to make a longer chain called a polymer. Carbohydrates are categorised in to three main groups; monosaccharides‚ disaccharides and polysaccharides. Monosaccharides are single sugars and are sweet tasting soluble substances such as glucose and fructose which are the building blocks for all carbohydrates. They are used as energy in respiration by being broken down in to carbon dioxide and water. ATP‚ an immediate energy source‚ is released during the glycolysis and the Krebs cycle whilst also being

During stage one raw materials must be 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

It acts as a catalyst for the hydrolysis of sucrose. Sucrose is a disaccharide composed of glucose and fructose linked by a glycosidic bond. When this bond is cleaved in a hydrolysis reaction‚ an equal amount of glucose and fructose. Invertase is a significant enzyme because glucose is an important product of photosynthesis. Invertase is also used in the confectionery industry where fructose is preferred over sucrose because it is sweeter and does not crystallize easily. Enzymes are affected

the taste of a fruit depends on the compounds present in it. Normally a fruit contains the materials like cellulose‚ proteins‚ starch‚ vitamins‚ certain acids‚ fructose or sugar. All these materials are found in mixed form inside the fruit and they have different proportions in different fruits. Fruits of sweet taste have more fructose in them whereas the fruits of sour taste have more acids in them.” (Gemini Geek) so this means that the more or less acid a fruit has then more sweeter or more sour

no nutrition. There are also many health risks when sugar is over consumed. Humans need carbohydrates to survive but there are many healthier way to get them than too many cookies or soda. Simple sugar is made of two components. They are mainly fructose and glucose(Dubost‚ June 12‚ 2013). Sugar is naturally produced in plants during photosynthesis. It is found naturally in milk‚ fruit‚ and vegetables. Sugar can be taken from plants and processed into manufactured products (Perry‚ October 28‚ 2016)

In this lab activity students performed an experiment with the use of distilled water and baking soda solutions as control. The experimental controls are accuracy indicators of laboratory results. Thus‚ controls are important in a lab because the observation results are dependent on the controls. The experimental results can be determined to be valid when it is compared with the control solution. The higher the similarity between the results and the control solution‚ the more accurate the investigation
