Document Summary

Salivary amylase acts in the mouth, takes complex carbs and breaks down into maltose. Takes starch and breaks it down to maltose. Carbs have been digested only in monosaccharide form have to get out of lumen into blood. Need protein carriers (na+/ glucose symporter) to do this. Glucose or galactose moves with sodium na+/glucose or galactose symporter. Fructose is moved from lumen to cell by uniporter. Amino acids made up of a lot strung together. Pepsin originally pepsinogen, becomes active pepsin when activated by hcl. Majority digested here many enzymes in small intestine from pancrease. Brush border enzymes: part of small intestine wall, aminopeptidase, dipeptidase. All absorption of protein occurs in small intestine. Na+ stays low in cells so we have na+/k atpase. Na+/amino acid symporter takes amino acid into cell on luminal membrane. Not all triglycerides are equal because we have different fatty acids. Fatty acids= 4-24 carbons long (18 is most common)
