Final answer:
Vitamins are divided into two categories: fat-soluble, which includes vitamins A, D, E, and K, and water-soluble, which includes the B complex vitamins and vitamin C. Fat-soluble vitamins are stored in the body's fatty tissue, while water-soluble vitamins must be replenished regularly.
Step-by-step explanation:
Vitamins are classified into two groups: fat soluble vitamins and water soluble vitamins. The fat-soluble vitamins include vitamins A, D, E, and K, and they are important for various physiological functions such as vision, bone health, antioxidative activities, and blood clotting. On the other hand, water-soluble vitamins, which include the B complex vitamins and vitamin C, are typically needed for the formation of coenzymes and are involved in a wide range of metabolic processes, including energy production and the synthesis of neurotransmitters.
