lhistidine

L-Histidine (L-(-)-Histidine) is a semi-essential amino acid (children should obtain it from food) needed in humans for growth and tissue repair, L-Histidine is important for maintenance of myelin sheaths that protect nerve cells and is metabolized to the neurotransmitter histamine. Histamines play many roles in immunity, gastric secretion, and sexual functions. L-Histidine is also required for blood cell manufacture and protects tissues against damage caused by radiation and heavy metals.

Histidine (abbreviated as His or H) is an alpha-amino acid. The L-isomer is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. It is classified as a charged, polar because of the hydrophilic nature of the imidazole side chain.

N-Acetyl-L-histidine monohydrate is a natural product for research related to life sciences. The catalog number is T38094 and the CAS number is 39145-52-3.

L-Carnosine (Karnozin) is is an antioxidant naturally found in skeletal muscle, brain tissue. It has the potential to suppress many of the biochemical changes that accompany aging.

1-Methyl-L-histidine (3-(1-Methylimidazol-4-yl)-L-alanine) is a natural but non-proteinogenic amino acid; employed as index of muscle protein breakdown.

3-Methylhistidine belongs to the class of organic compounds known as histidine and derivatives. Histidine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group

L-Histidine (Standard) is a reference standard for research and analysis in studies involving L-Histidine.

1-Methyl-L-histidine (Standard) is a reference standard for research and analysis in studies involving 1-Methyl-L-histidine. 1-Methyl-L-histidine (3-(1-Methylimidazol-4-yl)-L-alanine) is a natural but non-proteinogenic amino acid; employed as index of muscle protein breakdown.

3-Methyl-L-histidine (Standard) is a reference standard for research and analysis in studies involving 3-Methyl-L-histidine. 3-Methylhistidine belongs to the class of organic compounds known as histidine and derivatives. Histidine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. It is also a biomarker for the consumption of soy products. 3-Methylhistidine is a very strong basic compound (based on its pKa). 3-Methylhistidine exists in all eukaryotes, ranging from yeast to humans. In humans, 3-methylhistidine is involved in methylhistidine metabolism. 3-Methylhistidine, with regard to humans, has been found to be associated with several diseases such as diabetes mellitus type 2, eosinophilic esophagitis, and kidney disease; 3-methylhistidine has also been linked to the inborn metabolic disorder propionic acidemia. The measurement of 3-methylhistidine provides an index of the rate of muscle protein breakdown. 3-Methylhistidine is a product of peptide bond synthesis and methylation of actin and myosin. 3-Methylhistidine is a biomarker for meat consumption, especially chicken.Structure
