7 Functional Groups

Amino Group

(—NH2) a functional group composed of nitrogen atom bonded to two hydrogen atoms and to the carbon skeleton. Can act as a base in solution, accepting a hydrogen ion and acquiring a charge of +1.

Sulfhydryl Group

(—SH) a functional group consisting of a sulfur atom bonded to a hydrogen atom.

Hydroxyl Carbonyl (ketone, aldehyde) Carboxyl Amino Group Sulfhydryl Phosphate Methyl

Hydroxyl Group

a functional group consisting of a hydrogen atom bonded to an oxygen atom by a polar covalent bond(—OH), which in turn is bonded to the carbon skeleton of a molecule. Molecules possessing this group are water soluble and called alcohols.

Phosphate Group

a functional group consisting of a phosphorus atom covalently bonded to four oxygen atoms and is important in energy transfer.

Carbonyl Group

a functional group present in aldehydes and ketones consisting of an oxygen atom double bonded to a carbon atom.

Carboxyl Group

a functional group present in organic acids consisting of a carbon atom double-bonded to an oxygen and also bonded to a hydroxyl group.(—COOH)
