to deficiency in the oxidation pathway in the liver. Freshwater sponges contain terpenoid acids such as 4,8,12-trimethyltridecanoic, phytanic and pristanic acids, which indicates that these acids may have chemotaxonomical significance for both marine and freshwater sponges. Phytanic acid accumaltes in the fat of ruminant animals. Most animals lack the necessary enzyme to cleave phytol from chlorophyll.

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.
