LP15425-9   Aspartate
Aspartic acid (Asp), also known as aspartate, the name of its anion, is one of the 20 natural proteinogenic amino acids which are the building blocks of proteins. As with each of the 20 natural amino acids, there are two abbreviations commonly used to designate aspartic acid: Asp (three letter) and D (one letter). The abbreviations signifying a choice of either aspartic acid or asparagine are Asx (three-letter) and B (one letter). As its name indicates, aspartic acid is the carboxylic acid analog of asparagine. It is non-essential in mammals, and might serve as an excitatory neurotransmitter in the brain. It is also a metabolite in the urea cycle, and participates in gluconeogenesis. As a neurotransmitter, aspartic acid may provide resistance to fatigue and thus lead to endurance, although the evidence to support this idea is not strong.

LP15425-9   Aspartate
Aspartic acid is a dicarboxylic amino acid with acidic R groups which is a cosubstrate with glutamic acid for aspartate aminotransferase (AST). Aspartic acid is used in pyrimidine biosynthesis and is a metabolite in the urea cycle and participates in gluconeogenesis. Increased in dicarboxylic aminoaciduria.

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.
