Definitions of large and small molecules......fascinating for nerds.
Pharmaceutical Drug Development (Small Molecules / Large Molecules) ... Large molecules, or biologics, are classified as proteins having a therapeutic effect. In contrast to small molecule drugs, most large molecule drugs are complex and composed of more than 1,300 amino acids and are identical versions of human proteins.
Compared to biologics, small molecule drugs are relatively simple chemical compounds and can be manufactured by chemical synthesis. These compounds are typically comprised of 20 to 100 atoms and have a molecular mass of less than 1000 g/mol or 1 kilodalton [kDa]
