Google Scholar. Med. I. Exp. The first stage of glycation is the reversible reaction of an electrophilic carbonyl group or hemiacetal reducing sugar with the free amino group of amino acids (most commonly lysine and arginine). Article In the Maillard reaction, the amine moiety from free amino acids, peptides, or proteins reacts with the carbonyl group of a reducing sugar, oxidized lipids, vitamin C, or quinones. It is considered an important indicator of the excretory function of the kidneys. The values given are the mean of the results obtained during the experiments and the standard errors of the mean (Mean SE). They also occur in vivo in living organisms between reducing sugars, such as glucose or fructose, and amino acids, peptides or proteins containing a free amino groups. AGEs can also cause glycation of LDL which can promote its oxidation. Although their relationship to the level of kidney function has not been well characterized, we know that AGEs are responsible for a number of health conditions. This occurs by inhibiting glycation and intermediates 14.
