  <name>1-Methylhistidine</name>
  <description>1-Methylhistidine, also known as 1-mhis, 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. 1-Methylhistidine is possibly soluble (in water) and a very strong basic compound (based on its pKa). 1-Methylhistidine exists in all living organisms, ranging from bacteria to humans. 1-Methylhistidine participates in a number of enzymatic reactions, within cattle. In particular, 1-Methylhistidine and beta-alanine can be converted into anserine through its interaction with the enzyme carnosine synthase 1. In addition, beta-Alanine and 1-methylhistidine can be biosynthesized from anserine; which is mediated by the enzyme cytosolic non-specific dipeptidase. In cattle, 1-methylhistidine is involved in the metabolic pathway called the histidine metabolism pathway. 1-Methylhistidine has been found to be associated with several diseases known as eosinophilic esophagitis, early preeclampsia, and obesity; also 1-methylhistidine has been linked to several inborn metabolic disorders including maple syrup urine disease and propionic acidemia.</description>
