During staining, the dye leaves the solvent because of its high solubility in lipids than solvent. This happens because the fatty acids derived from triglycerides in the cytoplasm enter the mitochondria and become involved in the Krebs cycle through the beta oxidation pathway.

Alternatively, the Brown Bag test can also be used to identify lipids due to the oily nature of hydrocarbon chains. A red-stained oil layer will separate out and float on the water surface if fat is present. Only a faint yellow stain is produced during the grease spot test on egg yolk because as the water evaporates from the filter paper the plant pigment in the yolk, xanthophylls, colours the paper preventing the permanent translucent stain from being seen. Give an example. Maria Berger. Take 0.5 ml ether or chloroform in a test tube and add 0.5 ml sampledrop by drop till the sample is fully dissolves. Most butters contain about 80%fat.
