Domoic acid
Domoic Acid
Domoic acid (pronunciation: /dəˈmoʊ.ɪk ˈæsɪd/) is a potent neurotoxin produced by certain species of marine diatoms (genus Pseudo-nitzschia) and the red alga Chondria armata.
Etymology
The term "domoic acid" derives from the red alga Chondria armata, commonly known as "Domo" in Japan, from which the toxin was first isolated.
Description
Domoic acid is a structural analog of the neurotransmitter glutamate. Due to its similarity with glutamate, domoic acid can cause overexcitation of neurons, leading to neurological damage and, in severe cases, death. This condition is known as Amnesic Shellfish Poisoning (ASP).
