carbon. Sugar contains sucrose which is the common saccharide in many plant parts. Sucrose (sugar) is composed of 12 carbon atoms‚ 22 hydrogen atoms and 11 oxygen atoms. Therefore‚ the chemical formula of compound sugar C12H22O11. Figure 1‚ shows the structure of sugar as a 3D diagram. Figure 2‚ is a demonstration of the structure of sugar in a 2D diagram. The molar mass of compound sugar is 342.2965g/mole with a density of 1.59g/cm3 and a melting point of about 186

Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

I. Science Fair Question How do digestive enzymes convert sucrose and lactose into glucose? II. Background Research Do you enjoy eating smoothies packed full of berries and other tasty fruits? This paper is going to discuss how digestive enzymes convert sucrose and lactose into glucose. The following terms will discuss; Sucrose‚ Glucose‚ Lactose and Digestive Enzymes. Sugar is any of a class of crystalline carbohydrates such as sucrose‚ glucose‚ or lactose‚ that dissolves in water and have a characteristic

correlation of percent change in weight for each sucrose concentration with AgNO3 added. The initial length of the potato cylinders were 2cm as depicted in table two. Graph two depicts the correlation of percent change in length in different sucrose concentrations. The initial weights for the solutions lacking AgNO3 ranged from 1.0-1.7grams (Table 3). Graph three displays the correlation for the percent change in weight for a solution lacking AgNO3 in different sucrose solutions. The initial lengths of the

converted to sugars through a process that is known as fermentation. Sugars in the form of sucrose are mostly used by humans (Alexander N.Glazer). Sugar cane and sugar beet are composed of 20% sucrose‚ 75% water‚ 5% cellulose and about 1% is inorganic salts (Alexander N.Glazer). Sucrose is extracted with water by using mechanical pressure from the sugarcane. On the other hard the beet is peeled and crushed. Sucrose that was extracted from sugarcane is a highly effective substrate that is used during

Effect of Sucrose Solution on Osmosis Aim: The aim of the experiment is to show how varying the concentration of sucrose solution affects osmosis by changing different molar solutions of sucrose and water and how it affects the potato. Introduction: In this investigation I will be exploring the effect of varying concentration of sucrose sugar solution on the amount of activity between the solution and the potatoes. Osmosis is the movement of water molecules across a partially

report: Topic: Osmosis of potatoes in different sucrose solutions. The aim of this experiment is to test whether more water moves out of a potato when it is placed in a sweeter sucrose solution than a potato in a less sweet solution. The hypothesis of the experiment is that we expect more water to move out of the potato placed in the sweet solution than the potato placed in a less sweet solution. Independent variable: concentration of sucrose‚ concentrations: pure water H20‚ 0.1 M‚ 0.5M‚

Extraction The first stage of processing is the extraction of the cane juice. In many factories the cane is crushed in a series of large roller mills: similar to a mangle [wringer] which was used to squeeze the water out of clean washing a century ago. The sweet juice comes gushing out and the cane fiber is carried away for use in the boilers. In other factories a diffuser is used as is described for beet sugar manufacture. Either way the juice is pretty dirty: the soil from the fields‚ some small

obesity percentages. Sucrose is the leading added sweetener in in the manufacture of foods in the Unites States and is the biggest source of fructose. Sucrose and high fructose corn syrup (HFCS) are metabolized identically and react the same way to insulin‚ leptin and ghrelin. Sucrose is indifferent from HFCS in causing obesity. Compared to glucose‚ sucrose is extracted directly from the liver while glucose goes directly to the bloodstream causing larger sugar spikes. HFCS and sucrose have an identical
