     E[rnst]. Schulze (Berl. Ber., 12, 249) has determined the specific rotation of isocholesterine (found by the author, associated with cholesterine, in the fat from sheep’s wool). This substance is dextro-rotatory, whereas cholesterine is laevo-rotatory. An etherial solution of isocholesterine, containing 6.453 gms in 100 cc, showed in the 200 mm tube of a Soleil-Ventzke polariscope, a rotation of 22°; a solution of half the strength rotated 11.25°. A solution of another preparation, containing 7.344 gms in 100 cc, showed a rotation of 25.5°. From these data, the author deduces for isocholesterine the specific rotation [a]_b = + 60°.

   • 1890, J[ohn] J[ames] Hummel, “Wool”, in [William Edward] Ayrton, R[ichard] Wormell, editors, The Dyeing of Textile Fabrics (Manuals of Technology), London, Paris, Melbourne, Vic.: Cassell & Company, Limited, part “Fibres”, section 35, “Wool-fat”, page 38:

     Further analysis has shown that the soluble portion consists mainly of the alcoholic and fat-like body cholesterine, together with isocholesterine, each in the free state, and probably also of compounds of both these bodies with such organic acids as acetic acid. The insoluble portion consists essentially of compounds of cholesterine and isocholesterine with oleïc acid, and in lesser amount with solid fatty acids, e.g., stearic acid and hyæna acid.

     Besides cholesterine crude lanolin contains isocholesterine combined with fatty acids, glycerides of the lower fatty acids, cerylcerotate and homologous compounds and the volatile capric and caproic acids.

   • 1896, Harry W. Clark, “Experiments upon the Purification of Sewage and Water at the Lawrence Experiment Station, During the Year 1895”, in Twenty-Seventh Annual Report of the State Board of Health of Massachusetts, number 34, Boston, Mass.: Wright & Potter Printing Co., […], section “Filtration of Sewage”, subsection “The Disposal of Waste Liquors from Industrial Works”, subsubsection “Wool Scouring”, page 470:

     The soluble portion consists mainly of cholesterine and isocholesterine, together with compounds of these bodies with organic acids. The insoluble portion consists mainly of cholesterine and isocholesterine with oleic and fatty acids.
