/ɡl(j)uːtəˈθʌɪəʊn/

1921 F. G. Hopkins in Biochem. Jrnl. 15 297 Provisionally, for easy reference, the name Glutathione will perhaps be admissible. It leaves a link with the historic Philothion, has the same termination as Peptone, which has long served as a name for the simpler peptides, and is a sufficient reminder that the dipeptide contains glutamic acid linked to a sulphur compound.

1949 H. W. Florey et al. Antibiotics II. xxi. 812 Glutathione and thiothreonine antagonized the anti-bacterial action of penicillin.

1969 Nature 11 Oct. 117/1 The tripeptide glutathione is an almost universal constituent of functioning biological systems.
