N-acetyldopamine plays a crucial role in the biochemical processes of insects, particularly in the formation and hardening of their exoskeletons. It acts as a precursor in the synthesis of cuticle, the outer protective layer of insects, contributing to their structural integrity and protection against environmental factors. Additionally, it is involved in the cross-linking of proteins during the sclerotization process, which enhances the mechanical strength and durability of the cuticle. This compound is also studied in the field of entomology for understanding insect development and in the development of bio-inspired materials that mimic the properties of insect exoskeletons.
