aldehyde
C=O

carbonyl group/ in the middle of the skeleton structure (characterizes ketone)

may be a structural isomer of a ketone
thiol
S-H

forms disulfide bonds

characterized by the presence of sulfhydryl group

also helps stabilize proteins by forming covalent cross-link within or between protein molecules
amine
NH2

acts as a base
