Protein has high molecular mass long chain polymer composed of α-amino acids. Proteins are constituents of cells and hence present in living bodies. Proteins contain carbon hydrogen nitrogen oxygen and sometimes phosphorus and sulphur.
Proteins questions and answers. The article in your hand Questions and answers about proteins primarily meant for graduate and postgraduate students of Chemistry with the intention that they could show better performance during various competitive examinations and interviews held for Civil and Military Services. At the same time it is equally useful for those who desire to be well informed in.
Chemistry and Identification Proteins make up the bulk of all solid material within your body and the bodies of other animals. Your muscle skin hair and inside organs are largely protein. Proteins even provide the framework for you bones.

To the test solution add a 14th volume of Ninhydrin solution and boil and cool. Formation of a blue color indicates the presence of protein. Mix the sample solution with concentrated nitric acid boil and cool.
Then add 40 sodium hydroxide drops. Formation of orange color solution indicates protein. Take 5 ml of protein solution or the suspension of gram flour legumes or soya bean in water in a test tube.
Add 2 to 3 drops of Millons reagent 10 mercuric sulphate in 10 sulphuric acid called first solution. Nitric acid and water in the proportion of 1. 2 4 called second solution.
Chemistry Identification Lab Name. Today scientists use a combination of biology and chemistry for their understanding of life and life processes. Thus an understanding of some chemistry of living things is necessary.
Carbohydrates make up a large group of chemical compounds found in cells. 0023 eScience Labs LLC 2014 Part 2 Show table or graph or pictures of your lab work. Biology 102103 Lab 2.
The Chemistry of Life INSTRUCTIONS and submit it via the Assignments Folder by the date listed in the Course Schedule under Syllabus. To conduct your laboratory exercises use the Laboratory Manual located under Course Content. To test the presence of carbohydrates proteins fats and oils in the given food sample first the extract of the given foodstuff should be prepared.
Dry the given foodstuff in the mortar with a pestle or by boiling with minimum quantity of water extracting with a small quantity of an organic solvent after grinding the foodstuff. In this lab with the use of indicators as chemical detection tools you will analyze a variety of foods for the presence of nutrients. Detection is based upon observing a chemical change that takes place most often a change in color.
Proteins are organic molecules that form muscles transport O2 hemoglobin and act as hormones and enzymes. Most importantly proteins determine how our bodies look and function. Their building block is the amino acid.
Proteins are made of amino acids combined. Chemistry and Identification I. Amino acids building blocks of proteins Proteins are complex molecules made up of smaller molecules called amino acids.
In todays lab you will study carbohydrates monosaccharides disaccharides. Polysaccharides proteins and lipids. Most of the biochemical tests used in the following exercises rely on indicators chemicals that change color when a specific substance is present.
Protein folding and denaturation. The structure and function of globular proteins. Enzyme structure and function.
Central dogma of molecular biology. Central dogma of molecular biology. Our mission is to provide a free world-class education to.
Answer the above numbers 1-4 with complete paragraphs. Think about the purpose of the lab and why you were asked to participate in the lab what did you learn. A conclusion is considered INDEPENDENT work.
DO NOT share your thoughts and conclusion with your lab table group. Turn in the entire lab checking the data table and units. 2-22-2016 Biology 1406 Lab Report 1 Professor Kintsley Identifying Biomolecules Purpose This lab exercise is intended to test the known and unknown substances and figure out what biological molecules are in each substance.
The three bio molecules tested are carbohydrates proteins and lipids. This is done by using separate reagents for each individual test which solutions. Clinical chemistry is the branch of laboratory medicine that focuses primarily on molecules.
The tests in a clinical chemistry laboratory measure concentrations of biologically important ions salts and minerals small organic molecules and large macromolecules primarily proteins. See Section 6 for more detail about specific analytes. Will also find it difficult to answer the prelab questions that must be turned in each day.
The biochemistry laboratory course like all laboratory courses is an exploration of procedures. This means that in order to get full benefit from the course you will need to read the manual and you should participate as. Amino Acids Lab Report Introduction Amino Acids are the building blocks of proteins.
They contain the four basic elements nitrogen hydrogen carbon and oxygen. An amino acid structure begins with the central carbon in the middle. This carbon atom forms a bond with the amine group NH 2 the carboxyl group COOH a hydrogen atom and a variable R group.
Answer the following in complete sentences. What happens when a protein denatures. Explain why proteins might denature at different temperatures.
Which method appeared to have the most dramatic denaturing affect on egg albumin. Why do you think this method had a greater affect.
