Pharmaceutical Enzymes are protein – biological catalysts that speed up chemical reactions in living organisms. These can be used as drugs, which have two important features that distinguish them from all the other types of chemical drugs. First, they bind and act on their targets with great affinity and specificity. And second, they are catalytic in nature converting multiple target molecules to the desired products. These two features make Pharmaceutical Enzymes specific and potent drugs that can accomplish therapeutic biochemistry in the body that small molecules cannot.
