Morphology

homocysteine = cysteine (semi-transparent) = homo + cysteine

Formally built from 'cysteine' with the combining form 'homo-' indicating a chemical variant, but the precise chemical difference is technical and not obvious to general learners.

Etymology

Homocysteine combines the prefix homo- meaning 'same' and cysteine, the name of an amino acid, so it literally means a 'same' form of cysteine. This helps you remember that homocysteine is an amino acid found in the blood and that high levels can affect heart health.
