WebAccording to the cross‐linkage theory of aging proposed by Johan Björkstein in 1942, aging results from the accumulation of intra‐ and intermolecular covalent bonds between molecules, termed “cross‐links.”. Over time, these cross‐links result in the alteration of the chemical and biological properties of the cell.
