Flashcards
Night blindness and Vitamin A deficiency
Night blindness and Vitamin A deficiency
A deficiency of vitamin A (retinol) leads to night blindness due to impairment of rhodopsin protein production.
Scurvy and Vitamin C deficiency
Scurvy and Vitamin C deficiency
Vitamin C (ascorbic acid) is crucial for collagen production, and a deficiency can lead to scurvy, characterized by various symptoms like swollen gums, easy bruising, and brittle hair.
Beriberi and Vitamin B1 deficiency
Beriberi and Vitamin B1 deficiency
Vitamin B1 (thiamine) is essential for carbohydrate and protein metabolism, and a deficiency can result in beriberi, which affects the heart, circulatory system, nerves, and muscles.

Study Notes
Vitamin A (Retinol)
- Derived from beta-carotene.
- Stored in the liver.
- A deficiency causes rhodopsin protein deficiency, leading to "night blindness."
- Deficiency affects the epithelium, causing dry hair, scaly skin, and brittle nails.
Vitamin B1 (Thiamine)
- Crucial for carbohydrate and protein metabolism, particularly in high-carbohydrate diets.
- Involved in neurotransmitter production and myelin production.
- Differences in nutritional value exist between milled and unmilled rice.
- Deficiency can lead to beriberi, a disease that presents as either "wet" (affecting the heart and circulatory system) or "dry" (affecting nerves and muscles).
Vitamin C (Ascorbic Acid)
- Essential for collagen production.
- Historically, deficiency was a problem for sailors on long journeys, manifesting as scurvy.
- Symptoms of scurvy include swollen, bloody gums, loose teeth, bulging eyes, severe bruising, and scaly, dry, brownish skin.
- Deficiency also leads to very dry, curly hair that breaks easily.
- Deficiency is observed in populations during late winter/early spring and those with low income and poor diet.
Vitamin D (Calcitriol)
- Stimulates calcium absorption in the small intestine.
- Necessary for bone deposition.
- Deficiency can lead to osteomalacia (poorly mineralized bones) and rickets.
