Other dietary sugars such as sucrose and lactose (both disaccharides) are broken down further by different carbohydrase enzymes. NOTE: Ita€™s important you recall the main digestive enzymes, the food types they break down and where they are produced. TOK: This is an example of a paradigm shift, where existing ideas about the tolerance of bacteria to stomach acid were incorrect but persisted for a time despite the evidence. Aim 7: Data logging with pH sensors and lipase, and data logging with colorimeters and amylase can be used.

After being swallowed, the food travels down the Oesophagus or esophagus, this is continually being damaged by the friction of food, so the epithelium is a few cells thick and secretes mucas to lubricate the food's passage. The next place it enters is the stomach this is a temporary store, mixes the contents up and also is the site for a bit of digestion. Enzymes are sensitive to temperature and pH, these must be at an optimum level so they work best.
Below is a digram of the human gut wall, on the right are labelled the different layers that exist. The first actual layer is the mucosa, it has a layer of epithelium, made of epithelial cells, which have projections called villi.
Below this is a muscle layer, known scientifically as the muscularis externa, it is reponsible for peristalsis which moves food through the digestive tract. In the diagram you should also notice the capillaries, part of the blood network which takes absorbed food away. By the time everything reaches here, the food has been digested into small enough particles that it can pass through the alimentary tract lining and be absorbed into the blood.
The food products pass into the blood stream through villi: these are small foldings of the small intestine that cover on its internal surface.
The villi on their own increase the surface area, but the cells which make up the surface of the villus have their own small projections called microvilli (see diagram) these further increase the surface area which means that the digestion products can be absorbed more quickly.
The villus has a supply of blood vessels this means substances absorbed can be transported to where they are needed more directly. Triglycerides are a type of lipid; here you will learn how the body breaks down this molecule. Digestion begins in the duodenum where bile enters from the liver, bile salts make the big blobs of fat into small micelle droplets which massively increases the surface area and makes digestion much easier.


Also in the duodenum, pancreatic lipase this breaks the triglyceride into fatty acid and glycerol. These resynthesised lipids make proteins called chylomicrons, these enter the lacteals and travel through the lymphatic system, making it milky. Cysteine proteases are enzymes found in some fruits as well as in other plants and animal products.
Protein-digesting enzymes, also called proteases or peptidases, are proteins that metabolize other proteins into smaller molecules. Protein digestion occurs through hydrolysis of the peptide bonds that join a protein's amino acids together. The major protein-digesting enzymes in the digestive system are pepsin, trypsin, and chymotrypsin.
Pepsin is the most important of this group, and it is part of an enzyme group called aspartate proteases.
Another of the types of protein-digesting enzymes are called exopeptidases and are manufactured in the pancreas. Another group of protein-digesting enzymes controls the circulation of proteins by degrading excess or damaged molecules. Going off of this article, it has me wondering, are there any diseases out there where people have trouble digesting the enzymes of certain proteins?

Proteins are long chains of amino acids, and protease enzymes break them into peptides (smaller chains of amino acids molecules) and eventually into individual amino acids, which are small and easily absorbed in the small intestine.
It digests complex fat (or lipid) molecules into simple, soluble fatty acid and glycerol molecules.
The story of how the Australians Robin Warren and Barry Marshall made the discovery and struggled to convince the scientific and medical community is well worth telling. Some proteases are a crucial component of the digestive systems of most animals, where they catalyze the breaking down of protein from foods into the amino acids from which these are made.
Many of these enzymes are known as cysteine proteases, and they occur in many animals and plants.

Others serve as catalysts of many basic cell functions, including hormone activation and deactivation, cell death, growth and immune system activation.
Protein metabolism involves dividing proteins into their constituent amino acids, which are then processed by different anabolic pathways into either new proteins or other compounds. These enzumes break down proteins in the stomach and small intestine while other digestive enzymes metabolize carbohydrates and lipids. This group catalyzes some of the chemical cascades that lead immune cells to attack antigens and cause the reactions necessary for blood clotting. This type of enzyme can completely digest a protein because it starts breaking the bonds between the individual amino acids at one end of the chain and continues doing this all the way down to the other end.
They are found in fruits such as pineapple and papaya and account for some of the intense acidity in the juices of these fruits. Not only is this article a great read for those who want to learn about protein digesting enzymes and the like, but it further reinforces what I've learned years ago. However, taking a supplement helps to create these enzymes, thus temporarily allowing them to digest it. Just food for thought.
Bile molecules have a hydrophilic end and a hydrophobic end, and thus prevent lipid droplets coalescing. Different types of proteases are classified according to their mechanism of protein breakdown. Exopeptidases catalyze very rapid digestion of proteins and can be damaging to the surrounding tissue if they leak out of the pancreas and into the bloodstream because of injury. Cysteine proteases are essential to the process of programmed cell death, hormone manufacture, bone development and many signaling cascades in humans. Researchers also believe that this type of protease influences key points in the cell cycle, affecting the different stages of cell growth and division. The need for lipase to be water-soluble and to have an active site to which a hydrophobic substrate binds should be mentioned.
