Kendra Keilen 3/6/2016 6th hour Chemistry in Everyday Life Medicine Drugs are chemicals of low molecular masses. These connect with macromolecular goals and produce a biological response. When the biological response is healing and useful, these chemicals are called medicines and are used in diagnosis, prevention and treatment of diseases. Medicines usually interact with biomolecules such as carbohydrates, lipids, proteins and nucleic acids. These are called target molecules or drug targets. Also, compounds used as medicines are most often organic compounds, which are often divided into the broad classes of small organic molecules (atorvastatin, fluticasone, clopidogrel) and "biologics" (infliximab, erythropoietin, insulin glargine). In particular, medicinal chemistry in its most common disguise—focusing on small organic molecules—encompasses synthetic organic chemistry and aspects of natural products and computational chemistry in close combination with chemical biology, enzymology and structural biology, together aiming at the discovery and development of new therapeutic agents.
