This chapter relates how the elements hydrogen, oxygen, carbon, and nitrogen—dominating in all life on the Earth—make up more than 96% of our body weight. Carbon is the key component of organic molecules, in which it is combined with about 20 other elements to form the basic building blocks of our bodies. The four main categories of organic molecules—carbohydrates, lipids, proteins, and nucleic acids—carry and store energy, form building blocks of the cells, regulate the body’s chemistry, and help store the information from which cell structure and function are derived. A network of metabolic pathways releases energy to the body when needed and stores surplus energy for later use. This chemical machinery, powered by the plants and animals that we consume, constantly works to keep us going
