LIPIDS AND PROTEIN TESTING IN FOODS
All living things contain organic macromolecules: Lipids, proteins, carbohydrates and nucleicacids. Characteristic for these organic molecole is that they are made up of only a small number of elements: carbon, hydrogen, oxygen, and to smaller amounts nitrogen, phosphorus and sulfur.
They are called "macromolecules" because they are very large, containing long chains of carbon and hydrogen atoms and often consists of repeating smaller molecules bonded together in a repeating pattern (polymers).
