What is the meaning of this statement a protein undergoes progressive fragmentation during digestion?

The statement "a protein undergoes progressive fragmentation during digestion" means that proteins are broken down into smaller peptides and amino acids through a series of enzymatic reactions. This process begins in the stomach with enzymes like pepsin and continues in the small intestine with pancreatic enzymes. As the protein is fragmented into smaller pieces, it becomes easier for the body to absorb the essential building blocks, amino acids, necessary for various physiological functions.
