AN INVESTIGATION TO FIND THE EFFECT OF BILE SALTS OF ON THE DIGESTION OF LIPIDS I have investigated that if there is an effect of bile salts on the digestion of lipids in the milk. When lipids are broken down in to fatty acids and glycerol (see below)‚ the acid lowers the pH of the mixture. To help me determine and measure the digestion of lipids‚ a pH indicator phenolphthalein has been used to measure the pH of the mixtures. The pH indicator will change the colour from pink to either white (if

Human Digestion Christine Wilkes SCI 241 Natalia Woehl March 8‚ 2011 The human digestion system consists of a series of organs and glads that process the food that we eat. The digestion process starts when food enters the mouth‚ then with the chewing of food. The salivary glads help break down the food with enzymes so that it is easier to swallow. While the food is being chewed it is turned into bolos‚ which then travels down the pharynx and through the esophagus. The esophagus is the long

APPLICATION OF CHEMICAL SENSORS IN MECHANICAL ENGINEERING A chemical sensor is a device that transforms chemical information‚ ranging from the concentration of a specific sample component to total composition analysis‚ into an analytically useful signal. The chemical information‚ mentioned above‚ may originate from a chemical reaction of the analyte or from a physical property of the system investigated. Chemical sensors its application in various fields of engineering like civil‚ environment‚ medical

bio gas Co-digestion of Biomass for Methane Production: Recent Research Achievements Wei Wu ABSTRACT Anaerobic digestion (AD) is a process by which microorganisms break down biodegradable material in the absence of oxygen. Anaerobic digestion can be used to treat various organic wastes and recover bio-energy in the form of biogas‚ which consists mainly of CH4 and CO2. A great option for improving yields of anaerobic digestion of solid wastes is the co-digestion of multiple substrates. Numerous

Bio 6 (Mon. Lab) 5/6/13 The Effects of Pepsin VS. Trypsin in The Digestion of Protein Introduction As food is mechanically and chemically digested through our oral cavity then passes through our pharynx and down our esophagus‚ our food then enters the stomach. The stomach‚ being the main organ for storage‚ also helps with breaking down our food‚ but in order to accomplish that our pancreas helps by excreting an inactive digestive enzyme called pepsinogen. Pepsinogen is the inactive form

Digestive system 6.1.1 explain why digestion of large food molecules is essential * Large food molecules are polymers‚ broken down into monomers in order to be absorbed into the blood * Humans eat substances by other organsims‚ many which are not suitable for human tissues therefore they must be broken down and reassembled in a form that is suitable * Many molecules in foods are too large to be absorbed by the villi in the small intestine‚ the large molecules have to be broken down
