Macro molecules A macromolecule is a very large molecule commonly created by polymerization of smaller subunits. In biochemistry‚ the term is applied to the three conventional biopolymers (nucleic acids‚ lipids‚ proteins and carbohydrates)‚ as well as non-polymeric molecules with large molecular mass such as lipids and macrocycles. The individual constituent molecules of macromolecules are called monomers(mono=single‚ meros=part). Usage The term macromolecule was coined by Nobel laureate Hermann

Exercise 4.4: Identification of Macromolecules in Household Substances The purpose of this lab is to determine the presence of glucose‚ starch‚ and protein in various samples through standard tests. Solution 1: Formula I believe formula will test positive for sugar and protein since it is supposed to be a nutritious‚ balanced drink for infants. Materials and Methods: Please refer to the Biology 1406 Lab Manual Pg. 43 Test For | Coloration/ Appearance of Positive Control | Coloration/

bond covalently. In other words‚ the electrons in the valence‚ or outermost‚ shells are shared between the atoms. If a molecule contains a plethora of nonmetal atoms often bonded in complex rings and chains‚ it is deemed a macromolecule. According to Volesky‚ the macromolecules with carbon rings and

structure which is why they function in these ways. These molecules are known collectively as macromolecules‚ these molecules are grouped into four main categories which each have there own structure. These structures are the key to the macromolecules functions as each of them do a specific task in the body. Macromolecules are grouped into carbohydrates‚ nucleic acids‚ proteins‚ and lipids. In most cases macromolecules are polymers‚ which is a long molecule which are made by linking together a large number

Macromolecules Biologically‚ there are four general types of macromolecules or biomolecules. They are carbohydrates‚ proteins‚ lipids and nucleic acids. Each of these plays an important role in maintaining life among living creatures and each is a piece of the elaborate puzzle of metabolism. Each has a different chemical composition and interacts with other molecules differently. Most of these biomolecules come from food sources and we are therefore already familiar with them. Without a

Deoxyribonucleic acid (DNA) is the fundamental molecule of life encoding the genetic code for the development and functioning of every living organism and a large variety of viruses. RNA‚ proteins‚ and DNA are the main macromolecules‚ which are necessary for every form of life. The genetic system is encoded in the form of a sequence of nucleotides (guanine‚ adenine‚ thymine‚ and cytosine)‚ which are denoted by the letters G‚ A‚ T‚ and C. Most DNA molecules consist of double-stranded helices‚ composed

BIOLOGY LAB REPORT PRACTICAL M1 TESTING FOR MACROMOLECULES Title : Testing for Macromolecules Abstract : To test for macromolecules (carbohydrates‚ lipids‚ nucleic acids‚ and proteins)‚ iodine solution‚ alcohol‚ aceto-orcein stain and copper sulfate solution are used. The conclusions for all of the tests are positive. Introduction: A) Carbohydrate (starch) Carbohydrates are chemical compounds that contain oxygen‚ hydrogen‚ and carbon atoms. They consist of monosaccharide

Title: Hydrolysis of macromolecules Abstract: This lab was designed to teach the process of “hydrolysis”‚ a chemical reaction in which water is added to a polymer‚ breaking its bonds and forming smaller molecules. A hydrogen cation and a hydroxide anion (which once formed water) break apart and attach themselves to the ends of shorter polymers. Hydrolysis plays an important role in our lives and in the lives of every living thing on earth. Living organisms rely on digestion (hydrolysis)
