Three categories of lipids are. 14. Triglycerides are made up of Triglycerides provide (more/less) energy than carbohydrates. 15. A triglyceride with all C-C single bonds is said to be (saturated/unsaturated). It is (liquid/solid) at room temperature. 16. A triglyceride with at least one C=C double bond is said to be (saturated/unsaturated). It is (liquid/solid) at room temperature. 17. (saturated/unsaturated) triglycerides build up an block arteries. 18. A lipid composed of glycerol, 2 fatty acids and phosphate is a. The phosphate groups make up the (hydrophilic/hydrophobic) heads which are (polar/nonpolar). The fatty acids make up the (hydrophilic/hydrophobic) tails which are (polar/non polar). 19. Cell membranes are made up of a with (hydrophilic/hydrophobic) heads on the outside and (hydrophilic/hydrophobic) tails on the inside. This structure gives the cell membranes its function of. 20. Lipids consisting of 4 interlocking rings with added functional groups that give certain properties to the lipid are called.
