Contrary to the common misconception that a single protein digests milk, it is a team effort involving several enzymes. This complex process is distinct for the sugar and proteins in milk, with different enzymes acting at various stages of the digestive tract.

The human stomach produces approximately 1.2 to 1.5 liters of gastric juice every day to aid in digestion. This powerful secretion is a complex mixture, which leads many to wonder: is water a gastric juice? The simple answer is no, because water is only one crucial component of this potent, acid-heavy digestive fluid.

Over 90% of ingested protein is broken down into smaller peptides and amino acids in the digestive system. This natural process raises a critical question for supplement users: do peptides break down in the stomach? The answer is a definitive yes, but the story is far more complex and involves a precise, multi-stage enzymatic process.

While mechanical digestion affects all food groups, it's primarily proteins that undergo significant chemical digestion in the stomach. This initial breakdown is crucial for efficient nutrient absorption later in the digestive process. This article details what macromolecules are digested in the stomach and the enzymatic processes involved.
