Choleic Acid - Cholesan

Japanese: コレイン酸 - コレインサン
Choleic Acid - Cholesan

A general term for molecular compounds of deoxycholic acid and various compounds. In particular, molecular compounds with stearic acid, palmitic acid, or oleic acid are called choleic acid in the narrow sense. The component that combines with deoxycholic acid is called the alcoholic component, and these components can be fatty acids and their esters, alcohols, ethers, hydrocarbons, and alkaloids. Up to eight molecules of deoxycholic acid can combine with one molecule of the alcoholic component, and the stability of the molecular compound and its solubility in solvents also change in various ways. By utilizing this property, deoxycholic acid, which is soluble in water, can be made insoluble by converting it to choleic acid. Choleic acid in the narrow sense is present in bile. Colorless crystals. Insoluble in water. Can be recrystallized from alcohol or aqueous acetic acid.
