Your question: Is histamine acidic or basic?

Is histamine an acid?

Histamine is chemically classified as an amine, an organic molecule based on the structure of ammonia (NH3). It is formed by the decarboxylation (the removal of a carboxyl group) of the amino acid histidine.

What type of hormone is histamine?

Individuals who have unusually low levels of the enzyme diamine oxidase may be more susceptible to histamine toxicity.
