Document Summary
Organic molecules (macromolecules that do the work of the cell: carbohydrates, proteins, lipids, nucleic acids. Carbohydrates are used to provide energy, to store energy (glycogen), as dietary bre, and to provide carbon molecules that can be used to build other molecules. Glucose is an example of a monosaccharide, and it is a simple ring structure. Glycogen on the other hand is a polysaccharide. Lipids: they don"t have a core monomer, instead they are just de ned by their properties instead of their structures, lipids are de ned by their insolubility in water, examples include fatty acids, triglycerides, cholesterol, steroid hormones. They are the major energy storage in plants and animals, but more for animals. They also form the plasma membrane of cells that lets them be alive. Water is based on a polar covalent bond, because while it shares electrons with hydrogen, it doesn"t share them equally, making it slightly negative most of the time.
