The energy contained in energy-yielding nutrients differs because the energy-yielding nutrients are composed of different types of chemical bonds. Dates In contrast to carbohydrates, lipids, and proteins, micronutrients are not sources of energy (calories), but they assist in the process as cofactors or components of enzymes (i.e., coenzymes). Depending on the type, a gram of carbohydrates provides different amounts of energy: Monosaccharides are directly absorbed by the small intestine into the bloodstream, where they are transported to the cells in need. The fat-soluble vitamins are A, D, E, and K. Vitamins are required to perform many functions in the body such as making red blood cells, synthesizing bone tissue, and playing a role in normal vision, nervous system function, and immune system function.

Non-starch polysaccharides, which are part of the dietary fibre group (although a few oligosaccharides such as inulin are also considered dietary fibre). When needed, for instance, between meals, at night, during spurs of physical activity, or during short fasting periods, our body converts glycogen back to glucose to maintain a constant blood sugar level. These are carbohydrates, lipids, proteins, water, vitamins, and minerals. If not used directly, the body converts glucose to glycogen, a polysaccharide like starch, which is stored in the liver and the muscles as a readily available source of energy. a starch with more branches is more easily broken down by enzymes and therefore more readily digestible than others, The amount of other nutrients in the food, such as fat, protein, and fibre.
