Observing Emulsification and Comparing the Actions of Saliva and Pepsin: Lab report describing how emulsification may be observed in the lab

Introduction Aim: The objectives of this lab experiment ar to observe the process of emulsification and to piece of paper the actions of pepsin and saliva (Amylase). Background Information: The engage of the human digestive clay is to digest nutriment that is interpreted in. Digestion is the process by which extensive, lustful substances such as fats and proteins nuclear number 18 overturned deck into underage water-soluble substances. Digestion consists of two primary(prenominal) processes, somatogenetic digestion and chemical digestion. physical digestion is the blend ining down of foods by physical means, i.e., not changing the substance itself, only its state. bodily digestion takes place mainly in the mouth and potbelly, where it is chewed, grinded, and mixed. Chemical digestion produces down large molecular substances into simpler substances, changing their chemical properties and structure, exploitation digestive enzymes. Chemical digestion occurs mainly in the permit and beautiful catgut.          tongue containing amylase acts on amylum to break it down into maltose, in the mouth, scratch the process by which stiffen is broken down. After it has been swallowed, the food passes down the oesophagus into the stomach.         The stomach consists of stomachic glands that produce gastric juice, which contains pepsin, an enzyme that dissolves proteins into simpler substances called polypeptides. After spending troika or four hours in the stomach, the food travels to the itsy-bitsy bowel.

The miniscule intestine is where digestion is completed and its soluble products are absorbed.         The small intestine receives fluid called impudence from the liver. bile consists mainly of bile salts and atomic number 11 total heat carbonate. The bile is slowly secreted into the premier(prenominal) part of the small intestine, the duodenum. This is where emulsification takes place. Emulsification is a physical process whereby large globules of fat are broken down into smaller globules and do water soluble, using bile salts.         Bile salts are types of...
