The B vitamins are an essential part of our functioning immune system. It is important for health reasons to get a healthy amount. Many people don’t know when they are deficient in a B vitamin. B12 specifically has a major affect on individuals who are deficient. Did you know that almost 40% of Americans are B12 deficient? Vitamin B12 (cobalamin) is a water-soluble vitamin whose main function is to regulate normal functioning of the brain, nervous system, and formation of red blood cells…

The amino acid, homocysteine, is basically a cysteine with an added methylene bridge. Methionine, an essential amino acid, gives rise to homocysteine, a sulfur-containing amino acid, through the methionine cycle. Methionine is converted to S-adenosyl methionine (SAM) when an adenosine group from ATP is added on to activate methionine’s methyl group. SAM is a methyl donor that is a substrate used in many reactions. When it donates the methyl group, SAM is converted to S-adenosyl homocysteine…

oxygen3. Serratia Marcescens is a gram negative bacterium. Gram negative bacteria have a thin cell of a single layer of peptidoglycan that is enclosed by an outer membrane. The outer membrane is surrounded by special phospholipids composed of fatty acids called lipopolysaccharides that are attached to a glucosamine…

is a neutralization reaction. A neutralization reaction is a chemical reaction in which an acid and a base react to form an ionic compound (a salt) and water; the resulting pH is closer to 7. The general chemical equation for a neutralization reaction is: Acid + Base Water + Ionic Compound This can also be considered as a double displacement reaction. However, since the reacts are an acid (carbonic acid) and a base (sodium hydroxide) and the products are a salt (sodium carbonate) and water…

go to 7 or 7.8, it can be deadly. The blood buffer contains carbonic acid which dissociates into bicarbonate acid and hydrogen ions. This equation can also be reversed; it is a chemical equilibrium. If the hydrogen ions rise, bicarbonate accepts the hydrogen ions and the equilibrium shifts left thus making the blood acidic. When the blood becomes acidic, acidosis…

Introduction: Many chemical compounds are broken down into two very distinct categories: acidic or basic. Acidic, based on the Bronsted-Lowry Theory, is defined as a proton (H+) donor. An equation exemplifying an acid dissolving in water is: HCl (g) H2O H+ (aq) + Cl- (aq) A base, based on the Bronsted-Lowry Theory, is defined as a proton (H+) acceptor. An equation exemplifying a base dissolving in water: NaOH (s) H2O Na+ (aq) + OH- (aq) Molarity, also known as the concentration…

nanomechanical retention which is due to polymerisation of hydrophilic monomers around acid exposed collagen fibres.1 The entanglement of these monomers within the exposed collagen fibres gives rise to the so called Hybrid layer , which is also referred as Resin infiltrated Dentin layer.2 The presence of hybrid layer is important for attainment of a leakage free interface between the cavity walls and resin composite.2 After acid etching, the demineralized collagen matrix is present in a…

life. Pollution is creating a positive feedback loop in our freshwater aquatic life, including the killings of many of freshwater wildlife. Through the analysis of several different articles and books, this review will look over how eutrophication, acid rain, and heavy metal pollution effects freshwater aquatic life. Eutrophication is a process in which there are extra fertilizers, and other types of materials which runs off into…

on it which would have been removed with the stick. It is less clear why the benzoic acid was overproduced. Some of the organic layer may have been drawn off with it, but the vacuum filtration should have left only the benzoic acid. There could have been an error in weighing the filter paper before the procedure. There also could have been contaminants in the basic extract, causing more than just the benzoic acid to be filtrated. There is also the chance that too much starting material was…

Dianne Termine Honors Chemistry Period 5 Group: 22 Topic: Dissolving Alka-Seltzer in Different Liquids Due Date: September 30, 2016 (2) Background Research The topic of this experiment is investigating and researching whether different properties in different types of liquids affect the amount of time it takes for an Alka-Seltzer to dissolve. The independent variable would be the amount of liquid being used to dissolve the Alka-Seltzer pill. The dependent variable would be the amount of…
