octopamine profile

Octopamine is a biogenic amine neurotransmitter found in insects, crustaceans, and other invertebrates. It is synthesized from tyrosine, a precursor of dopamine, by the enzyme tyramine beta-hydroxylase. Octopamine plays a variety of roles in invertebrate physiology, including modulation of locomotion, learning and memory, stress response, and circadian rhythms. Its effects are mediated by G protein-coupled receptors. Octopamine is also involved in regulating the activity of the immune system and in promoting wound healing. The study of octopamine is important for understanding the nervous system and behavior of invertebrates, as well as for the potential development of new drugs for treating a variety of human conditions.'

Octopamine: An alpha-adrenergic sympathomimetic amine, biosynthesized from tyramine in the CNS and platelets and also in invertebrate nervous systems. It is used to treat hypotension and as a cardiotonic. The natural D(-) form is more potent than the L(+) form in producing cardiovascular adrenergic responses. It is also a neurotransmitter in some invertebrates. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

octopamine : A member of the class of phenylethanolamines that is phenol which is substituted at the para- position by a 2-amino-1-hydroxyethyl group. A biogenic phenylethanolamine which has been found to act as a neurotransmitter, neurohormone or neuromodulator in invertebrates.
