1) A peptide‚ KKDSRHSTTR is tightly bound to a negatively charged ion exchange column. The column is washed with a pH 7.2 HEPES buffer (50 mM) and the peptide does not elute. Suggest two ways that you can change the buffer that will make the peptide elute from the column. 2) What amino acid(s) is/are involved in crosslinking polypeptide chains. How can these crosslinks be cleaved and prevented from reforming? 3) A polypeptide is subjected to the following degradative techniques results

RNA Analysis 1. The color result is light brown. 2. A positive Biuret test indicates the presence of proteins in the filtrate. Biuret is used to test for proteins. It is a light blue color and changes to purple in the presence of protein‚ a polymer made of amino acids. It will not change color when only amino acids are present. 3. What type of molecules present in the suspension is hydrolyzed by the mild acid treatment? 4. The products of hydrolysis are peptones‚ peptides‚ and amino acids

The reader can gain a deeper understanding of the power struggle between Cameron and his Dad in Going Bovine by Libba Bray by looking through the marxist literary lense. Throughout the book‚ Cameron’s Dad has always been in charge and rules the family through an iron grip. While Cameron’s Dad is cutting the grass‚ Cameron states “Our eyes meet for a nanosecond‚ and then Dad stoops to examine a particularly hearty clump of weeds. As I back the Turdmobile down the driveway‚ he’s running the mower over

Genetics: In the primordial period‚ simple molecules were formed from atoms and from these molecules‚ macromolecules were formed. These macromolecules formed life and all living organisms. The classical genetic and heredity observations in the 19th century started the search for the origin of life. The transforming

Introduction: Dependence of Methane Production on Ambient Temperature in Bovine Waste The purpose of this experiment was to determine the effect of temperature in bovine waste on the amount of methane evolved. The hypothesis stated that the bovine waste heated to 48.9oC would produce the most methane. The manipulated variable in the experiment was the temperature of bovine waste. The responding variable was the amount of methane evolved from the waste. The experiment can be applied to real world

Biological chemistry 1B Experiment 1: Thin layer chromatography [TLC] Aim The aim of this experiment is to apply the technique of TLC to first separate out a mixture of coloured dyes and then to do the same for selected range of amino acids. Procedure 2 MMs of each different colour were collected into separate beakers. Approximately 5 drops of water is added to each of the beakers containing the MMs and the tablets were stirred until
