- One of the following is not a structural lipid. Sphingomyline Triglycerides Phosphatidylcholine O. All choices are structural lipids CholesterolThis is fill in the blanks ( please check my answers which are the ones underlined) There are five basic types of macromolecules. Those which are used mostly for energy in the body and are made of ring-like structures are called carbohydrates. A single ringed molecule is a monosaccharide, while a molecule with 2 rings is called a disaccharide. Those made by assembling many rings into chains are called covalent bonds. This macromolecule is made only from the elements Carbon, Hydrogen, and Oxygen. Another macromolecule made only from these elements lipids. The simplest molecule in this category is called a fatty acid. Three of these can combine with a molecule called glycerol to form a triacylglycerol. A special kind of this macromolecule that includes phosphate and nitrogen is used in cell membranes is called phospholipids. Testosterone and estrogen are another special category of this macromolecule, called hormones. A third macromolecule is based on amino acids. These are made of the…Draw a lipid structure.
