It occurs exclusively in the cytosol, where glutamate cysteine ligase (GCL) and glutathione synthetase (GS) perform their function
This was supported by the decreased levels of serine in the medium of 1919 cells compared to input media and 2012.2 cells ( p = 0.0129, p = 0.0027, respectively), as well as reduced synthesized serine and glycine into the media (Fig
Confirm the exact ratio with the manufacturers documentation before determining the liquid-to-peptide volume ratios for your laboratory equipment
Copper itself may also serve as a required cofactor for several angiogenic enzymes and transcriptional programs, and the GHK peptide appears to deliver copper in a biologically functional form at sites of cellular injury
It is a type of vitamin called a cofactor, meaning it helps enzymes break down amino acids, glucose, and fatty acids to help the body function properly
