Enzymes Of GIT Flashcards
Pepsin
Digestion of proteins
Salivary amylase
Primary Carbohydrate digestion
Lingual lipase
Primary Lipid digestion
R protein
Binds to vitamin B12 to prevent it from digestion until it gets to stomach
Intrinsic factor
Chief and parietal cells
After r protein, it protects vitamin B12 from digestion in stomach
Brush border enzymes.
On surface of micro villi in small intestine
Disaccharidases - break down carbs
Enteropeptidases - activates trypsinogen to trypsin
Aminopeptidases - catalyze breakdown of peptide
Trypsinogen
Precursor to trypsin
Trypsin
Protein digestion
Pancreatic enzymes
Eg. Pancreatic alpha-amylase(carbohydrase, break downs starches) pancreatic lipase, nucleases, proteases
Continue carbohydrate, lipid and protein digestion as well as nucleic acid digestion
Pepsinogen
Chief cells
Precursor to pepsin
