Study Notes
Vitamins
- Vitamins are organic compounds found in food, essential for normal metabolism and health.
- They are required in small amounts for normal growth, development, maintenance, and reproduction.
- A deficiency of a specific vitamin can lead to a specific disease or syndrome.
- Vitamins are categorized into two groups: fat-soluble and water-soluble.
Fat-Soluble Vitamins (A, D, E, K)
- Fat-soluble vitamins are transported by lipoproteins and stored in the liver.
- They are not readily excreted and can accumulate in the body, leading to toxicity.
- Vitamin A (Retinol): Essential for vision, immune function, growth, and reproduction. Deficiency symptoms include night blindness, keratitis, rough hair coat, and reproduction problems.
- Vitamin D (Ergocalciferol and Cholecalciferol): Essential for calcium absorption and bone formation. Deficiency symptoms include rickets, osteomalacia, and poor eggshell formation.
- Vitamin E (Tocopherol): Protects cell membranes from damage and plays a role in reproduction. Deficiency symptoms include encephalomalacia and muscular dystrophy in livestock.
- Vitamin K (Menaquinone and Menadione): Essential for blood clotting. Deficiency symptoms include hemorrhages.
Water-Soluble Vitamins (B complex & C)
- Water-soluble vitamins are transported within fluid compartments of the body and are not stored.
- They are readily excreted via urine and generally non-toxic.
- Thiamin (B1): Essential for carbohydrate metabolism. Deficiency symptoms include polyneuritis in birds.
- Riboflavin (B2): Essential for energy production. Deficiency symptoms include curled toe paralysis in chicks.
- Niacin (B3): Essential for energy production and cell function. Deficiency symptoms include black tongue in chicks and dermatitis in pigs.
- Choline (B4): Essential for cell membrane function and fat metabolism. Deficiency symptoms include perosis (slipped tendon) in chicks.
- Pantothenic acid (B5): Essential for metabolism of carbohydrates, fats, and proteins. Deficiency symptoms include “goose stepping” in pigs.
- Pyridoxine (B6): Essential for protein metabolism and nerve function. Deficiency symptoms include dermatitis, alopecia, and convulsions.
- Biotin (B7): Essential for fatty acid synthesis. Deficiency symptoms include severe dermatitis.
- Folic acid (B9): Important for DNA synthesis and cell division. Deficiency symptoms include macrocytic anemia, and leucopenia.
- Cyanocobalamin (B12): Essential for red blood cell formation. Deficiency symptoms include pernicious anemia.
- Ascorbic acid (C): Essential for collagen synthesis, antioxidant, and immune function. Deficiency symptoms include scurvy and low immune resistance.
Differences between Fat-soluble and Water-soluble Vitamins
- Chemical Composition: Fat-soluble vitamins are composed of carbon, hydrogen, and oxygen. Water-soluble vitamins are composed of carbon, hydrogen, oxygen, and some contain nitrogen, sulfur, or cobalt.
- Transport: Fat-soluble vitamins are transported by lipoproteins. Water-soluble vitamins are transported by fluids within the body.
- Storage: Fat-soluble vitamins are stored in the liver. Water-soluble vitamins are not stored.
- Precursors: Fat-soluble vitamins have a provitamin form (e.g., carotene for vitamin A). Water-soluble vitamins do not have precursors.
- Excretion: Fat-soluble vitamins are excreted via feces. Water-soluble vitamins are excreted via urine.
- Absorption: Fat-soluble vitamin absorption is associated with fat absorption. Water-soluble vitamin absorption is a simple process.
- Toxicity: Fat-soluble vitamins can accumulate in the body and become toxic. Water-soluble vitamins are generally non-toxic.
