Question

Vitamin B7 is also known as:

• A. Niacin
• B. Pantothenic Acid
• C. Pyridine
• D. Biotin

Hint:

Biotin is found in various foods, including eggs, nuts, legumes, and whole grains. While deficiency is rare, it can occur in people with certain medical conditions or those consuming excessive amounts of raw egg whites (which contain avidin, a protein that binds to biotin and inhibits its absorption).

Answer 1

The Correct Option is D

Vitamin B7, commonly referred to as Biotin, is an essential water-soluble vitamin crucial for several metabolic processes in the body.

Biotin plays a vital role in:

• Energy production: It acts as a coenzyme in various metabolic pathways, including gluconeogenesis (the production of glucose from non-carbohydrate sources), fatty acid synthesis, and amino acid metabolism.
• Cell growth and development: Biotin is essential for the synthesis of DNA and RNA, which are crucial for cell growth and repair.
• Skin, hair, and nail health: Biotin deficiency can lead to brittle nails, hair loss, and skin rashes.

Other B vitamins:

• Niacin (Vitamin B3): Plays a crucial role in energy production and cellular metabolism. Deficiency can lead to pellagra, characterized by dermatitis, diarrhea, and dementia.
• Pantothenic Acid (Vitamin B5): Involved in the synthesis of coenzyme A, which is essential for energy production and various metabolic pathways. Deficiency is rare but can cause fatigue, nausea, and vomiting.
• Pyridine: Not a vitamin. Pyridine is an organic compound used as a solvent and in the synthesis of various chemicals.
