Ester” Introduction: Reaction of a compound with water can result in a splitting, or lysis, of the compound into two parts. Organic molecules containing a group of atoms called an ester can be hydrolyzed by water to form a –COOH group (carboxylic acid) and an HO-- group (alcohol) as follows: RCOOR’ + H2O ( RCOOH + HOR’ This reaction is spontaneous for almost all esters but can be very slow under typical conditions of temperature and pressure. The reaction occurs at a much faster rate if there

the Bradford assay. The identification was used to determine the identity of unknown amino acid #11 and the quantification was used to determine the concentration of unknown protein #11. The identity of amino acid #11 was found to be lysine, and the concentration of protein #11 was calculated to be 0.51 ± 0.019 ug/uL with a 3.67% error, reflecting accuracy in the results. Introduction Identifying amino acids and quantifying protein are common yet important experiments performed in the field of biochemistry

Warfarin is an antagonist of vitamin K used to treat reoccurrence of DVT and pulmonary embolisms. ‘Stenflo & Nelsestuen, 1974’ showed prothrombin ‘the precursor to thrombin’ to contain a number of glutamate residues relating to the amino acid γ-carboxyglutamic acid (Gla). Antagonism in the production of this residue by Warfarin is the key reason for its anticoagulant action and is shown in red in [Figure 1]. Warfarin affects a VKOR enzyme which would normally

Introduction: For this laboratory, we are studying protein adsorption using fluorescently tagged Rh-FGN. To prepare for this study, model sutures of a specific length have been coated in albumin, which allows us to compare the difference between a coated suture and an uncoated suture in regards to “sticky” protein adsorption. Based on the effects of surface energy (γ) on protein adsorption, the uncoated nylon model suture will yield higher protein adsorption then coated suture, since the coated

analyzed for metals, the filter must be prewashed with 1 M nitric acid, rinsed with double distilled water (DDW) and dried before use. Acid washed filters may also be used for other non-volatile extracts. 6. pH meter: Calibrated to within ± 0.05 pH units at 25°C. • Reagents All reagents should be of recognized analytical reagent grade. 1. Nitric Acid, 1M 2. Hydrochloric Acid, 1M 3. Sodium Hydroxide, 1M 4. Glacial Acetic Acid • Extraction Fluid Extraction fluid No 1: Add 5.7 ml of

PBL Write up: Acid-Base This document aims to explain the function of the acid-base equilibrium in place in the human body and to identify potential problems that may occur. Theses processes are tightly linked with the control of fluid levels in the body, this relationship and the function of the water homeostasis system will also be explored. The aim of this write up is to display a full understanding of the learning objectives developed in the PBL session. However by adhering to the original learning

Maci Mullins CHEM2130-001 10/9/2017 Stereochemistry of Bromine Addition to trans-Cinnamic Acid Statement of Problem: What is the stereochemistry for the bromination of trans-cinnamic acid, and how is it formed? Hypothesis: Two forms of stereochemistry can form product for the bromination of trans-cinnamic acid. Cis addition, also known as syn addition, is one way of forming product. This form of stereochemistry allows for the components of the reagent to add to the same side of the double bond

instance, when 0.01 mole of solid corrosive or base are added to refined water, the pH drops to 2 with the corrosive and ascends to 12 with the base. In the event that a similar measure of corrosive or base is added to an acidic corrosive – sodium acetic acid derivation cradle, the pH may just change a small amount of a unit. (1) Buffers are imperative in numerous ranges of science. At the point when the pH must be controlled over the span of a response, the arrangements are regularly cradled. This is

and surface area, greater the surface area, the faster the reaction rate. 4. If HNO3 was used in place of HCl, I’d expect the rate of change to be about the same as both are strong acids. However, if acetic acid (CH3COOH) were to be used instead of HCl, I’d except the reaction rate to be slower as acetic acid is a weak acid and it will dissociate in the water unlike the stronger
