Which specific vitamin is alternatively designated as Biotin?
Show answer Hide answer
Answer: D. vitamin B-7
Explanation
Vitamin B-seven is the official numerical designation assigned to the water-soluble compound known as biotin. It acts as a critical coenzyme for carboxylase enzymes involved in human fatty acid and amino acid metabolism. This vitamin is essential for maintaining healthy metabolic pathways and cellular energy production. The B-complex vitamins are a group of water-soluble compounds that play vital roles in cell metabolism. Human intestinal bacteria can synthesize small amounts of biotin, supplemented by dietary intake from foods. Nutritional science classifies vitamins as essential micronutrients that the body cannot synthesize in adequate amounts.
Dietary supplements often include biotin because it supports healthy hair, skin, and nail keratin production. Deficiency in vitamin B-seven can lead to dermatological issues, hair loss, and neurological symptoms. Food sources rich in biotin include egg yolks, nuts, seeds, and various leafy green vegetables. Vitamin B-three is chemically known as niacin, which functions in cellular respiration and DNA repair. Vitamin B-four is an obsolete historical term and is not recognized as an essential human vitamin. Vitamin B-five is known as pantothenic acid, which is vital for synthesizing coenzyme A molecules.
