WebJul 1, 1988 · Diabetes and aging are associated with an increase in collagen-linked fluorescence and cross-linking that can be duplicated by incubating collagen with glucose. We have tested the hypothesis that browning and cross-linking can occur in vivo in rats by feeding them a diet containing 33% galactose. WebSep 17, 2009 · The first step of AGEs cross-link formation of collagen is that the aldehyde of an open chain form of glucose, ketose, or other metabolic intermediate (glyoxal, methylglyoxal, and 3-deoxyglucosone) reacts with a free ε-amino group of collagen-bound Lys or Hyl to form a glycosyl-Lys via Schiff base formation [ 82 ].
