Final answer:
The AI for Pantothenic acid (Vitamin B5) is the intake level assumed to ensure nutritional adequacy; it is necessary for energy production from foods and participates in various metabolic processes as part of coenzyme-A.
Step-by-step explanation:
The AI (Adequate Intake) for Pantothenic acid, also known as Vitamin B5, is the amount considered sufficient for maintaining healthy bodily function in an average person. Pantothenic acid is a vital nutrient that plays a crucial role in energy production by assisting in the metabolism of foods, particularly lipids. It is part of coenzyme-A, which is essential for the synthesis of fatty acids, cholesterol, and for the operation of the citric acid cycle.
In supplements, the amount of pantothenic acid provided is often 10 mg, which supports the body's needs. This vitamin is abundant in nature and can be found in a wide variety of foods, including honey, which is one of its richest sources. Our intestinal flora also contributes significantly to the supply of this vitamin.
The chemistry of pantothenic acid involves a combination of ß-alanine and pantoic acid joined by a peptide bond. It is important for growth, particularly in infants and children, and for various metabolic processes, including the activation of fatty acids for oxidation and cholesterol synthesis.
