Which theory explains the aging process as related to chemical bonding and tissue changes?

The Cross-Link Genetic Theory addresses the aging process by focusing on the biochemical changes that occur in the connective tissues and the effects of chemical bonding. This theory posits that as we age, harmful cross-linking of proteins can occur, which interferes with normal cellular function and contributes to the aging process. These cross-links can hinder the flexibility and functionality of various tissues, leading to physiological decline and the visible signs of aging.

In the context of aging, this theory emphasizes how chemical bonds, typically formed due to glycation, can lead to structural changes in tissues, affecting their performance and ultimately impacting overall health. Understanding this theory helps to illuminate one aspect of the complex mechanisms underlying aging, specifically how molecular changes can result in the broader physical and functional changes seen in elderly individuals.
