Macromolecules of Life Exercise 1: Testing for Proteins In this experiment Biuret Color is added to four substances‚ egg white‚ pepsin‚ sugar‚ and distilled water to test the detection of protein in each substance. Substance Tested Predicted Results Biuret Color & Number of drops added 1. Egg White Change color 5 drops –turned a yellow/light brown 2. Pepsin Change color 5 drops- turned purple 3. Sugar No Change 5 drops-no change in color 4. Distilled Water No Change 5 drops-no

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

Method/Pendulum Exercise Worksheet 1. What is the difference between an observation and an inference? Observations are based on collecting knowledge through our senses. An inference is making an educated guess based on observation. 2. In doing science‚ why are hypotheses either supported or not supported‚ but never proved beyond all doubt? There are many other factors that could be unknown and new data could be found in the future to support or not support a hypothesis. 3. For this pendulum exercise

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
