The structure of side chains that react to form the cross-links of protein chains are to be shown and a mechanism for their formation in a weakly acidic solution is to be proposed. Concept introduction: Collagen is a fibrous protein in connective tissue. In the structure of collagen, crosslinks containing alpha and beta-unsaturated aldehydes between protein chains are present. Collagen gives strength and elasticity to skin and replaces dead skin cells.

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.
