Metabolism catabolism

The hypothesized mechanism by which a decrease In HL activity leads to an increase in HDL cholesterol, or the HDL2 subfraction, is illustrated in figure 2. As HL activity decreases, less HDL2 is metabolized/catabolized by the liver, leading to an increase In the concentration of this particle in the plasma. This mechanism is as yet speculative. 

Papaverine inhibits cavernosal phosphodiesterase, thereby decreasing metabolic catabolism of cAMP in cavernosal tissue. As a result of the enhanced tissue levels of cAMP, smooth-muscle relaxation occurs. Cavernosal sinusoids fill with blood and a penile erection results. ...

For years, there has been ample evidence for chemical transformations of D-fiuctosamine derivatives upon their exposure to bacterial,fungal, " plant, and animal cells. These observations imply a number of enzymatic reactions that provide for metabolism/catabolism of the Amadori compounds in vivo. Several distinct groups of enzymes that recognize D-fiuctosamines as the substrates have been so far identified.
