Heres what your GGT level can tell you about longevity: Oxidative Stress Status: It shows the balance between damaging free radicals and the antioxidants that protect you, which is a core component of biological ageing
For example, the formation of an isopeptide bond between the sidechains of lysine and glutamine is as follows: Gln(C=O)NH 2 + Lys-NH 3 + Gln(C=O)NHLys + NH 4 + The -amino group of lysine can also react with the -carboxyl group of any other amino acid as in the following reaction: Ile-(C=O)O + Lys-NH 3 + Ile-(C=O)NH-Lys + H 2 O Isopeptide bond formation is typically enzyme-catalyzed
However, its important to note: Not all studies show dramatic whitening results

For example, as we have seen, all common amino acids are L because they all have the same structure, including the position of the R group (if we just write the R group as R)
