Study Notes

Vitamins: Structures, RDA, Sources, Deficiencies

Vitamin A:
- Involved in reproductive functions, growth, and development
- Crucial for vision (maintaining healthy light transduction cells)
- Essential for proper calcium and phosphorus metabolism
- Part of RNA formation
- Deficiency can lead to reproductive issues, vision problems, and poor bone health
- Sources include various fruits and vegetables
Vitamin D:
- Important for calcium and phosphorus balance in blood
- Plays a role in bone development and health
- Deficiency might cause severe growth retardation in children and osteomalacia (softening of bones) in adults
- Potential for skeletal deformities
- Sources: dietary sources, sunlight
Vitamin E:
- Antioxidant, protecting tissues from free radicals
- Aids in red blood cell creation
- Prevents oxidation of lipid-based cell membranes
- Sources include almonds, spinach, wheat, asparagus, and other plant-based foods
Vitamin K:
- Crucial for protein creation, aiding in blood clot formation
- Regulates calcium levels
- Vital for wound healing and stopping bleeding
- Sources include spinach, Brussels sprouts, asparagus, broccoli, and green chilies
- Deficiency can lead to excessive bleeding
B Vitamins (Table):
- Thiamin (B1): Essential for converting sugar to energy, supports healthy mucous membranes
- Riboflavin (B2): Key for oxidation-reduction reactions, maintaining healthy skin, vision, growth, and red blood cells
- Niacin (B3): Converts carbohydrates, proteins, and fats into energy; supports digestion and nerve function
- Pantothenic Acid (B5): Helps break down macronutrients for energy; crucial for various bodily functions
- Pyridoxine (B6): Aids protein, carbohydrate, and fat metabolism; important during pregnancy and for cell production
- Folate (B9): Required for red blood cell production; prevents anemia, low birth weight and prematurity
- Cobalamin (B12): Supports red blood cell health and a healthy central nervous system; works with B9; crucial for proper metabolism
- Biotin (B7): Essential for fatty acid and glucose metabolism; critical for the body's energy production
- These B vitamins work together with other B vitamins, carbohydrates, proteins and fats to provide energy.
Vitamin C:
- Regulates the immune system, relieves muscle soreness
- Involved in collagen and norepinephrine production
- Acts as an antioxidant, boosts white blood cell activity
- Promotes healthy skin, teeth, and bones
- Sources include citrus fruits, amla, and leafy vegetables
