Part Descriptions

LP15946-4   Valine
Valine, one of the 20 proteinogenic amino acids, is nutritionally essential. It is named after the plant valerian. Foods that are good sources of valine include cottage cheese, fish, poultry, peanuts, sesame seeds, and lentils. In sickle cell disease, the replacement of an A by T in the beta chain gene of hemoglobin changes the codon GAG (for glutamic acid) to GTG (which encodes valine). Thus valine, a hydrophic amnio acid, replaces glutamic acid, a hydrophilic amino acid, causing hemoglobin to not fold correctly. It is also a precursor in the penicillin biosynthetic pathway.

LP15946-4   Valine
Valine is a branched-chain amino acid that stimulates activity and promotes muscle growth and tissue repair. It is elevated in branched-chain ketoaciduria (maple syrup urine disease), along with leucine, isoleucine, and alloisoleucine. Source: Regenstrief Institute

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.
