Pepsin

lack rennin, milk is coagulated by the action of pepsin, as is the case in humans. A commercial form of rennin, rennet, is used in manufacturing cheese and preparing junket. (Encyclopaedia Britannica, 2015) Rennin is absent in…

The first enzyme to be inactivated by ultrasonic waves was pepsin about 60 years ago and the mechanism of inactivation was cavitations (Geckeler, 2009). Heat was the common method used in inactivation of enzymes, however, was observed to lower the quality of the preserved food as well as destroying food nutrients. Ultrasound is being tested as an alternative in enzymatic inactivation (Geckeler, 2009). Since 60 years ago ultrasound has been observed to be an efficient method in enzyme…

The enzymes in the stomach break down food as well as kill bacteria. What cells in the stomach function to form enzymes and acids? Parietal cells in the stomach create hydrochloric acid and pepsin which digests proteins. Why doesn’t gastric juice digest the inside of the stomach? The stomach mucosa that lines the stomach is able to resist the juices of the stomach acid. What are sphincters and how are they related to the stomach? The first is the cardiac sphincter located at the top of…

• Peristalsis – rhythmic muscular contractions of the digestive track that move its contents along the digestive track. • Segmentation – contraction happening in the small intestine. It divide and mixes the chime (partially digested food and digestive juices) • Enzymes – proteins that speed up chemical reactions without change to themselves. • Esophageal sphincter – the opening between the esophagus and he stomach that relaxes and opens to allow the bolus to travel into stomach and then closes…

of eating because of the relaxation of the LES. There are a few factor contributing to the development of esophageal reflux. The contents of the stomach can determine the degree of severity. For example, “If the chime is highly acidic, or contains pepsin, bile salts and pancreatic enzymes, reflux esophagitis can be severe” (McCance, 2010,p. 1458). Increased abdominal pressure due to obesity or physical activity can also contribute to the disorder. A patient with GERD would present clinically…

stomach. The stomach secretes gastric juice which the stomach utilizes to prevent bacterial growth and kills bacteria in the food that enters the body. There is then the major digestive of breakdown of proteins which occurs during the stomach digestion. Pepsin is an enzyme found in the stomach and is used to degrade proteins from food into peptides.…

Normal pathophysiology of gastric acid stimulation and production. Normally the stomach holds around 50cc of fluid. There are several stimuli that work together in the complex process of the digestion process (Huether & McCance, 2012). There are three phases of gastric secretion, first being the cephalic phase, which is stimulated by the thoughts , smells and taste of food. Stimulation releases acetylcholine and the release of gastrin-releasing peptide, thus indirectly stimulates hydrogen ions.…

Helicobacter pylori are spiral and rod-shaped Gram-negative bacteria [1] that colonize the gastric mucosa of about half of the world’s population [2]. This bacterium has been associated with several gastric diseases such as chronic gastritis, peptic ulcer and gastric cancer [3]. Contamination is usually acquired in childhood [4,5], probably by ingesting food or water contaminated with fecal matter [6,7], and, once established, H. pylori has no significant bacterial competitors [8]. In order to…

classic vanilla to the iciness mint flavor.There are many types of gums available in the market,from gum used to color our teeth and even the gums used for medical purposes.Today,different type of gums are made from different kind of ingredients like pepsin,guarantee and even nicotine.But overall,chewing gum gives us a relief feeling and people enjoy chewing gum. Chewing sugarless chewing gum has been shown to rapidly increase the flow of saliva which thereby plaque acid,strengthens teeth and…

The regulation of acid and pepsin secretion is associated with a balance of chemo-transmitters delivered to the gastric mucosa by pathways that facilitate stimulation and inhibition. The physiologic stimulation of acid secretion is divided into the cephalic, gastric, and intestinal. The main component of gastric secretion is HCL which is a product of the parietal cells. The parietal cells are epithelial cells that secrete HCL and essential factors. Parietal cells are located in the gastric…
