What is a primary function of biotin in the human body?

Biotin plays a crucial role in the metabolism of fatty acids, proteins, and carbohydrates, making it essential for energy production and overall metabolic functions in the human body. It acts as a coenzyme for carboxylase enzymes, which are involved in various metabolic pathways, including gluconeogenesis (the production of glucose from non-carbohydrate sources), fatty acid synthesis, and the metabolism of certain amino acids. This means that biotin is important for converting the food we eat into energy, ensuring that the body can utilize nutrients effectively.

Understanding biotin's role can help highlight the importance of maintaining adequate intake of this vitamin to support metabolic health. Other options, while related to overall health, do not accurately reflect biotin's primary functions within the metabolic processes of the body.
