WebThe Cross-Linking Theory. The Cross-Linking Theory of Aging is also referred to as the Glycosylation Theory of Aging. In this theory it is the binding of glucose (simple sugars) to protein, (a process that occurs under the presence of oxygen) that causes various problems. WebJul 31, 2024 · However, the levels of lysine glycation in collagen, which is not considered a cross-link, increased dramatically with age. We found that in 16-week-old diabetic db/db mice, glycation reaches levels similar to those observed in 98-week-old C57BL/6 mice, while the other cross-links typical of tendon collagen either decreased or remained the … east india dlr map WebJul 1, 1996 · Mechanistic studies have shown that collagen cross-linking in vitro can be uncoupled from glycation by the use of antioxidants and chelating agents. Experiments … WebNevertheless, Cerami's glycation theory warrants further testing. One avenue of approach is the use of such compounds as aminoguanidine, which prevent the protein cross-linking action of glucose (Brownlee et al., 1986).
