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

Identification of Macromolecules Introduction The purpose of this lab is to test for the presence of macromolecules in various foods. Tests are performed to describe the basic structure of proteins‚ lipids‚ glycerides‚ and carbohydrates. We are to recognize the positives and negatives in these macromolecules. Also we are to identify the roles that proteins‚ lipids‚ minerals‚ vitamins‚ and carbohydrates play in the body’s construction and metabolism. Procedure / Results 5.1 Carbohydrate

Chapter 5: The Structure & Function of Macromolecules Reading Guide Part 1: Carbohydrates: Read pages 68-74 and complete the following questions. 1. Define the following: a. monomer-repeating units that serve as building blocks of polymers b. polymer-long molecule consisting of many similar building blocks linked by covalent bonds c. dehydration synthesis or condensation reaction-monomers are connected by a reaction in which two molecules are covalently bonded‚with loss of water

Macromolecules are molecules that are large and essential for life. They consist of carbohydrates‚ nucleic acids‚ proteins‚ and lipids. Carbohydrates are molecules that are composed of monosaccharaides. Carbohydrates include cellulose‚ starches‚ and sugars. Two tests may be used to determine the presence of the carbohydrates. Those tests are the Benedict’s test and Lugol’s Iodine Test. Proteins are another category of macromolecules. The protein is a type of macromolecule that carry out many processes

Wilson Grand Canyon University Professional Research Project NRS-441V March 19‚ 2013 Identifying a Problem The clinical environment that I previously worked in was a correctional institution. During the time that I worked in corrections I encountered several inmates that had HIV. It was this environment and the experience that I received this idea and it is what gives me the inspiration to build a proposal for change. Within this system is where I discovered

Identifying themes in novels A theme is like a symbol in that it is an element that an author can use to add depth of meaning to a novel. 1. Themes are expressed and emphasized by the way the author makes us feel. By sharing feelings of the main character you also share the ideas that go through his mind. 2. Themes are presented in thoughts and conversations. Authors put words in their character’s mouths only for good reasons. One of these is to develop a story’s themes. The things

Keith Shearer Lab Group 3 January 19‚ 2015 Objective Is to measure various food items and become familiar with different energy units like calories and joules. Also‚ we will be using simple household products and follow the standard safety procedures of this lab. Materials Procedure First‚ use a digital scale to determine the empty weight of the 100ml beaker. The‚ you are going to fill the beaker half way with water (approximately 50ml) and weigh it again. Take the water and beaker weight

TA: Gia Hoang Lab 1: Effect of pH on a Food Preservative 9-1-2011 Purpose The purpose of this lab was to determine if a new substance forms when sodium benzoate is placed in a simulated stomach acid. Theory Benzoic acid can be found in a wide variety of plants. It is used as a natural preservative in many foods. Sodium benzoate‚ the salt of benzoic acid‚ has become a more popular choice as a food preservative because it is more soluble in water than benzoic acid. Many food items found today
