Introduction A series of biochemical tests was carried out to identify unknown carbohydrates. There were six carbohydrates that needed to be identified; they have been randomly labelled A-F. The carbohydrates are glucose‚ fructose‚ maltose‚ lactose‚ sucrose and starch. There was six tests that were carried out to help identify them‚ these were: Iodine Test‚ Solubility in Water‚ Benedict’s test‚ Acid Hydrolysis‚ Barfoed test and Diastix test. Aim The aim of the experiment which was carried out was

components of nucleic acids (D-ribose and 2-deoxy-D-ribose). Monosaccharides‚ oligosaccharides‚ and polysaccharides are theclassifications of carbohydrates. This experiment involves the carbohydrates starch‚ glucose‚ fructose‚ maltose‚ xylose‚ and sucrose. These carbohydrates are the standards to be used in determining the unknown sample with the help of the Barfoed’s test‚ Benedict’s test‚ Bial’s Orcinol test‚ Seliwanoff’s test‚ and Iodine test. Introduction Carbohydrates are the single most

Benedict’s solution which is used in the test. This was the test for reducing sugars. If the reducing sugar test comes out as negative (no colour change)‚ the non-reducing sugar test can be done. The non-reducing sugar test works because if there is any sucrose present (which is a non-reducing sugar‚ that we are testing for)‚ it is broken down into those monosaccharides‚ which can be tested for using the ordinary reducing sugar test. A positive result therefore means non-reducing sugars are present on the

1. Provide aim and background information 1.1 Diffusion is the process which molecules dissipate into a solution evenly over a period of time. An example is putting sugar in your coffee‚ after a while if you don ’t mix the solution‚ the sucrose will over time‚ go through the process of diffusion and be distributed throughout the coffee. Osmosis is movement of H2O molecules passing through a permeable cell membrane to the less concentrated solution‚ eventually to reach an equivalent number of molecules

dietary monosaccharides‚ along with fructose and galactose‚ that are absorbed directly into the bloodstream during digestion. Sorbose - it is a ketose belonging to the group of sugars known as monosaccharides. It has a sweetness that is equivalent to sucrose. The commercial production of vitamin C often begins with sorbose. Maltose – it is a disaccharide formed from two units of glucose joined with an α bond‚ formed from a condensation reaction. The isomer isomaltose has two glucose molecules linked

involving the appearance of NADPH. Sucrose and glucose concentrations were calculated from the concentration of NADPH formed by the reaction of glucose-6-phosphate and NADP+. Spectrophotometric absorbance readings were taken at 340nm‚ this is because NADPH absorbs strongly at this wavelength‚ whilst NADP+ does not (1015MSC‚ 2010). The concentration of glucose and sucrose in Powerade was found to be 0.43g/100mL and 7.36g/100mL‚ whereas the concentration of glucose and sucrose in Gatorade was found to be

galactose (both six-sided sugars). Sucrose‚ ordinary table sugar‚ is also a disaccharide composed of fructose and glucose. Glucose is a six-sided sugar and fructose is a five-sided sugar. Lactase is an enzyme that breaks lactose down into galactose and glucose. Lactase can be purchased in pill form by people who are lactose intolerant. These people lack the enzyme‚ lactase‚ and cannot break down the sugar lactose into its component parts. Although lactose is similar to sucrose‚ lactase will break down only

caramel colors‚ solubility and acidities are directed by some catalysts to increase the reaction. Mostly some of the unsaturated rings condense into polymers yielding the different colors. One of the commonly used sugars during caramelization is sucrose solution. The brown caramel color produced in its reaction with ammonium bisulfate is used in cola soft drinks‚ syrups‚ candies‚ pet foods and dry seasonings. Solutions of it are acidic with pH ranges from 2-4.5 and with colloidal particles having

This is the portion of the sugarcane juice which contains sugars other than sucrose (what is normally consumed) and a number of other organic compounds. One of the compounds formed during fermentation of molasses is ethanol. In addition to sugar‚ about 12 million litres of ethanol are produced annually at the two factories in Sevanagala
