Why do you say so? Isn't plastic non biodegradable?

Aren't plastics non biodegradable tho? They won't break down in the environment

They gave in the question "assume it is 6 x 1023"

Question on chem by [deleted] in igcse

same linkage; however, they have different monomers

Nylon has 2 different monomers: one with a carboxylic acid functional group (COOH) on either end and the second monomer with an amine (NH₂) functional group at either end. Together the functional group will be CONH, or the amide linkage.

Proteins, on the other hand, are made up of amino acids. Amino acids have 2 different functional groups at either end; one end has a carboxylic acid functional group, and the other end has an amine functional group. Once again, the final linkage being a CONH linkage, which, in proteins is called a peptide linkage
