Science of Human Nutrition Week 7 notes Inside the Female body video http://www.youtube.com/watch?v=Uzl6M1YlU3w&feature=related When food hits the stomach, it sends signals to the brain to churn food once everything is liquefied, moves into the gastrointestinal tract the bile secreted into the small intestine to help break down fat 2 Classifications of nutrients Macronutrients: carbs, fats, proteins polysaccharides- complex carbohydrates or starches- 3 or more molecules Carbohydrates monosaccharides (simple sugars)- 1 molecule simplest form of carbs goal of digestion is to break apart carbs until left with glucose, fructose and galactose Galactose- found mainly in dairy products fructose- found in fruits and vegetables the absorbable units of carbs Disaccharides- only 3 sucrose-table sugar (REMEMBER FOR EXAM) glucose and fructose = sucrose maltose= glucose + glucose lactose = glucose + galactose – found in milk Glucose and fructose have to be a perfect combination (EXAM) People who are lactose intolerant are lacking lactase to break down the molecule (EXAM) Proteins amino acids- 1,2,3 or more Fats start to weaken bonds in the mouth Like an ‘E’ have a glycerol back bone and 3 fatty acids Fatty acids- 3 molecules of fat Glycerol- 1 molecule of fat Micronutrients vitamins and minerals not digested released and activated through the process of digestion Absorbable forms of nutrients Carbohydrates= absorbable units are monosaccharides once they are absorbed in the blood, fructose and galactose will eventually become glucose (only occurs in the blood, main goal) which of the following is the only source of usable energy ? glucose (EXAM) stored in muscle and liver glycogen is the stored form of glucose Proteins- absorbable unit is amino acids Fats- absorbable form fatty acids and glycerol Vitamins and minerals- not broken down Enzymes complex protein substances that speed up reactions that break down food proteins need a protein to break It down Locations of enzymes Fats start to be weakened in the mouth, not broken down Carbs and proteins break down in mouth Disachharides are broken down in small intestine if eating a simple sugar that is 1 or 2 molecules, digestion takes place in small intestine polysaccharides-broken down in stomach HCL breaks down everything Pancreas amylase made in pancreas, make their way in to small intestine pancreatic lipase finishes fat breakdown, fats can be absorbable pancreatic tripsim finalizes protein breakdown (digestion) gastrointestinal tract (GI) sucrose- breaks down sucrose lactase- breaks down lactose maltase-breaks down maltose finalizes carb digestion Bile- break down fats Enzymes and nutrients (proteins) pepsin, trypsin and HCL assists in breakdown Enzymes and nutrients (Fats) Bile- produced in liver, stored in gallbladder, breaks down in small intestine HCL- stomach Lipase, HCL, bile- helps in fat breakdown Human digestive system video http://www.youtube.com/watch?v=b20VRR9C37Q GI- small intestine and large intestine (colon) colon absorbs water and sodium
