Question

Pharmaceutical is an industry that relies heavily in chemistry in order for them to design and make drugs of all sorts. Identifying a molecule with a specific medicinal effect like lowering cholesterol or killing bacteria takes time collecting immense “libraries” or molecules which could lead to eventually be tested for their usefulness in treating disease in animals and people. How is chemical reaction play a role in the medicine people and animals take? You can use examples to answer the question.

Answer 1

The drug only works by chemical reaction. The drug reacts with a target molecule which for example could be inhibiting an enzyme involved in the bio-synthetic pathway of cholesterol (statin, cholesterol drug) or cell wall synthesis of a bacterium (antibiotic).
