Disaccharide

down to simpler monomer to start the process of glycolysis, so the fastest rate of fermentation will occur to the simplest substance (glucose). During the experiment, Glucose exhibits the formation of CO¬2¬ after 5 minutes (0.1 mL), while Maltose (disaccharide), required one step of break down sugar, is slower, and gas formation only clearly visible at 10 minutes. On the other hand, starch, is a polymer, which required multiple steps to be broken down, is the slowest substance with 0 mL of…

Carbohydrates : Carbohydrates are commonly identified as sugars, they are the 'staff of life' for mainly organisms. They are mainly rich class of biomolecules in nature, based on mass. Carbohydrates are also known as saccharides, in Greek sakcharon mean sugar or sweetness. They are generally distributed molecules in plant and animal tissues. In plants, and arthropods, carbohydrates from the skeletal structures, they also provide as food reserves in plants and animals. They are main energy…

Biuret Test and many others. With these tests, the nutrients from an unknown solutions can be identified in the solution. The Benedict’s test is used for identifying reducing sugars, which are simple sugars that include monosaccharides and some disaccharides. The Benedict’s reagent is made of Copper (II) sulfate ion which reduces to Copper (I) during the test. It is made by adding copper sulfate with sodium citrate and carbonate that is dissolved in 400mLs of water (Benedict’s Test). The…

Cyclodextrins are enzymatically modified starches composed of glycopynanose units which form a ring of either six (α-cyclodextrin), seven (β-cyclodextrin) or eight (γ-cyclodextrins) units. Characteristics of β-cyclodextrins include: • Glucose unit: 07 • Molecular weight: 1135 • Solubility =1.85g/100ml • Cavity diameter = 6.4 Ǻ • Diameter of outer periphery = 15.4 Ǻ • Approx. volume of cavity = 262 (Ǻ)3 Cyclodextrins have a cylindrical shape with central axial cavity and resembles the shape of a…

“Just a spoonful of sugar helps the medicine go down in a most delightful way, “ sand Mary Poppins. Well, of course it does! What better way to mask the bitter taste of medicine then lace it with sweetness. However, the problem is the average person in the US consumes way more that the 50g of sugar per day recommended by the World Health Organization (WHO). A 2014 study conducted by the WHO concluded that the average US citizen consumes more than 126 grams of sugar per day. A sugar laden diet…

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…

Purpose The main purpose of this experiment to learn about the organic molecule of the substances that we use daily with the common foods. The organic molecule that we use for this lab are monosaccharides of sugar, protein, starch, lipids, nucleic acids, and carbohydrates. Introduction Carbohydrates are the organic compounds that are organized as the ring structures and always compose the carbon, hydrogen, and oxygen atoms that represent by the structure of H2O. The carbohydrates are…

Summary: All biological molecules contain carbon, hydrogen, and oxygen. A carbohydrate (C,H,O) is a biological molecule consisting of hydrogen , carbon, and oxygen atoms exclusively. They are the building blocks for polysaccharides, larger more complex carbohydrates. An example of a carbohydrate is glucose (the energy source for plants). Carbohydrates are the source of short term energy in organisms. Proteins (C,H,O,N) are made of carbon, hydrogen, oxygen, and nitrogen on a base level. Proteins…

FDE 310 Food Materials Laboratory Report Determination of Reducing Sugar Content INTRODUCTION The objectives of this experiment is to determine reducing sugar content of food sample by performing Fehling method and to identify invert sugar content of sugars by using polarimetry and also to learn property of invert and reducing sugar. Carbohydrases represent a large class…
