indicator. If the product of food contained the macromolecule that was tested for it would of showed if there was any difference from the two test tubes. The results of the lab seemed mostly reasonable. The only result that didn’t seem right was the cheese. Cheese is a dairy product which contains proteins however‚ the Big Macs cheese didn’t have proteins. Other than that the lab results looked right. The food product would match up with the correct macromolecule.

BIOL 130 Lab Report Identifying Two Macromolecules - Carbohydrates and Proteins 9/26/2013 [Type the company name] INTRODUCTION As the name suggests‚ macromolecules are large molecules that make up more than 90% of the total cell mass. These biological macromolecules vary greatly in size - from several hundred to several hundred million molecular weight units - and are made up of monomer units. There are four major classes of biological macromolecules: proteins‚ carbohydrates‚ lipids

universe‚ people have spent centuries searching for the explanations to how life existed on this planet. Indeed‚ the atomic structures that form the basis of matter still must exist in order to develop life‚ but what significant atomic 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

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

Laboratory Report SCPB111 Principles of Biology Faculty of Applied Sciences Pearson Institute of Higher Education 14 March 2018 Abstract Biological molecules are part of Introduction Biological molecules are formerly known as macromolecules. 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 removed during the formation of bonds (Wayne Huang‚ 2015). Biological molecules

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 in Food INTRODUCTION The most common macromolecules found in living organisms are lipids‚ carbohydrates‚ proteins‚ and nucleic acids. (Hillis et al 2011). Macromolecules are normally containing two or more monomers in them and their main functions are to store energy. Starch is a huge molecule made up of hundreds of simple sugar molecules (such as glucose) connected to each other. Most foods are known to be combinations of macromolecules. METHODS The tests performed were iodine

The universe is comprised of one hundred eighteen elements that either occur naturally or as laboratory productions. Of these‚ six of them are crucial to the vitality and sustainment of life. These include carbon‚ hydrogen‚ nitrogen‚ oxygen‚ phosphorus‚ and sulfur. For a molecule to be considered organic‚ it must contain rings or chains of carbon (Volesky). A molecule is a chemical species encompassing several or many nonmetal atoms. The atoms bond covalently. In other words‚ the electrons in the
