Indicators
A water-soluble vitamin ubiquitously found in plants and animal tissues with antioxidant property. Vitamin B5 is a component of coenzyme A (CoA) and a part of the vitamin B2 complex. Vitamin B5 is a growth factor and is essential for various metabolic functions, including the metabolism of carbohydrates, proteins, and fatty acids. This vitamin is also involved in the synthesis of cholesterol, lipids, neurotransmitters, steroid hormones, and hemoglobin.
Tests
The determination of the amount of procollagen 3 N-terminal propeptide present in a sample.
Article
Research record from J Am Soc Mass Spectrom, 2026-10-01. PMID 42916769.
Tests
The determination of the S-benzyl mercapturic acid present in a sample.
Indicators
Somatotropin (217 aa, ~25 kDa) is encoded by the human GH1 gene. This protein is involved in the regulation of many physiologic processes, including the growth of organs and tissues and the metabolism of amino acids and proteins.
Tests
The determination of the ratio of the type 1 collagen X-link N-telopeptides compared to creatinine present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the amount of the type I collagen N-telopeptide present in a sample.
Indicators
A synthetic derivative of propylpentanoic acid with antiepileptic properties and potential antineoplastic and antiangiogenesis activities. In epilepsy, valproic acid appears to act by increasing the concentration of gamma-aminobutyric acid (GABA) in the brain. This agent's antitumor and antiangiogenesis activities may be related to the inhibition of histone deacetylases and nitric oxide synthase, which results in the inhibition of nitric oxide synthesis.

Glossary Term
A measure of the variability in a sample or population. It is calculated as the mean squared deviation (MSD) of the individual values from their common mean. In calculating the MSD, the divisor n is commonly used for a population variance and the divisor n-1 for a sample variance.
