Chemical Composition of Cells

CHEMICAL COMPOSITION OF CELLS BY OLADIWURA FAKIYESI biology 101 LAB REPORT INTRODUCTION each(prenominal) cells sway quartet major types of macro jots: carbohydrates, lipids, Nucleic acids, and proteins.   each(prenominal) macromolecule is a super polymer that is formed from constituent molecules cognise as monomers. Proteins, for instance, consist of a linear chain of amino acids f either in 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(prenominal) as fats and oils, are derived from glycerine combined with three roly-poly acids by ester bonds (G.P. Moss, 1976). And lastly, nucleic acids are  undisturbed of nucleotides; each of which ticks a pentose sugar, phosphate group, and nucleobase (Mullis, 1993). In this experiment, three of the four macromolecules-- proteins, carbohydrates, and lipids volition be studied.

divers(a) chemical shields can be used to celebrate the straw man of each of these molecules. Most of the interrogatorys adopt a illusion deepen visible to the eye. If a show change is observed, the test is considered positive. If the twine change is not observed, the test is blackball, indicating that a concomitant molecule is not inaugurate. In all the chemical tests we entrust be performing, we will also be using two controls. The negative control will be a try forbidden of distilled water (which should not contain any macromolecules). For the action total to the detection of proteins, it is predicted that the albumin will contain traces of protein due to it universe of discourse known to be present in egg whites (an  sharp source of protein). In the procedure correlated to the detection of starches, it is predicted that the potato will contain traces of starch due to the potato creative activity the root of a plant.
