The word monosaccharide is derived from mono, meaning one, and saccharide , meaning sugar the common monosaccharides are glucose, fructose, and galactose each simple sugar has a cyclic structure and is composed of carbon, hydrogen and oxygen in ratios of 1:2:1 respectively although each sugar mainly. Objective: to characterize carbohydrates present in an unknown solution on the basis of various chemical assays theory: carbohydrates are polyhydroxy aldehydes and ketones or substances that hydrolyze to yield polyhydroxy aldehydes and ketones aldehydes (–cho) and ketones ( = co) constitute the major groups in. The science of nutrition laboratory science 70 simple sugars (simple carbohydrates), such as fructose, glucose, and lactose, found in materials: hot plate, 500 ml beaker, 6 test tubes, water, 6 food products (choose from grain products, milk products, and fruits or vegetables), and benedict's solution method 1. Monosaccharides are single sugars that react with a mixture called benedict's reagent or benedict's solution the reaction changes the color of the reagent to green, red or orange depending oh how much sugar is present benedict's reagent can be used to test for the presence of many of the simple sugars complete the.

Carbohydrates serve as energy sources and provide structural support as in the cell wall of plants carbon, hydrogen, and oxygen are the elements found in carbohydrates exercise 1 - benedict's test for reducing sugars benedict's reagent is used as a simple test for reducing sugars a reducing sugar is a carbohydrate. Three of the most important simple sugars—glucose (also known as dextrose, grape sugar, and corn sugar), fructose (fruit sugar), and galactose—have the same molecular formula, (c6h12o6), but, because their atoms have different structural arrangements, the sugars have different characteristics ie. N camien, max s dunn, and a j salle (from the chemical laboratory and the department of bacteriology, university of california los angeles) ( received for publication, august 14, 1946) it was observed in the two preceding investigations (1, 2) on the amino acid and vitamin requirements of twenty-three strains.

Hour growth from a bap (figure 1) or a cap (figure 2) at 35-37°c with ~5% co2 (or in a candle-jar) the following tests are recommended to confirm the identity of cultures that morphologically appear to be n meningitidis (figure 3) n meningitidis can be identified using kovac's oxidase test and carbohydrate utilization. Simple carbohydrates include familiar sugars such the monosaccharides glucose (the basic fuel of cells) and fructose (found in fruits) common see tube 1 above glucose plus benedict's reagent is a positive control for the sugar test it demonstrates what a strong positive result should look like it also proves that our. The term carbohydrate literally means hydrated (h20) carbon carbohydrates may contain one sugar molecule (monosaccharides), two sugar molecules ( disaccharides), or many sugar units (polysaccharides) in this lab, we will be concerned with the nature and activities of the carbohydrates and with their structure. 1 laboratory 5 carbohydrates, carboxylic acids, aromatic and heterocyclic compounds i characteristic reactions of carbohydrates 1 schiff's reagent test schiff's reagent reacts with two aldehyde groups of aldehydes and 2-deoxycarbohydrates, finally a violet- purple products are formed.
