Substituted phenethylamines carry additional chemical modifications at the phenyl ring, the sidechain, or the amino group:
Amphetamines are phenethylamines carrying an alpha-methyl (�-CH3) group at the sidechain carbon atom next to the amino group.
Catecholamines are phenethylamines carrying two hydroxy groups in positions 3 and 4 of the phenyl ring. Examples are the hormones and neurotransmitters dopamine, epinephrine (adrenaline), and norepinephrine (noradrenaline).
The aromatic amino acids phenylalanine and tyrosine are phenethylamines carrying a carboxyl group (COOH) in alpha position.
