Exam question.
-
Proteins are broken down to dipeptides and tripeptides, and later those are broken down to amino acids. Carbohydrates are broken down to monosaccharides (glucose, fructose, galactose) and disaccharides (maltose, sucrose, lactose). Lipids are broken down to glycerol and free fatty acids. Hope this helps.

Digestive enzymes are classified based on their target substrates:
proteases and peptidases split proteins into their monomers, the amino acids.
lipases split fat into three fatty acids and a glycerol molecule.
carbohydrases split carbohydrates such as starch and sugars into simple sugars such as glucose, the simplest sugar on earth.
nucleases split nucleic acids into nucleotides.
In the human digestive system, the main sites of digestion are the oral cavity, the stomach, and the small intestine. Digestive enzymes are secreted by different exocrine glands including:
Salivary glands
Secretory cells in the stomach.
Secretory cells in the pancreas.
Secretory glands in the small intestine.
