Digestion Research Paper

Digestion is a form of catabolism process of breaking down food physically and chemically large food molecules in to smaller components. Chemically digestion is carried out using enzymes and hormones with in different segments of the digestive tract. The presence of enzymes in the digestive tract helps breakdown polymeric biomolecules into individual monomers. This process is crucial for surviving because cells cannot use nutrients the way they were consumed without being metabolized. Nutrients need to be small enough to be absorbed by epithelium of the small intestine and transported by the help of carrier proteins. The three primary parts of the digestive tract that carried out digestion directly are mouth, stomach and small intestine.

The

Lipids are the building block of the structures of cells (Ananya Mandal MD, 2012). The digestive organ found following the stomach is called small intestine, it have three parts, duodenum, jejunum, and ilium. Chyme which is a thick liquid mixture of food that come from stomach is digested here with the help of enzymes, once that is complete it is absorbed by the villi of the small intestinal to be delivered to cell. Even though digestion of carbohydrates and proteins already started in the previous organs, digestion of lipids chemically start once they get in to small intestine. The fat in human diet triacylglycerol (three fatty acids and glycerol) gets emulsified by the aid of bile which is secreted by the liver, it is consistent of bile salt and phospholipids in to small droplets. This helps lipase an enzyme from pancreas hydrolyzed triglycerol in to free fatty acids and monoglycerides. The purpose of this experiment is to synthesize digestion of carbohydrates, lipids and peptides using enzymes that catabolize them in order to further understand all the components that goes need to be meet for digdestion to happen by manipulating different variables like pH, and
