Morphology

cystathionine = cyst + thion + ine

A specialized chemical name formed from technical combining forms (e.g., 'cyst-' and 'thio-') and the amino-acid suffix '-ine', which is not derivable by an average B1 learner from the component meanings.

Etymology

Cystathionine comes from parts of older chemical names: cysteine, a small sulfur amino acid, thio- meaning 'sulfur', and the ending -ine which marks amino acids. So, cystathionine is an amino acid related to cysteine and methionine and contains sulfur, which explains its role in the body's processing of these amino acids.
