Degradation of Insulin
Once an insulin molecule has docked onto the receptor and effected its action, it may be released back into the extracellular environment or it may be degraded by the cell. Degradation normally involves endocytosis of the insulin-receptor complex followed by the action of insulin degrading enzyme. Most insulin molecules are degraded by liver cells. It has been estimated that a typical insulin molecule is finally degraded about 71 minutes after its initial release into circulation.

Famous quotes containing the words degradation of and/or degradation:
“The three great problems of this century, the degradation of man in the proletariat, the subjection of women through hunger, the atrophy of the child by darkness.”
—Victor Hugo (1802–1885)
“Why, since man and woman were created for each other, had He made their desires so dissimilar? Why should one class of women be able to dwell in luxurious seclusion from the trials of life, while another class performed their loathsome tasks? Surely His wisdom had not decreed that one set of women should live in degradation and in the end should perish that others might live in security, preserve their frappeed chastity, and in the end be saved.”
—Madeleine [Blair], U.S. prostitute and “madam.” Madeleine, ch. 10 (1919)
