I think we will have;
Alcohol is a highly polar and may act as a weak acid, functional group is OH
Carboxylic acid; acts as an acid, the functional group is COOH
Aldehyde; may be a structural isomer of a ketone, functional group C=O
Thiol; it forms disulfide bonds since it has a functional group S-H
Amine, this may act as a base, due to the functional group NH2
Organic phosphate ;it contributes a negative charge considering its functional group PO4
