Unformatted text preview: book. What is this special group called? Is it polar or nonpolar? Carboxyl group Components of Triglycerides (Fats): Glycerol + Fatty Acids SoHow much water is made when you make a triglyceride? Type of Reaction? Glue your copy of a triglyceride molecule onto the left side of your book. Circle where water is removed. Saturated Fats All carbons are single-bonded to hydrogens (saturated with hydrogens) Ex. Butyric Acid *Most animal fats *Solid at room temperature *Healthy? Unsaturated Fats C=C double bonds in the fatty acids (all the carbons are NOT saturated with hydrogens) Ex. Oleic Acid *plant and fish fats *vegetable oils *liquid at room Monounsaturated Polyunsaturated Multiple C=C double bonds in the fatty acids Ex. Linoleic Acid...
