However ethanol is miscible with water so when a solution of lipid and ethanol is added to water the ethanol will combine preferentially to the water, leaving the ethanol to form tiny globules in the water. These globules then form a white emulsion. Ethanol extracts the lipid from the crushed solid sample. As ethanol is miscible with lipids no change is seen upon its addition to the solid and liquid samples. The lipid spontaneously comes out of solution when water is added and is dispersed as micelles (small droplets) throughout the solution of ethanol and water. ( This happens as hydrophobic portion of the lipid molecules project inwards and excludes the aqueous environment; the hydrophilic portion (-COOH) group faces the aqueous environement. ) A layer is formed at the top as lipids are less dense than water.
