Which type of organic compound includes substances that the body cannot synthesize and must obtain from the diet?

Vitamins are crucial organic compounds that the body cannot synthesize on its own, making it essential to obtain them through the diet. They play a vital role in numerous bodily functions, including immune response, energy production, and the maintenance of healthy skin and nerves. Each vitamin serves specific functions and is required in varying amounts; for example, vitamin C helps with the healing of wounds and the functioning of the immune system, while B vitamins are integral in energy metabolism.

The body’s inability to produce vitamins highlights their importance in our daily nutrition. Unlike other nutrients such as proteins, carbohydrates, and fats, which the body can create from other compounds or sources, vitamins must be ingested because they perform unique biochemical roles that are not replaceable. Consuming a balanced diet rich in fruits, vegetables, whole grains, and proteins ensures an adequate intake of these essential vitamins.
