Test for the Presence of Macromolecules Introduction In this experiment‚ we are trying to identify the presence of macromolecules in certain solutions. As in our daily lives‚ macromolecules are the essential nutrients that we have to take every day‚ therefore we would like to identify the types of macromolecules that contain in some of the food or solution in order to maintain a healthy life. There are four groups of macromolecules which are carbohydrates‚ lipids‚ proteins and

A Macromolecule is a molecule with a very large number of atoms .The word macromolecule is usually used for describing polymers. Molecules that are made up of smaller molecules are called monomers‚ there are also Organic Molecules composed of carbon atoms .The functions of the Four big Macromolecules: First‚ Carbohydrates‚ carbohydrates is the function of being used for energy production during cellular respiration. Second ‚ Lipids‚ lipids are used for four things; insulation and long-term energy

considered alive. These requirements are macromolecules‚ it needs to have metabolism‚ and be able to reproduce. If something has all of these things then it can be considered alive. The first requirement is that it has to have cells. Beings also need macromolecules because they need energy. The four macromolecules are carbohydrates‚ lipids‚ proteins‚ and nucleic acid. Macromolecules are used for energy. A great example of this is humans an their intake of macromolecules. For the average human‚ 55-65% of

composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed. ABSTRACT Tissue types have a variety of compositions‚ and one way to describe these differences is by comparing macromolecule content. The four macromolecules – lipids‚ proteins‚ carbohydrates‚ and nucleic acids – can be quantified and analyzed.

Katherine Waide Mr. Feliciani Honors English 1 Period 4 27 September 2016 Isolation The fiction novel‚ Of Mice and Men‚ written by John Steinbeck follows the captivating story of two migrant workers. The book takes place in the heat of the Great Depression when finding a job was extremely difficult. During this era‚ many people became migrants‚ traveling from farm to farm picking fruit and other crops‚ barely earning enough money to escape starvation. The lack of food‚ clothing‚ shelter‚ and

Introduction The purpose of this experiment was to identify the presence of macromolecules by using various positive and negative controls. The principle building blocks of living organisms are essentially constructed by carbon-containing molecules in cells. (Alberts‚ 2009) The macromolecules including lipids‚ carbohydrates‚ proteins‚ and nucleic acids contribute to the most distinctive properties on living organisms. Macromolecules are known as polymers which are constructed by small organic subunits

ISOLATION OF INDIVIDUAL BACTERIAL COLONIES ON SOLID MEDIA Robert Koch developed a method for isolating pure cultures on solid media in 1883. To this end he added agar (a solidifying agent) to liquid nutrient broth; the nutrient broth supports the growth of a wide variety of microorganisms while the agar provides a solid substrate on which bacteria can be mechanically diluted and therefore isolated as independent colonies representing different bacterial species. The isolation of independent bacterial

Abstract The aim of the experiment is to test the existence of macromolecules which are carbohydrates‚ lipids‚ nucleic acids and proteins in given samples. The first experiment is to test the existence of carbohydrates in starch suspension and potato cell. If carbohydrate is present in starch suspension‚ the solution will turn into dark blue when iodine solution is added. If carbohydrate is present in potato cell‚ starch granules can be seen clearly under microscope when iodine solution is added
