Sarcosine (BioDeep_00000003015)

描述信息

Sarcosine is the N-methyl derivative of glycine. Sarcosine is metabolized to glycine by the enzyme sarcosine dehydrogenase, while glycine-N-methyl transferase generates sarcosine from glycine. Sarcosine is a natural amino acid found in muscles and other body tissues. In the laboratory it may be synthesized from chloroacetic acid and methylamine. Sarcosine is naturally found in the metabolism of choline to glycine. Sarcosine is sweet to the taste and dissolves in water. It is used in manufacturing biodegradable surfactants and toothpastes as well as in other applications. Sarcosine is ubiquitous in biological materials and is present in such foods as egg yolks, turkey, ham, vegetables, legumes, etc. Sarcosine is formed from dietary intake of choline and from the metabolism of methionine, and is rapidly degraded to glycine. Sarcosine has no known toxicity, as evidenced by the lack of phenotypic manifestations of sarcosinemia, an inborn error of sarcosine metabolism. Sarcosinemia can result from severe folate deficiency because of the folate requirement for the conversion of sarcosine to glycine (Wikipedia). Sarcosine has recently been identified as a biomarker for invasive prostate cancer. It was found to be greatly increased during prostate cancer progression to metastasis and could be detected in urine. Sarcosine levels were also increased in invasive prostate cancer cell lines relative to benign prostate epithelial cells (PMID: 19212411).
Sarcosine, also known as N-methylglycine or (methylamino)acetic acid, is a member of the class of compounds known as alpha amino acids. Alpha amino acids are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Sarcosine is soluble (in water) and a moderately acidic compound (based on its pKa). Sarcosine can be found in peanut, which makes sarcosine a potential biomarker for the consumption of this food product. Sarcosine can be found primarily in most biofluids, including blood, saliva, cerebrospinal fluid (CSF), and feces, as well as in human muscle, prostate and skeletal muscle tissues. Sarcosine exists in all living organisms, ranging from bacteria to humans. In humans, sarcosine is involved in few metabolic pathways, which include glycine and serine metabolism, methionine metabolism, and sarcosine oncometabolite pathway. Sarcosine is also involved in several metabolic disorders, some of which include homocystinuria-megaloblastic anemia due to defect in cobalamin metabolism, cblg complementation type, hyperglycinemia, non-ketotic, hypermethioninemia, and dimethylglycine dehydrogenase deficiency. Moreover, sarcosine is found to be associated with sarcosinemia. Sarcosine is a non-carcinogenic (not listed by IARC) potentially toxic compound.

Sarcosine (N-Methylglycine), an endogenous amino acid, is a competitive glycine transporter type I (GlyT1) inhibitor and N-methyl-D-aspartate (NMDA) receptor co-agonist. Sarcosine increases the glycine concentration, resulting in an indirect potentiation of the NMDA receptor. Sarcosine is commonly used for the research of schizophrenia[1][2].
