Final answer:
Vitamins are categorized based on their solubility into fat-soluble and water-soluble vitamins. Fat-soluble vitamins include A, D, E, and K, which are stored in the body's fatty tissue, while water-soluble vitamins include the B-complex vitamins and vitamin C, which typically act as coenzymes. The correct option is B. solubility
Step-by-step explanation:
Vitamin Classification
Vitamins are organic substances required in minute quantities in the diet to maintain normal physiological functions of the body. They are classified based on solubility, dividing them into two main categories: fat-soluble and water-soluble vitamins. Fat-soluble vitamins, which include vitamins A, D, E, and K, contain a high proportion of hydrocarbon structural components and are nonpolar.
These vitamins are stored in the body's fatty tissue and the liver and are important for various physiological functions. Water-soluble vitamins, on the other hand, include the B-complex vitamins and vitamin C, which contain large numbers of electronegative oxygen and nitrogen atoms, allowing them to engage in hydrogen bonding with water and typically act as coenzymes or are required for the synthesis of coenzymes.
An example of a water-soluble vitamin is vitamin C, while vitamins like vitamin D and vitamin K are fat-soluble and essential for maintaining a stable nervous system and blood clotting, respectively. The correct option is B. solubility
