Sarcosine in a N-methylglycine.
Structure of a N-methylglycine:
It’s an intermediate in glycine synthesis and degradation as you can look on this schema:
It’s an good antibacterial and anti fungal too. Able to form a bidentate complexe according to a carboxyl ion and can coordinates several metals, for instance Zn.
Some complexes containing Sn and Zn are very soluble in lipids. Consequently, these complexes can easily enter into the cell.
Lot of studies are made about Sarcosine and it function and confirm this.
