Enzymes as Methods of Treatment for Human Conditions - Practically all biological reactions are orchestrated by enzymes. Although there are a few nucleic acids as enzymes, typically they are globular proteins. The function of any enzyme is to act as a catalyst, lowering the energy of activation and increasing the rate of a reaction. Enzymes increase reaction rates by magnitudes of as much as trillions. Such extreme control over reaction rates gives enzymes the ability to decide which reactions will or will not occur. Because of this fact many drugs used for therapeutic purposes act by inhibiting enzyme activities; thus, some enzymes are actually drug targets, and can be seen as methods of treatment for conditions such as hypertension, inflamm...   [tags: hypertension, HIV, inflammation] 1867 words
