An organic compound structurally derived, theoretically or practically, from ammonia by replacing one, two, or all three hydrogen atoms with hydrocarbon radicals (alkyl or aryl). Depending on the number of hydrogen atoms replaced, amines are classified into primary, secondary, and tertiary, possessing basic character and playing crucial biological and industrial roles (ranging from amino acids and neurotransmitters to dyes and pharmaceuticals).
