Study Notes

Vitamin Functions and Deficiencies

Vitamin E (tocopherol) acts as an antioxidant, protecting cells from damage.
Vitamin D deficiency in adults causes osteomalacia, a condition characterized by softening of bones.
Vitamin K is essential for blood clotting and preventing excessive bleeding.
Vitamin E deficiency can lead to neuromuscular problems, including muscle weakness and vision impairment.
Vitamin E is a mixture of eight different compounds, including tocopherols and tocotrienols.
Fat-soluble vitamins, such as vitamins A, D, E, and K, are stored in the body's liver, fatty tissue, and muscles.
The K vitamins play a crucial role in blood clotting and bone health.
Ascorbic acid, also known as vitamin C, is found in citrus fruits and plays a key role in collagen synthesis.
Ascorbate helps to maintain healthy skin, bones, and connective tissue.
Vitamin K is necessary for the production of clotting factors in the liver and bone mineralization.
Vitamin C is responsible for the hydroxylation of proline residues in collagen, which gives collagen its strength and structure.
Scurvy results from a deficiency in vitamin C.
Vitamin D absorption is enhanced by the presence of dietary fat.
Vitamin D deficiency in children causes rickets, a condition characterized by softening of bones.
Excess water-soluble vitamins, such as vitamin C and B vitamins, are flushed out of the body through urine.
Vitamin D is primarily responsible for regulating calcium and phosphorous homeostasis.
The major natural source of vitamin D is sunlight exposure, which triggers its synthesis in the skin.
Vitamin E and vitamin C are classified as antioxidants, protecting cells from oxidative damage.
