3,4-Dihydroxyphenylalanine (DOPA) occurs transiently in nature as a free or peptide-bound amino acid. It is probably universally distributed in tissues and fluids of invertebrates. DOPA is a highly versatile metabolite, participating in neuroendocrine, immune, and reproductive functions, as well as in the formation of such products as bioadhesives, silks, integuments, and pigments. The mechanism by which DOPA is formed from tyrosine or peptidyl tyrosine remains to be determined in most cases. Future advances in DOPA chemistry may lead to a better understanding of the resonance between structural and sensory functions in animals.
3,4-二羟基苯丙氨酸（多巴）在自然界中以游离或肽结合氨基酸的形式短暂存在。它可能普遍分布于无脊椎动物的组织和体液中。多巴是一种高度通用的代谢产物，参与神经内分泌、免疫和生殖功能，以及生物粘合剂、丝绸、外皮和色素等产物的形成。在大多数情况下，由酪氨酸或肽基酪氨酸形成多巴的机制仍有待确定。多巴化学的未来进展可能会使人们更好地理解动物结构和感官功能之间的共振。
