| oleiferous | Producing oil; as, oleiferous seeds. Origin: L. Oleum oil: cf.F. Oleifere. Source: Websters Dictionary (01 Mar 1998) |
| olein | <physiology> A fat, liquid at ordinary temperatures, but solidifying at temperatures below 0 deg C, found abundantly in both the animal and vegetable kingdoms (see Palmitin). It dissolves solid fats, especially at 30-40 deg C. Chemically, olein is a glyceride of oleic acid; and, as three molecules of the acid are united to one molecule of glyceryl to form the fat, it is technically known as triolein. It is also called elain. Origin: L. Oleum oil: cf. F. Oleine. Source: Websters Dictionary (01 Mar 1998) |
| oleo- | Oil. See: eleo-. Origin: L. Oleum (05 Mar 2000) |
| oleogomenol | <chemical, remedy> An ethereal oil obtained from a plant, Melaleuca viridiflora; the chief constituent is cineole. It has germicidal action, is free from irritating properties, and has been used in chronic inflammations of the pulmonary mucous membrane and as a vermifuge. Synonym: oleogomenol. Origin: Gomen, a locality in New Caledonia, + L. Oleum, oil (05 Mar 2000) |
| oleogranuloma | A nodule or focus of granulomatous inflammation (usually of the foreign-body type) in association with lipid material deposited in tissues, e.g., after the injection of certain oils. See: paraffinoma. Synonym: eleoma, oil tumour, oleogranuloma, oleoma. (05 Mar 2000) |
| oleograph | 1. <chemistry> The form or figure assumed by a drop of oil when placed upon water or some other liquid with which it does not mix. 2. A picture produced in oils by a process analogous to that of lithographic printing. Origin: L. Oleum oil + -graph. Source: Websters Dictionary (01 Mar 1998) |
| oleoma | A nodule or focus of granulomatous inflammation (usually of the foreign-body type) in association with lipid material deposited in tissues, e.g., after the injection of certain oils. See: paraffinoma. Synonym: eleoma, oil tumour, oleogranuloma, oleoma. (05 Mar 2000) |
| oleomargarine | 1. A liquid oil made from animal fats (especially. Beef fat) by separating the greater portion of the solid fat or stearin, by crystallization. It is mainly a mixture of olein and palmitin with some little stearin. 2. An artificial butter made by churning this oil with more or less milk. Oleomargarine was wrongly so named, as it contains no margarin proper, but olein, palmitin, and stearin, a mixture of palmitin and stearin having formerly been called margarin by mistake. Origin: L. Oleum oil + E. Margarine, margarin Alternative forms: oleomargarin. Source: Websters Dictionary (01 Mar 1998) |
| oleometer | <chemistry> An instrument for ascertaining the weight and purity of oil; an elaiometer. Origin: L. Oleum oil. Source: Websters Dictionary (01 Mar 1998) |
| oleone | <chemistry> An oily liquid, obtained by distillation of calcium oleate, and probably consisting of the ketone of oleic acid. Origin: L. Oleum + -one, 1. Source: Websters Dictionary (01 Mar 1998) |
