WebbProtein catabolism Proteins are first hydrolyzed to individual amino acids. The amino group nitrogens are stripped off and sent to the urea cycle. The remaining carbon skeletons are converted to pyruvate, acetyl-CoA, or various intermediates of the citric acid cycle, depending on the amino acid. WebbThe relative susceptibility of a protein to degradation is expressed as its half-life (t1/2), the time required to lower its concentration to half of its initial value. Half-lives of liver proteins range from under 30 minutes to over 150 hours. Typical “housekeeping” enzymes such as those of glycolysis, have t 1/2 values of over 100 hours.
