Study Notes
Vitamins Overview
- Vitamins are organic compounds that cannot be synthesized by the human body and are essential for various metabolic processes.
Vitamin A
- Primarily obtained from animal sources such as liver, dairy products, and fish, as well as from beta-carotene, a precursor found in dark green and yellow vegetables.
- Plays a crucial role in cell growth and differentiation, particularly in the development and maintenance of epithelial tissues.
- Essential for vision, especially in low light conditions, as it helps to regenerate rhodopsin, a light-sensitive pigment in the retina.
- Deficiency in epithelial tissues leads to keratinization, a process characterized by the abnormal proliferation of keratin, a protein found in skin and mucous membranes.
- Plays a role in reproduction, specifically in the development and maintenance of sperm and egg cells.
Fat-Soluble Vitamins
- Include vitamins A, D, E, and K, which are stored in the body's fatty tissues and liver.
- Can accumulate in the body, leading to toxicity if consumed in excess.
- True statement about fat-soluble vitamins: they require the presence of bile salts for absorption.
Vitamin D
- Synthesized from cholesterol when the skin is exposed to sunlight.
Vitamin Deficiency
- Results in a range of health problems, depending on the specific vitamin deficiency.
- Can lead to impaired growth and development, weakened immune systems, and increased susceptibility to disease.
Vitamin Sources
- Most vitamins are obtained from the diet, with a variety of foods providing different vitamins.
- Foods rich in vitamins include fruits, vegetables, whole grains, lean proteins, and dairy products.
