The pantothenic acid portion of coenzyme A is released during digestion in the small intestine.

Explanation:

Coenzyme A (CoA) is essential for various biochemical reactions in the body, particularly in the metabolism of fatty acids and the synthesis of acetyl-CoA. During the digestive process, food that contains CoA undergoes enzymatic breakdown throughout the digestive tract. While digestion begins in the mouth and continues in the stomach, the majority of nutrient absorption, including that of pantothenic acid, occurs in the small intestine.

In the small intestine, enzymes further break down food particles, allowing for the absorption of vitamins, minerals, and other nutrients into the bloodstream. Pantothenic acid, being a water-soluble vitamin, is readily absorbed through the intestinal wall and then utilized by the body's cells for various metabolic processes.

Thus, the role of the small intestine is crucial in releasing and absorbing pantothenic acid from coenzyme A during digestion.
