Uptake and metabolism of water-borne progesterone by the mussel, Mytilus spp. (Mollusca).

Previous studies have shown that mussels can pick up 17β-estradiol [E2] and testosterone [T] from water, metabolize them and conjugate them to fatty acids (esterification), leading to their accumulation in tissue. A key requirement for the esterification process is that a steroid must have a 'reactive' hydroxyl group to conjugate to a fatty acid (which in T… CONTINUE READING
