Sugars Starches may be named monosaccharides‚ disaccharides‚ or polysaccharides relying upon the quantity of monomer (sugar) units they contain. They constitute a substantial piece of nourishments‚ for example‚ rice‚ noodles‚ bread‚ and other grain-based items. Monosaccharides‚ disaccharides‚ and polysaccharides contain one‚ two‚ and three or more sugar units‚ separately. Polysaccharides are frequently alluded to as

hydrolysed using dilute hydrochloric acid. After hydrolysis and neutralization of the acid‚ the product may be a reducing sugar that gives normal reactions with the test solutions (Benedict’s solution /Fehling solution). Sucrose is the most common disaccharide non-reducing sugar. TEST FOR REDUCING SUGAR Procedure 1. A liquid food sample does not need prior preparation except dilution if viscous or concentrated. For a solid sample prepare a test solution by crushing the food and adding a moderate

In biology‚ there are four major biological macromolecules that are found in the cell‚ carbohydrates‚ lipids‚ nucleic acid‚ and proteins. Biological macromolecules are also known as organic molecules. Biological macromolecules are very large molecules that are of a key importance to living organisms. Most biological macromolecules are built by joining smaller molecule subunits. Carbohydrates are large groups of organic compounds found in foods such as sugars‚ starches‚ glucose‚ fructose‚ galactose

catalyse the reaction of maltose to 2 glucose or lactose to galactose. In this experiment‚ titrimetric and spectrophotometric methods were used to determine the specificity of invertase by determining the amount of glucose converted from the given disaccharides. The results show that sucrose yielded the least amount of glucose and got the lowest absorbance reading. INTRODUCTION Enzymes are globular proteins. Their folded conformation creates an area known as the active site. The nature and arrangement

Problem Set 1 1. Explain lipoprotein physiology and metabolism (Chapter 15). - Lipoproteins are a biochemical formation that aid with the transporting of lipids. The four major pathways include Lipid absorption pathway‚ exogenous pathway‚ endogenous pathway and reverse cholesterol transport pathway. All of these pathways are dependent on a particular particle know as apo-B that contains lipoproteins which‚ functions as a transport for dietary and Hepatic lipids to the outer layers of the cells

the number of repeating units are also much greater than giving the structure variation. Carbohydrates can be broken down into monosaccharides which is a single sugar unit that can be glucose‚ fructose and galactose. This is called catabolism. Disaccharides are 2 sugar units linked together such as condensation‚ lactose‚ sucrose or maltose. Condensation allows to from water. Polysaccharides are multi-sugars. This can provide starch by glyosidic bonds. Another is glycogen. This product is stored as
