text: what is molecular science? what is the salary per year? what training you need? molecular science is the study of molecules: another words what their properties are,  heat capacity, intereactions, ph sensitivity, pressure,  and what not. now it depends who you ask, whether its a biologist or a chemist what a molecule really is. if you ask a biologist they may focus on protein, carbohydrate, and lipid interactions  where as if your a chemist you are just focused on monomeric type molecules.
