The amino-carbonyl cross-links induced by carbonyl stress are the central links in the molecular lesions of aging, which are the common process to form age pigments, such as lipofuscin, ceroid, AGEs and APFs. Moreover, the carbonyl-amino compounds have the highly active structures and can ceaselessly link and strangle the proteins, fats and nucleic acids around theirs, and the process can be more intense in the acidic microenvironment induced by the ischemia, hypoxia reductive damage in body. Therefore, the...
