Disaccharide

Macromolecules Everything on Earth is made of carbon. Due to this complex molecules are formed. These complex molecules are macromolecules. Macromolecules are polymers, formed by dehydration synthesis. Dehydration Synthesis is when monomers are combines and water is removed. There are four types of macromolecules, carbohydrates, lipids, nucleic acids, and proteins. Carbohydrates are made up of carbon, hydrogen, and oxygen. With a structural components such as glucose and sugar. Carbohydrates can be singular molecules such as monosaccharides, or multiple molecules such as disaccharides. Monosaccharides are glucose and fructose, while disaccharides are sucrose and lactose. These function to store energy in the body. Macromolecules…

A monosaccharide is a one-ringed sugar (part of the carbohydrate category) that is not bonded to any other molecules. A monosaccharide is a monomer of a disaccharide. A disaccharide is two monosaccharides bonded together. The prefixes “mono-“ and “di-“ indicate the amount of rings in the sugar. In this experiment, disaccharides were tested using an enzyme as part of a chemical reaction. A chemical reaction changes substances into different substances by breaking and forming chemical bonds. In a…

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…

The structure and function of carbohydrates (25 Marks) Carbohydrates are made from Carbon (C), Hydrogen (H) and Oxygen (O). A monosaccharide is the monomer sub unit of carbohydrates and can be joined together through a condensation reaction to form a glycosidic bond between the two monomers which is known as a disaccharide. The above diagram shows a condensation reaction taking place. There is a reaction between two monomer sub units, in this case α-glucose and ethanol, which involves the…

This was expected as the compounds were monosaccharides (“Types of Sugar : Monosaccharides and Disaccharides”). Monosaccharides are reducing sugars because they either have a free aldehyde or ketone group. Most disaccharides are typically reducing sugars, though there are exceptions, like sucrose. This was seen in the lab as there was no color change, indicating sucrose was not a reducing sugar. This was as well expected since sucrose does not have a free carbonyl group and cannot convert to the…

It is found in dairy products and is also known as a milk sugar. Its main role in the body is to provide energy. Once it is digested and has entered your cells, it is metabolized for energy. Another positive role of lactose is its ability to allow you to build muscle. A disproportionate amount of lactose in the diet can lead to weight gain and ultimately obesity. This would then increase the risk for cancer, cardiovascular disorders and type 2 diabetes, so it is wise to limit your intake of…

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 are widely known for being the “Building Blocks of Carbs”. An example of a monosaccharide would be fructose; it is a sugar commonly found in…

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…

The purpose of the Benedict’s test was to identify if the food samples and unknowns contained simple sugars. In the sugar, is a ketone or an aldehyde which will reduce copper (II) ions to copper (I) ions (Areda, 2017). This must be done by heating the food sample and Benedict’s solution. The copper will be oxidized resulting in a brown-orange color (Areda, 2017). Thus, if a sample is positive for simple sugars the color will change from a light blue to colors of green, yellow, orange, brown or…

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…
