Identification of Unknown Carbohydrates using various biochemical tests Date of experiment: 11/10/2012 Name of Student: Vicki Marshall Introduction A series of biochemical tests was carried out to identify unknown carbohydrates. There were six carbohydrates that needed to be identified; they have been randomly labelled A-F. The carbohydrates are glucose‚ fructose‚ maltose‚ lactose‚ sucrose and starch. There was six tests that were carried out to help identify them‚ these were: Iodine Test

Cells are dynamic structures with constant activity The carbohydrates are unique in forming long chain polymer and also branching these chains. This is more complicated than protein where only 20 amino acids can form a long single chain. Here there can be numerous kinds of bonding forming a straight chain or long chain polymer. More over the number of repeating units are also much greater than giving the structure variation. Carbohydrates can be broken down into monosaccharides which is a single

highest rates and that lactose was the lowest‚ so we see a clear downwards sloping trend‚ which was also expected. This suggests that yeast respires best with glucose instead of sucrose fructose or lactose. To explain this process‚ we must first understand how sugar affects yeast growth. First of all yeast is a fungus‚ meaning that it needs sugars to supply it energy. Yeast can also release oxygen like human beings‚ called respiration. So technically speaking the more sugars there are the more

Investigating a factor that affects the rate of enzyme activity Enzymes speed up reactions. They have an area with a very particular shape called the ‘active site’. When the right molecule comes along (substrate molecule) it will fit perfectly into the active site and there will be a reaction. After the reaction the products then leave the active site. This process is often referred to as the lock and key theory as only one enzyme can carry out one type of reaction. The catalase enzyme speeds

which usually results in folding of the protein into a specific three-dimensional structure that determines its activity. What is starch?2 Starch is a carbohydrate consisting of a large number of glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants as an energy store. It is the most common carbohydrate in human diets and is contained in large amounts in such staple foods as potatoes‚ wheat‚ maize (corn)‚ rice‚ and cassava. Its presence or absence in samples

Different Learning Styles for Different People As we learn more from one generation to another on how the brain and body work together the more we change how we teach our children. The curriculum in schools today is far different than what it was 40 years ago and will continue to change as we discover more on how we learn. In recent years there has been extensive research and exploration on helping all students reach their full potential. Throughout history it has been thought by scholars
