Cross linked theory of aging
WebThe cross-linking theory, also referred to as the glycosylation theory of aging, was proposed by Johan Bjorksten in 1942. According to this theory, an accumulation of cross-linked … This cross-linking theory is the idea that chemical changes like this happen in your body and can lead to aging. The process is slow and complicated, but over time, more and more proteins, DNA and other structural molecules in the body develop inappropriate attachments, called cross-links, to one another. See more When you heat onions or toast bread, the sugar molecules in the foods bond to protein molecules. This bonding, which in cooking is called caramelization, is a result of the sugar molecules attaching to protein molecules. When this … See more When cross-linking occurs, tissues become stiffer, and when tissues stiffen they don't function as efficiently.
