WebEnzyme inhibition can be categorized in three types: competitive, noncompetitive, and uncompetitive. Competitive inhibition happens when a compound similar to the substrate is present and competes with the substrate for the active sites of the enzyme obstructing the access of substrate to the active site, thus slowing down the reaction. 37,38 http://chemistry.elmhurst.edu/vchembook/573inhibit.html
