the family of steroid compounds can be chemically modified for biochemical and other applications. Derivatives of cholic acid with multiple methacrylate groups can be prepared by the use of methacrylic acid, methacryloyl chloride and methacryloyl anhydride as the acylating agents. The hydroxyl groups of cholic acid methyl ester and cholic acid ethylene glycol ester have been selectively acylated by
