Macronutrients Report
Macronutrients should be consumed in large amounts to sustain a healthy lifestyle. Macronutrients consist of the following: carbohydrates, lipids, and protein. In Chapters 4, 5, and 6 the macronutrients affect our energy in metabolism and help maintain our cells and tissues healthy. The first macronutrient I learned about was carbohydrates. Carbohydrates are made up of carbon, hydrogen, and oxygen. Carbohydrates are come from plants and provide our bodies with good energy. Carbohydrates are the preferred energy source by the brain. The digestive process begins at the mouth. Chewing stimulates secretion of saliva from slavery glands. The food is mechanically broken down. An enzyme named salivary amylase breaks starch into chunks of glucose called dextrins and maltose(disaccharide maltose). Once the food reaches the stomach, the acid in the stomach inactivates all salivary amylase. Carbohydrate digestion is not conducted the stomach for this reason. Before the food approaches the small intestine, the pancreas secretes pancreatic amylase. The pancreatic amylase digests starch into maltose. The enzymes maltase, sucrose, and lactase mucosal cells located at the lining of the intestinal track, break disaccharides into monosaccharides. Maltose is broken down into glucose by the enzyme maltase. The enzyme sucrase breaks down sucrose into glucose and fructose. Lactose is broken into glucose and galactose by lactase. Monosaccarides are absorbed into the intestine lining. They enter the bloodstream on their way to the liver. Along the way to the liver, some monosaccarides are picked up by cells and used for energy. Monosaccarides travel to the liver via portal vein. Monosacharides (like Fructose and galactose) are converted to glucose by the liver. After, they are ready to travel to the cells to provide us with energy. Some glucose will stay behind with the liver and become glycogen. Also a small some of glycogen are stored by glial cells
