Document Summary
Class: fst 010 topic: di- and complex carbohydrates. Maltose: malt sugar , prepared by yeasts or enzymes acting upon starches, a disaccharide (2 glucose moieties) Lactose: disaccharide from mammalian milks, composed of glucose and galactose, 1/6 sweetness of sucrose, low solubility, milk proteins: casein and whey. Extremely rare genetic condition (exception is premature babies b/c of underproduction of lactase) Not compatible w/ normal life unless there"s medical intervention. Truly lactose-intolerant baby wouldn"t thrive from birth (no weight gain) and show obvious symptoms of malabsorption and dehydration. Baby would need special diet immediately after birth: secondary lactose intolerance. Lactose produced in very tips of microscopic folds of intestine (anything that damages the gut lining can cause secondary lactose intolerance) Even subtle damage to the gut may wipe off the tips and reduce the enzyme production. Cheese: natural aged cheese (cheddar, parmesan, swiss) Trace levels (less than 0. 5 g of lactose)
