Monosaccharide

The purpose of this experiment is to detect the presence of saccharides in different samples through the use of Benedicts reagent and Lugol’s solution. Monosaccharides have a double bonded oxygen atom that forms in one of its two possible chemical groups known as ketone or aldehyde. Disaccharides are two monosaccharides joined together by a glycosidic bond. The Benedicts reagent reacts with the double bonded oxygen atom in monosaccharides by reducing the copper sulfate found in the reagent. Therefore, Benedicts reagent is used in this experiment to detect the presence of monosaccharides and disaccharides. Polysaccharides are chains of linked glucose molecules. The two types of dietary polysaccharides are Amylose and Amylopectin. The Benedicts…

1. What is the difference between a monosaccharide and a disaccharide? Provide examples of each. Ans. Monosaccharide is a monomer that only consists one sugar but disaccharide has two. 2. Why is a sugar considered an organic compound? Ans. Because a compound that contains carbon is organic and the compound that doesn’t contain carbon is inorganic. 3. What are the three elements found in all sugars? Ans. Hydrogen, oxygen and carbon. Lipids 4. What are the two main parts of a lipid? Ans. Fatty…

Practical Report (Determination of blood glucose levels and qualitative carbohydrate tests) Introduction: The term ‘’Carbohydrates’’ is defined as the carbon compounds which contains hydroxyl groups in large quantities (King, 2013). Carbohydrates are those organic compounds that have the empirical formula CnH2nOn, or (CH2O)n (Fromm 1997). Carbohydrates are one of the four types of organic compounds in living cells that are produces during photosynthesis and are the important source of…

To answer the question, it is first necessary to understand what a polysaccharide is and what hydrolysis is. The four "building blocks of life" is a commonly used phrase that refers to four kinds of small molecules that are essential in the creation and formation of larger macromolecules that exist in every living organism. These four molecules consist of simple sugars, fatty acids, amino acids, and nucleotides. "Poly-" means "many", and "saccharide" means "sugar," so as the name suggests, a…

Identifying Unknown #1103 Purpose: There are four naturally occurring organic macromolecules essential to all living organisms. These organic macromolecules which are essential to all life are carbohydrates, proteins, lipids, and nucleic acids.. These four organic macromolecules provide all cells with structure, create and store energy, and can be hormones, immune substances and genetic material. A macromolecule, or polymer, is a large complex molecule built from smaller molecules, or…

Glucose is a monosaccharide which is a simple sugar make up of a single chain or ring of carbon atoms with hydroxyl groups attached. Their carbonyl group is what distinguishes them. It has a sweet taste and is soluble in water. A nitrogen atom is present in amino acids but not in sugar molecules Elements found in lipids are hydrogen, oxygen, and carbon. Purpose The purpose in this lab is to determine the presence of certain macromolecules made by cells by detecting carbohydrates, lipids and…

Carbohydrates are classified into three groups Monosaccharides or Monosachoroses From Greek, mono=one; sakchron=sugar. 1. Monosaccharides Monosaccharides are simple sugars, which possess a free ketone or aldehyde group. Being the simplest of sugars, they cannot be further hydrolyzed. Their chemical formula is CnH2nOn or Cn(H2O) n. Monosaccharides are classified into tiroses, tertroses, pentoses, etc., and as ketoses or aldoses, depending on their ketone or aldehyde group. Examples of…

In lecture, we learned that carbohydrates are compounds that include: sugars, starch, and cellulose; the latter existing in plants. Carbohydrates function as an energy source, provide cell structure, and aid in cell identification. All carbohydrates are made up of Carbon, Hydrogen, and Oxygen, Hydrogen and Oxygen having a two to one ratio. Also, there are three major groups of carbohydrates: monosaccharides, disaccharides, and polysaccharides. Monosaccharides are classified as simple sugars and…

They are monosaccharides, disaccharides, and polysaccharides. Monosaccharides are the simplest units of carbohydrates and a simple carbohydrate. They are the building block of more complex of carbohydrates such as disaccharides and polysaccharides. According to orthomolecular.org, monosaccharides are colorless; they can dissolve in water and have crystal like appearance (orthmolecular.org). Disaccharides are made up of two monosaccharide units linked through glycosidic bond. Polysaccharides are…

Scicurious, High Fructose Corn Syrup: Much Maligned? Or the Devil’s Food Cake?, August 23, 2011, Fructose is a yellowish white crystallized, water soluble ketonic monosaccharide sugar found in many plants, C6H12O6. It is sweeter than sucrose and often bonded to glucose to form the disaccharide sucrose. Triglyceride is a type of fat (lipid) found in the blood. When we eat, our body convert any calories that doesn’t need to use right away into triglycerides. Triglycerides are stored in the fat…
