Structure of Dopamine

A dopamine atom consists of a catechol anatomy (a benzene ring with two hydroxyl ancillary groups) with one amine accumulation absorbed via an ethyl chain. As such, dopamine is the simplest accessible catecholamine, a ancestors that aswell includes the neurotransmitters norepinephrine and epinephrine. The attendance of a benzene ring with this amine adapter makes it a commissioned phenethylamine, a ancestors that includes abundant consciousness-expanding drugs.
Like a lot of amines, dopamine is an amoebic base. As a base, it is about protonated in acerb environments (in an acid-base reaction).The protonated anatomy is awful water-soluble and almost stable, but can become breakable if apparent to oxygen or added oxidants. In basal environments, dopamine is not protonated. In this chargeless abject form, it is beneath water-soluble and aswell added awful reactive.Because of the added adherence and water-solubility of the protonated form, dopamine is supplied for actinic or biologic use as dopamine hydrochloride—that is, the hydrochloride alkali that is created if dopamine is accumulated with hydrochloric acid. In dry form, dopamine hydrochloride is a accomplished achromatic powder.
