The Digestion process The digestive process is important in maintaining the lives of living organisms and in providing them with needed energy and nutrition. Groups of organs‚ such as the mouth‚ esophagus‚ stomach‚ intestines‚ pancreas‚ and gal bladder work together to perform this complex task. Digestion is the process of breaking down food from large molecules into small ones to make it easier for absorption. The three major steps involved in the digestive process are ingestion‚ digestion‚ and

six elementary groups: carbohydrates‚ fats‚ proteins‚ vitamins‚ minerals‚ and water. These foods are broken down into various nutrients during digestion. The time taken for the body to extract nutrients and the complexity of the digestion process depend on the molecular nature of the food eaten. Fat molecules seem more complex than the others so its digestion often takes a longer time. Types of Fat Fats molecules are made of carbon‚ hydrogen‚ and oxygen atoms. Based on the arrangements of these atoms

[pic]Theory notes: Digestion is the process of breaking down organic food into molecules that are small enough to enter cells Chemical digestion : the process of breaking apart complex molecules into simple molecules is called chemical digestion when carried out by enzymes. Mechanical digestion: Is the physical breaking down of larger food into pieces to increase its surface area (the higher the surface area‚ the higher the rate of chemical digestion. Peristalsis: the squeezing of the

The digestion of milk fats by pancreatic lipase and the digestion of proteins by pepsin and trypsin By Jenny Lam Abstract The purpose of this project was to determine how pancreatic lipase and bile salts digest fats to fatty acids and glycerol and how pepsin and tryspin digest to polypeptides. Litmus solution (pH indicator) was used for the fats to indicate the occurrence of the digestion of fats in experiment A. Egg whites was used as the substrate for the enzymes in experiment B.
