Document Summary
Lipid is a catchall term for carbon-containing compounds that are found in organisms and are largely nonpolar and hydrophobic (do not dissolve readily in water) Lipids do dissolve, however, in organic solvents consisting of nonpolar compounds like benzene. Isoprene"s- consists entirely of carbon atoms bonded to hydrogen atoms. Structural formula of a chain of linked isoprene"s. Functions: pigments, scents to vitamins, precursors of sex hormones, important building blocks for other complex lipids. Hydrocarbons are molecules that contain only carbon and hydrogen. Lipids are mostly hydrophobic because they have a significant hydrocarbon component. Fatty acid- a simple lipid consisting of a hydrocarbon chain bonded to a carboxyl functional group. Key building blocks of important lipids found in organisms. Hydrocarbon chains that consist of only single bonds between the carbons. Waxes are lipids with extremely long saturated hydrocarbon chains. Waxes: saturated lipids with extremely long hydrocarbon tails. One of more double bonds exist in the hydrocarbon chains.
