Macromolecules are large molecules that are formed from smaller molecules called monomers (Ellisman‚ 2014). They are formed by dehydration reactions‚ in which a water molecule is

INTRODUCTION Macromolecules are highly important organized organic molecules that are found within living cells. These biological molecules help the body execute precise important tasks. There are four types of macromolecules: carbohydrates‚ lipids‚ proteins and nucleic acids. (Karp‚ 2010) This specific experiment showcased the identification of different macromolecules using three different testing methods. Carbohydrates‚ sugar molecules‚ are known as “fast fuel” in the body‚ and they contain

Identifying Biological Molecules with Colorimetric Chemical Tests Objectives Perform a series of accurate tests on biological molecules to detect the presence of carbohydrates and proteins‚ as well as the action of an enzyme on specific molecules. Introduction Unknown biological molecules can be correctly identified using various tests‚ including colorimetric chemical tests. Colorimetric tests are when a chemical reagent‚ such as Benedict’s‚ is used on a substance or solution and a certain

ENERGY RESERVES OF MACROMOLECULES SUMMARY This experiment was conducted in order to show the energy received from the food that humans eat on a daily basis. The energy that is required by the human body to perform chemical reactions is obtained from the chemical bonds that formed between the atoms in the molecules. To calculate the amount energy‚ types of food products were burned underneath a test-tube filled with water. The temperature rise gave an estimate of the energy released per gram.

I. Abstract The common organic compounds provide us with nutrients are sugars and starches‚ carbohydrates‚ proteins‚ and lipids. In this lab‚ qualitative tests are performed to identify the presence of organic compounds in food using indicators‚ chemical substances that react in a certain way when a particular substance is present. We put one indicator into the each test tube containing different solutions at a time to see what organic compound is present. The color change in the indicator tells

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

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

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.

Mrs. Feeney Biology 9 October 16‚ 2012 Identifying Organic Compounds Objective: To use indicators to test for the presence of organic compounds in certain substances. Theory: Major types of organic compounds in some common foods are Lipids‚ Carbohydrates‚ and Proteins. An indicator is a chemical compound that changes color and structure when exposed to certain conditions and is therefore useful for chemical tests. The purpose of using distilled water as one of the substances in the test
