Environmental toxicology: The toxicity and toxicology of environmental pollutants in air, dust, sediment, soil and water, and natural toxins in the environment.
Enzootic: Endemic in animals. An enzootic disease is constantly present in an animal population, but usually only affects a small number of animals at any one time.
Enzyme: Proteins that speeds up the rate of a chemical reaction in a living organism. An enzyme acts as catalyst for specific chemical reactions, converting a specific set of reactants (called substrates) into specific products. Without enzymes, life as we know it would not exist.
- Enzyme defect
Enzyme defect: A disorder resulting from a deficiency (or functional abnormality) of an enzyme. For example, newborns are routinely screened for certain enzyme defects, such as phenylketonuria (PKU) and galactosemia.
- Enzyme replacement
Enzyme replacement: A strategy designed to replace missing enzyme activity in a patient. This strategy currently involves the administration of a purified protein (the enzyme) by intravenous infusion.
- Enzyme, lysosomal
Enzyme, lysosomal: An enzyme in an organelle (a little organ) called the lysosome within the cell. Lysosomal enzymes degrade (break down) macromolecules (large molecules) and other materials (such as bacteria) that have been taken up by the cell during the process of endocytosis. In endocytosis, macromolecules and particles from outside the cell are taken up […]
