Study Notes
Definition of Vitamins
- Organic compounds essential for normal growth, maintenance, and reproduction.
- Required in minute amounts for proper nutrition and health.
- Distinct from other food substances as they do not form tissue structures like proteins.
- Unlike carbohydrates and lipids, vitamins do not provide energy through degradation.
- Several B complex vitamins act as coenzymes in energy transformation reactions.
Differences from Hormones
- Vitamins are not produced within the organism.
- Most vitamins must be obtained through the diet.
Classification of Vitamins
- Vitamins are classified based on solubility into two main groups:
Fat-soluble Vitamins
- Vitamins that dissolve in fats; stored in body tissues.
- Include:
- Vitamin A
- Vitamin D
- Vitamin E
- Vitamin K
Water-soluble Vitamins
- Vitamins that dissolve in water; generally not stored in the body.
- Include:
- Vitamin C (ascorbic acid)
- B complex vitamins, which consist of:
- Vitamin B1 (thiamine)
- Vitamin B2 (riboflavin)
- Vitamin B3 (Niacin or nicotinic acid)
- Vitamin B5 (Pantothenic acid)
- Vitamin B6 (pyridoxine)
- α-Lipoic acid
Definition of Vitamins
- Organic compounds essential for normal growth, maintenance, reproduction, and overall health.
- Required in minute amounts, distinguishing them from macronutrients.
- Do not form tissue structures like proteins; do not provide energy as carbohydrates and lipids do.
- Several B complex vitamins act as coenzymes in energy transformation processes within the body.
- Most vitamins cannot be synthesized by the body; therefore, they must be obtained through diet.
