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

The density was not useful due to an error of the machine but the boiling point and refractive index

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

As an eight-year-old pipsqueak who was regularly pitted against the twelve-year-old Goliaths of Albuquerque’s 12U tennis division‚ losing 0-6‚ 0-6 became a natural part of life‚ and I hated it. In fact‚ my tournament to-do list consisted of a dreadfully long car trip‚ suffering defeat upon defeat to another unnamed middle-school giant‚ and then drowning myself in a sea of tears while my dad lectured me about "unforced errors" on the trip home. As a result‚ I started to run away from tennis. I performed

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)

I’m not as glamorous as I might seem. I’m just an ordinary student in 10th grade‚ who likes to learn things. Others may be more charismatic or handsome‚ but I have something that they do not. I posses an essential life skill; initiative. You (as the readers from the National Honors Society) may think that what I am saying is absurd‚ but I am here to prove my worth one paragraph at a time. I am a well educated individual who has repeatedly demonstrated initiative and high standards of reliability

OBJECTIVE The main objective of this experiment is to carry out qualitative analysis to identify metal cations in unknown solution 1. INTRODUCTION An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed
