an 0.1 M solution of NaOH. This was done by diluting from the 6 M solution that was provided. Next‚ 0.715g of KHP was weighed using the glazed paper and the triple beam balance. The KHP was then transferred to the 250 mL Erlenmeyer flask. Using a graduated cylinder‚ 50 mL of deionized water was measured and added to the flask. The KHP was dissolved in the water‚ and few drops of phenolphthalein were added. Moreover‚ the burette was rinsed with deionized water‚ then with NaOH solution. Then‚ it was

Hoitt CHEM 105 Lab 11/29/2012 Lab # 11 – Acid - Base Titration Introduction: The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions are made up of solvents and solutes

EXTRACTION AND ISOLATION OF PROTEINS Background of the experiment Pure proteins are not readily available for study or use. There are certain methods that should be done in order to obtain proteins from its sources. The objective of this experiment is to isolate casein from milk and albumin from egg and to identify and explain the principles behind the methods employed for protein extraction. Results and Discussion There are many possible sources where we could get proteins. It can be from plants

BASICS OF INTEREST RATE SWAPS A swap is an agreement between two institutions to exchange future cash flows. Suppose there is a bank receiving fixed 8% return on 2 year money lent. This bank can swap its revenue stream against another firm’s variable rate 2 year money. In practice swaps tend to be more complicated and can involve more simultaneous variations of interest rates and currency as well. When settled‚ only the differential between the would-be payments are exchanged between two parties

An old well-known method to stabilize a peptide sequences or protein motifs is N-terminal and C-Terminal modification to resistance against exo-nucleases cleavage. Due to its feasibility‚ we decided to perform this type of modification in order to stabilize synthesized sequences based on previous protocols. Understanding the appropriate compound and choosing the way of performance‚ were sensitive and definitely time consuming. Finally‚ N-terminal modification with 5(6) Carboxyfluorescein (FAM) in

NaOH Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance

Topic: Protein Folding and Molecular Chaperones - What happens when proteins fold incorrectly? Consequences of Protein Misfolding Vina Ong 20554965 Section: 126 Ares Rao A protein is made of amino acids that supply cells with their formation and execute most of their activities. Proteins can easily be denatured and refolded which happens spontaneously as the denaturing solvent is added and removed‚ under the proper circumstances. (Alberts‚ 2014) Since they can be easily denatured there

Proteins are polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary‚ secondary‚ tertiary‚ and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from
