Answer:
Explanation:
Maitotoxin
There are a number of potent marine toxins, such as Saxitoxin, which are often the cause of poisoning after eating contaminated shellfish. These are often associated with harmful algal blooms in the sea.
Maitotoxin is the most lethal of these substances, reckoned to have a LD50 about an order of magnitude less than batrachotoxin. Formed by a dinoflagellate, a kind of marine plankton, it has a very complicated structure, which presents a massive challenge to synthetic chemists. Maitotoxin is a cardiotoxin. It exerts its effects by increasing the flow of calcium ions through the cardiac muscle membrane, causing heart failure.
