Vitamins
Vitamins release energy from carbohydrates , proteins , and fat
Carbohydrates provide a quick source of energy for the body that proteins do not.
We get most of our food energy from carbohydrates. Carbohydrates are the body's preferred source of energy and are broken down into glucose to fuel our cells. Proteins are essential for growth and repair of tissues, but they are not as efficient as carbohydrates in providing energy for the body.
Protein, fat, and carbohydrates provide energy for the body. Carbohydrates provide bodily energy the quickest. Fats/Lipids are stored as body fat for later/emergency usage. Proteins usually are used to create bones, tissue, and muscle - they don't really provide energy.
Energy is obtained by proteins/carbohydrates in your body.
The three sources are carbohydrates, proteins and lipids. There are more like vitamins, minerals, and water.
metabolism
Enzymes to break down proteins and carbohydrates, absorption in the gut (intestines etc)
Carbohydrates
Water, vitamins, and minerals do not supply any kilocalories of energy to the body. However, they are vital in the processes that release energy from carbohydrates, proteins, and fats.
Carbohydrates provide the most readily available energy as they are efficiently broken down into glucose, which is the body's primary source of energy. Unlike lipids, nucleic acids, and proteins, carbohydrates can be quickly metabolized to produce immediate energy.
Proteins do provide energy, but in a small amount. Proteins are body building materials. Carbohydrates are a good source of energy.
