Chemical digestion & absorption in the stomach
1) Carbohydrate digestion is continued with gastric amylase , resulting in disaccharides.
2) Protein digestion begins with pepsin (activation of pepsinogen by HCl) , resulting in peptides (small chain of protein).
3) Lipid digestion begins with gastric lipases which can only breakdown certain lipids such as butterfat, resulting in fatty acids.
4) Absorption in the stomach is limited, where only small and fat-soluble subtances can be absorbed - water, alcohol, aspirin, and certain drugs.
5) the result of all these mixing, chemical digestion, secretion, and absorption is a yellowish paste called chyme which will be passed on to the small intetsine.
