Structure and function of macromolecules within a living organism ‘Some biological molecules in organisms are small and simple containing only one or a few functional groups‚ others are large‚ complex assemblies called macromolecules’ [1]. The term macromolecule is convenient because the bulk properties of a macromolecule differ from those of smaller molecules. These large chemical compounds have a high molecular weight consisting of a number of structural units linked together by covalent

two layers. This is because the samples used in this experiment are maltose‚ glucose and starch which are considered as carbohydrate that should give a positive reaction. Monosaccharides give a rapid positive test compare to disaccharides and polysaccharides which will react slower. Therefore‚ the

of the experiment is to determine the effects of different pH and the rate of reaction on fungal amylase and starch. Introduction The enzyme amylase is found in the human body‚ it catalyses the hydrolosis of internal glycosidic bonds in polysaccharides‚ the breakdown of starch into sugars. Amylase is present in human saliva‚ where it initiates the chemical process of digestion. Enzymes work best at an optimum pH of 7 which is the bodies normal pH. The pH affects the charge of the amino acid

Most often‚ enzymatic hydrolysis is carried out with the enzyme α-amylase from different sources and less often β-amylase is employed. The bacterial α-amylase enzymes attack the polysaccharide molecules in the inner part of the chain. They act on the amylose of starch so that they destroy the spiral of the polysaccharide chain and thus the characteristic blue color with iodine disappears. The viscosity of the starch solutions is quickly lowered. In the beginning dextrines are obtained‚ and if the

particles‚ and give vitality stockpiling. Since your body rapidly processes sugars‚ they additionally give you a fast wellspring of vitality. There are three sorts of sugars. The three different types of sugars are monosaccharides‚ disaccharides‚ and polysaccharides. Monosaccharides otherwise called basic sugars‚ is the least difficult starch structure. When all is said in done‚ the fundamental atomic recipe is n ‚ with n for the most part being somewhere around 3 and 7 in living beings. The most bounteous

Experiment 2: Starch Hydrolysis by Amylase Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2].

Please answer the following questions. Your answer for each question should be a minimum of 150 words (half page). Please number your answers with the number of the question you are answering. 1. Koch was the first scientist to prove that bacteria actually cause disease. He scientifically demonstrated that a disease is caused by a particular organism. He created four general guidelines to aid in identification of disease causing pathogens. These guidelines developed from his work with purified
