Document Summary

Biology chapter 6: lipids, membranes and the first cells. General term for carbon-containing compounds that are found in organisms and are largely non-polar and hydrophobic. Do dissolve in liquids consisting of non-polar organic compounds. Do not dissolve in water because they have a significant hydrocarbon component and electrons are shared equally in carbon-hydrogen bonds, making them nonpolar. Are defined by their physical property (solubility) instead of their chemical structure. As a result, structure of lipids varies widely. Composed of three fatty acids that are linked to a three carbon molecule called glycerol. Form when a dehydration reaction occurs between a hydroxyl group of glycerol and the carboxyl group of a fatty acid. Glycerol and fatty acid molecules become joined by an ester linkage. Distinguished by hydrocarbon tail formed of isoprene subunits. An important component of plasma membranes in many organisms. Estrogen, progesterone and testosterone are examples of hormones derived from cholesterol: phospholipids.
