Step-by-step solution
Aquaporins are protein ion channels that facilitate the transport of water. Thus, chemically they are polypeptide in nature. Asparagine is an amino acid with - CONH 2 group in the side chain. Thus, it is chemically an amide. Chitin is a mucopolysaccharide of the monomer N - acetylglucosamine. It is found in the cell wall of fungi and in the exoskeleton of arthropods. Abscisic acid (ABA), synthesised in response to water stress, is an apocarotenoid.
