Answers:Acidity. Typically lactase enzyme works in the duodenum of the small intestine which is actually somewhat basic if im not mistaken. Makers would have to ensure that the enzyme wouldn't denature and lose function in the acidity of the stomach.
Answers:It's actually a type of sugar in milk and dairy products that is called lactose. When you are lactose intolerant, your body does not have enough of the enzyme lactase that breaks down lactose. Usually, you get cramps, nausea and diarrhea. You still get the vitamins and minerals as they are absorbed while in the intestinal tract, but if you have diarrhea you will not absorb enough as things are moving too fast. Head to the drug store and get some chewable tablets that you take before having dairy products. Ask the pharmacist to explain how to use it. There are tablets that have the lactase enzyme in them and they let your body break down that pesky lactose that causes your problems. Al http://phoenixbodystyling.blogspot.com/
Answers:Lactose intolerant people lack the enzyme lactase in their bowel. This enzyme is necessary to digest the lactose. Lactic acid is produced in teh muscles and thus is never exposed to the enzyme lactase in the bowel. THey are 2 mutually exclusive events.
Answers:Digestive enzymes break down macromolecules In the mouth carbohydrate digestion starts. Salivary amylase (in spit) breaks down carbohydrates to simpler sugars (disaccharides and trisaccharides). The stomach initiates protein digestion. Pepsin (an enzyme) breaks down proteins to smaller polypeptides. HCl in the stomach disrupts cell membranes in food. Small intestine is where carbohydrate digestion is completed. Pancreatic amylase (from pancreas) finishes breaking down carbohydrates to simpler sugars (disaccharides and trisaccharides), while maltase (from small intestine) breaks down maltose (a disaccharide) to two glucose molecules. Sucrase (also from small intestine) breaks down sucrose to glucose and fructose and Lactase breaks down lactose to glucose and galactose. Protein digestion also occurs in the small intestine. Enzymes from the pancreas (chymotrypsin, trypsin, carboxypeptidase, elastase) break down proteins and polypeptides to short chain peptides, while pancreatic peptidase breaks down dipeptides and tripeptides to amino acids. Fat is also digested in the small intestine when bile (from the liver) emulsifies fats and lipase(from the pancreas) break down triglycerides to fatty acids and monoglycerides
