What is the function of medications like trisodium citrate in the context of digestion?

Trisodium citrate plays a significant role in digestion by acting as a buffering agent. Specifically, it helps neutralize gastric acid, which is important for creating a more favorable pH in the digestive tract. This action can protect the lining of the digestive system and promote better digestive processes. When gastric acid is neutralized, it allows enzymes to function optimally, supporting digestion and nutrient absorption.

While the other options pertain to various aspects of digestion, they do not accurately describe the primary function of trisodium citrate. It does not specifically enhance protein absorption, promote bile production, or directly aid in the metabolism of fats. Instead, its main role is to ensure a balanced pH level in the stomach and intestines, indirectly facilitating the overall digestive process.
