Document Summary

They have numerous carbon to hydrogen covalent bonds. Electrons are shared equally across the bonds. Lipids brought together do not form polymers. Starts as an amino acid and then becomes a protein which is a more complex polymer. We can not polymerize an individual lipid molecule. 3 most important types of lipids found in cells. Composed of 3 fatty acids linked to glycerol (which is sweet tasting) A family of lipids with a distinctive four ring structure. Cholesterol is an important steroid in mammals. A lot of hormones are steroids, such as testosterone. Consist of a glycerol linked to a phosphate group and to wither 2 chains of isoprene or 2 fatty acids. Fatty acid tails are a great source of potential energy because the electrons are being shared equally, but they are hydrophobic. To make them more soluble in water, you add a phosphate group, which makes it polar and hydrophilic.
