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

Abstract: We tested five common food items to determine which macromolecules were present. We tested for the macromolecules of simple and complex carbohydrates (sugars and starch)‚ lipids‚ and proteins. The foods tested were coconut milk‚ karo syrup‚ potato chips‚ peanut butter‚ and banana baby food. We hypothesized that coconut milk would contain all four types of macromolecules‚ karo syrup would only contain simple sugars which are monosaccharides and/or disaccharides‚ potato chips would contain

Semester Writing Assignments This semester‚ you will have several writing assignments‚ the first of which you’ve already completed! For each of these assignments‚ you are expected to put forth both thought and effort. Most importantly‚ remember that these papers are assigned to you‚ so they should be in your own words. 1) Two of the assignments due in this course are directly related to one another: Part 1. Write a brief essay that addresses these questions: What does biology mean

Throughout this article it talks about why you should study biological macromolecules‚ how mass spectrometry is a method used to identify molecules‚ how each scientist contributed to the methods‚ and the NMR for biological macromolecules. Studying biological macromolecules can help many people understand all living organisms. All living organisms contain the same type of large molecules and macromolecules. Everything in the cell is controlled by nucleic acids. Cells also have a variety

Summary: Experiment 9 is conducted to identify the importance of intermolecular forces and how they affect molecules. Intermolecular forces are forces between molecules that determine whether the molecule is a solid‚ liquid‚ or gas under standard conditions. In our lab‚ we measured the maximum and minimum temperature reached and time it took to reach it of alcohols and alkanes. In addition‚ we measured the vapor pressure of the liquid at different temperatures. Through Experiment 9‚ we concluded

structures are there to make this happen? Respectively‚ a much broader scale can be utilized to assemble the main components for life‚ which they are called macromolecules. Macromolecules are very large molecular structures that contain carbon and are the vital organs for the structure and function of all living things. The first macromolecule that will be addressed is the carbohydrate. Carbohydrates are found in most plants and animals and are usually represented as sugars‚

diverse macromolecules are different because of the structure of these respective monomers. An exceptionally large assortment of macromolecules gets produced. While the polymers are accountable for the molecular exceptionally of an organism. The joint monomers are virtually universal. The difference in the form of the macromolecules are responsible for the molecular diversity. The variation that occurs both within an organism and among plants can be traced to the difference in macromolecules. Also

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

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
