Abstract This experiment investigated the kinetics of the enzyme glycogen phosphorylase b which is important to metabolism. AMP is an allosteric activator of the enzyme because it converts glycogen phosphorylase b from its T state to the R state which is the active form. Caffeine is an inhibitor because it binds the nucleoside inhibitor site. When it binds this site‚ it stabilizes the inactive T state and blocks the catalytic site which needs to be open for enzyme activity to occur. The glycogen

Introduction: Acetaminophen is a commonly used analgesic‚ which is essentially just a medicine that relieves pain (Prescott‚ 2000). Acetaminophen is created by synthesizing p-Aminophenol with Acetic anhydride. This reaction occurs when the amine group of the p-aminophenol is acetylated by the acetic anhydride. The resultant is an amide functional group (Ellis‚ 2002). However‚ the product that is obtained from this product is a crude solid which cannot be used as an analgesic and therefore the crude
