theelin Biochem.
(ˈθiːlɪn)
[f. Gr. θῆλυς female + -in1.]
= œstrone.
| 1930 C. D. Veler et al. in Jrnl. Biol. Chem. LXXXVII. 357 The isolation of the crystalline hormone seems to justify the selection of a new name... Accordingly, we suggest the term ‘theelin’. 1935 [see oestrin]. 1936 Jrnl. Amer. Med. Assoc. 10 Oct. 1222/2 The term theelin has not been widely accepted. Ibid. 1223/1 The Council [on Pharmacy and Chemistry of the American Medical Association]..decided (1) to adopt the system of nomenclature based on the root estr-; (2) to retain theelin, theelol..as synonyms for..estrone, estriol. 1947 Sci. News IV. 137 Among the substances administered to plants..are: the juice of leaves subjected to the ‘right’ length of day; yeast extract;..theelin. |
So ˈtheelol [-ol] = œstriol.
| 1931 Doisy & Thayer in Jrnl. Biol. Chem. XCI. 642 We propose now, in view of the facts that the new substance is a trihydroxy compound and that it shows physiological and possibly chemical similarities to theelin, to name it theelol. 1936 [see above]. 1977 Martindale's Extra Pharmacopoeia (ed. 27) 1419/1 Oestriol. Estriol; theelol. |
