Aquatic animals are exposed to a variety of natural and
anthropogenic xenobiotics. Biotransformation of xenobiotics was
examined in three aquatic animals: a primitive mollusc (chiton);
a shellfish which is an important human food source (oyster);
and, a lower vertebrate model for toxicological studies (rainbow
trout). Since digestive glands of Cryntochiton...
Lipids, especially phospholipids, are very common
but important molecules found in cells and animal
tissue, performing many biological functions, particularly
in membranes. Lipids, when mixed with water,
spontaneously form ordered systems, such as micelles,
vesicles and multibilayers. The size of these systems
and their degree of ordering depend on the...
