Root Explanation

The word 'dopa' originates from the term 'dopamine', which is derived from 'dopa' (from the chemical name '3,4-dihydroxyphenylalanine'). The prefix '3,4-' indicates the positions of the hydroxyl groups on the phenylalanine structure, while 'dihydroxy' refers to the presence of two hydroxyl groups. The root 'phenylalanine' comes from 'phenyl' (a type of hydrocarbon) and 'alanine' (an amino acid). Thus, 'dopa' refers to a specific amino acid derivative involved in the synthesis of dopamine, a neurotransmitter.

Memory Tip

Think of 'dopa' as a key building block ('phenylalanine') that has two hydroxyl groups, which helps you remember its role in creating dopamine, a crucial neurotransmitter.
