Document Summary

Break lipid(triglyceride) down into fatty acids and glycerol with the aid from bile. Break down carbohydrates into disaccharides(maltose, sucrose, and lactose) Break down disaccharides into monosaccharides (glucose, fructose, and galactose) Breaks down the starch(carbohydrate) into smaller size sugar molecules. Speed up break down process if more surface area the enzyme have to interact with food molecules. Mixed with bolus, and transform them into chyme. Breaks down protein into smaller peptides once activated with the release of hydrochloric acid. Stomach smaller peptide chains into even smaller segments. Break down the smaller peptide chains into even smaller segments. Activate pepsinogen into its active enzyme form, pepsin. Complete the breakdown of carbohydrate into amino acids. Act as buffer to maintain level of acidity. --------xxxx means important terms that appeared on the sides. Bile is not an enzyme, yet it has important functions. Increase solubility of fat and increase surface areas of fat droplet for better digestion.
