Respuesta :
Some of the crucial functional groups in organic compounds are the hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl groups. The formation of molecules including DNA, proteins, carbohydrates, and lipids depends heavily on these groups.
What are the four functional groups?
A functional group is an atom or group of atoms that have been linked in a particular way and are in charge of giving organic molecules their distinctive chemical properties. Examples include hydroxyl (-OH), aldehyde (-CHO), ketonic (-CO-), and carboxylic acid (-COOH) groups.
