Slowly add the thiosulphate solution again till it becomes colourless. Simple lipids are esters of fatty acids with various alcohols, e.g., fats (esters of fatty acids with glycerol) and waxes (esters of fatty acids with higher molecular weight of monohydric alcohols). Answer. This test is given by the substances containing primary and secondary alcohol groups. Alternatively, hydrogen peroxide has been quantified by formation of chelate complex with quadrivalent titanium and xylenol orange. Assays have been developed in which cholesterol oxidase obtained from the bacterium Nocardia erythropolis is used to convert cholesterol into cholest-4-en-3-one with the formation of Hydrogen peroxide.
