GLAP, glyceraldehyde-derived pyridinium-type advanced glycation end product (AGE), formed by glyceraldehyde-related glycation, was identified in the plasma protein and the tail tendon collagen of streptozotocin (STZ)-induced diabetic rats. It was detected in the plasma protein and the collagen in diabetic rats by LC-MS and LC-MS/MS analysis, but was not(More)
The formation mechanisms of melanoidins as advanced glycation end products (AGEs) have not been resolved. Blue and red pigments generated in the D-xylose-glycine reaction system are postulated to be intermediate oligomers in the generation of melanoidins. A novel blue pigment, designated blue-M5, was identified as a similar structure to blue-M1 except for(More)
Protein is modified by carbonyl compound in the Maillard reaction, and the irreversible structure is formed as the advanced glycation end product (AGE). We identified GLAP (glyceraldehyde-derived pyridinium compound) as an AGE formed from glyceraldehyde and lysine residue of protein. In the present study, we investigated detection and determination of GLAP(More)
