Degradation
Definition:

(n.) The state of being reduced in rank, character, or reputation; baseness; moral, physical, or intellectual degeneracy; disgrace; abasement; debasement.
(n.) Diminution or reduction of strength, efficacy, or value; degeneration; deterioration.
(n.) A gradual wearing down or wasting, as of rocks and banks, by the action of water, frost etc.
(n.) The state or condition of a species or group which exhibits degraded forms; degeneration.
(n.) Arrest of development, or degeneration of any organ, or of the body as a whole.

(5) Addition of extracellular mevalonate led to a concentration-dependent fall in both processes, although a higher concentration was required to produce the same effect on LDL degradation as on HMG-CoA reductase activity.
(6) Radioiodinated a-factor was used to identify the a-factor-degrading activity, which is cell associated, endoproteolytic, and not required for response to pheromone.
