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 receive the process of emulsification and to canvas the actions of pepsin and saliva (Amylase). Background Information: The decease of the human digestive corpse is to digest solid food that is taken in. Digestion is the process by which large, full phase of the moon-blooded substances such as fats and proteins argon confused put through into underage fat-soluble substances. Digestion consists of two master(prenominal) processes, physical 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. natural digestion takes place mainly in the mouth and potbelly, where it is chewed, grinded, and mixed. Chemical digestion breaks down large molecular substances into simpler substances, changing their chemical properties and structure, exploitation digestive enzymes. Chemical digestion occurs mainly in the stomach and beautiful catgut.          tongue containing amylase acts on amylum to break it down into maltose, in the mouth, scratch line the process by which starch is broken down. After it has been swallowed, the food passes down the oesophagus into the stomach.         The stomach consists of gastric glands that produce gastric juice, which contains pepsin, an enzyme that dissolves proteins into simpler substances called polypeptides. After spending three or four hours in the stomach, the food travels to the itsy-bitsy intestine.

The small intestine is where digestion is completed and its soluble products are absorbed. !         The small intestine receives fluid called gall from the liver. rancour consists mainly of bile salts and atomic number 11 enthalpy carbonate. The bile is slowly secreted into the first 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 made water soluble, using bile salts.         Bile salts are types of...
