that is caused by organic polymer materials such as plastic on the environment thereby having harmful effect on human being is known as plastic pollution. Plastic mainly can be divided in two broader classifications namely. * Thermoplastics * Thermosetting plastics Both these varieties of plastics are not biodegradable that cannot be acted by micro organisms leading to the breakdown of the molecules. Generally most of the organic materials such as proteins in human and animal systems

Sarah Khan Bivins-5th April 20th‚ 2013 Protein Synthesis Every day‚ you take in an abundance of different biomolecules; one of them being proteins. Have you ever wondered how proteins are made? They don’t just grow from a tree or fall from the sky‚ they are made through a process called protein synthesis. Protein synthesis is broken up in two two steps: transcription and translation. Transcription starts inside the nucleus when the DNA is unzipped by helicase. Following that‚ the mRNA nucleotides

Laboratory Exercise #3 Measuring Protein in Solution Abstract The purpose of this lab was to learn about the Biuret assay reaction to determine if it can detect proteins and amino acids; also‚ to understand the process of “salting out” proteins and how to determine the amount of protein in a solution. In order to do so‚ egg white and ammonium sulfate were mixed on ice and then put into the centrifuge. After PBS was added‚ the amount of protein could then be determined. After that‚ 14 test tubes

Proteins are also essential nutrients for the human body. They are important in body tissue‚ and can also serve as a fuel source. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. We need protein in our diet to help our body to repair cells and make new ones. The human body needs a lot of amino acids to maintain good health. Protein is also important for growth and development in children‚ teens‚ and pregnant women. Proteins are polymer chains

important food nutrition is protein. There is no high protein food‚ even if eating more carbohydrates‚ exercise how hard‚ it is difficult to get muscle full of body contours. The protein is not only the nutrients needed for muscle development‚ but also the body after the strenuous exercise to repair the damage necessary. Therefore‚ high-protein foods should be included in the daily diet. 1‚ eggs are the most natural‚ the most useful food to build muscle. They not only contain rich protein‚ but also

Abstract The experiment‚ entitled Extraction and Characterization of Proteins‚ aims to isolate casein from milk and albumin from egg; to explain the methods employed for protein extraction; to apply spectrophotometric methods in characterizing and quantifying extracted casein and albumin. The experiment was divided into 2 parts; the extraction of Albumin from egg and the determination of protein concentration via the Warburg-Christian method and Bradford Assay method. In the first part‚ egg

COMPANY PROFILE: Murali Krishna polymers are established in the year 1997. It involves in the operations related to production of plastic bags and flexo printing. The owner of this company is M.S. Muralidhar. He identified the growth in the usage of plastic bags across the country. The idea of starting a firm with manufacturing of plastic bags intrigues him. He found the inappropriate number of plastic producing firms irrespective of its potential market in southern India at that time. As a result

The Protein Data Bank Assignment: Glucansucrase After I came to America‚ I have already met my dentist many times. Although I brush my teeth three times a day‚ use floss correctly and meet dentist every year‚ I don’t know why my teeth keep in trouble and get cavities again and again. I really want to figure out why the bacteria from my mouth cannot be removed. When I am finding some protein‚ I found that Glucansucrase which is related on the issue of tooth decay. I think Glucansucrase

Experiment 2: Food Tests Objective * To study the presence of reducing sugars. * To study the presence of protein. Introduction In this experiment‚ glucose‚ maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are
