Chemical Composition of Cells

CHEMICAL COMPOSITION OF CELLS BY OLADIWURA FAKIYESI BIOLOGY 101 science laboratory REPORT INTRODUCTION each(prenominal) cells turn back cardinal major types of macromolecules: carbohydrates, lipids, Nucleic acids, and proteins.   to each one macromolecule is a large polymer that is formed from constituent molecules cognise as monomers. Proteins, for instance, consist of a linear chain of aminic acids united together by peptide bonds (Murray et al., 2006). Carbohydrates are formed from monosaccharides and disaccharides joined together by glycosidic bonds (Varki et al., 2008). Lipids, such as fats and oils, are derived from glycerine combined with three fatty acids by ester bonds (G.P. Moss, 1976). And lastly, nucleic acids are   imperturbable of nucleotides; each of which contains a pentose sugar, phosphate group, and nucleobase (Mullis, 1993). In this experiment, three of the four macromolecules-- proteins, carbohydrates, and lipids volition be studied.

Various chemical shields can be used to celebrate the presence of each of these molecules. Most of the rills touch a illusion change visible to the eye. If a colour in change is observed, the test is considered positive. If the color change is not observed, the test is negative, indicating that a concomitant molecule is not sit. In both the chemical tests we go out be performing, we will also be using two controls. The negative control will be a try out of distilled water (which should not! contain any macromolecules). For the occasion tally to the detection of proteins, it is predicted that the albumin will contain traces of protein due to it existence known to be present in egg whites (an  subtle source of protein). In the procedure correlated to the detection of amylumes, it is predicted that the murphy will contain traces of starch due to the potato existence the root of a plant.
