Myristic acid

trimyristin was converted to myristic acid. Background: Solid-liquid extractions are common in everyday life and are important in a chemistry laboratory because they involve the separation of an individual compound from mixtures. Using solid-liquid extraction, which separates compounds based on solubility. Trimyristin was isolated from nutmeg using diethyl ether because trimyristin is a nonpolar compound that readily dissolves in diethyl ether, which has a low polarity. To concentrate the solution containing trimyristin distillation was used, which separates compounds based on boiling…

The Rf values were obtained by reacting the lipids on the TLC plates with iodine, to visually show how far the lipids moved up the TLC plate. For the identification of the amount of lipids in milk, the milk was combined with an organic mixture of CHCl3/MeOH, to isolate the lipid layer. By centrifuging the organic solvent with milk the heavy lipids sink to the bottom while the water layer which contain water soluble carbohydrates, peptides and small amino acids float to the top. Since the organic…

Soap may be made up from either saturated fatty acids and/or unsaturated fatty acids. The most common saturated fatty acids used in soap are, “lauric acid, myristic acid, palmitic acid and stearic acid” ( Michelle 2014). If a more effective clean is desired then, using a saturated fatty acid is the way to go because they get rid of oils better. Due to this, soaps made up of saturated fatty acids are less prefered for skin because it will take away the natural oils produced by your skin. These…

stimulant (British Pharmacopoeia 2009). • Methyl paraben was generously donated by Arab Pharmaceutical Manufacturing Company. Methyl paraben is methyl-4-hydroxybenzoate, prepared by the esterification of p-hydroxybenzoic acid with methanol. It occurs as colorless crystals or a white crystalline powder. It is odorless or almost odorless and has a slight burning taste (Rowe et al., 2009). Methyl paraben is very slightly soluble in water, freely soluble in alcohol and in methanol (British…

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…

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 (H2O),…

than anything else. It is important to take care of the body from any harm. One thing that the body is capable of is maintaining pH levels and buffers. A pH is the power of hydrogen and buffers prevent extreme shifts in pH. The blood has a specific type of buffer that is maintained at pH level of 7.4. If the buffers shifts and levels of pH 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…

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, is represented as moles of the measured substance divided by the volume in dm3. It is a value of the amount of substance in a…

INTRODUCTION : The concept of dentin adhesion presently used involves the 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…

occurring all over the world, from deforestation to excessive water pollution. One urgent issue facing the world today is freshwater pollution and the negative effects it is having on freshwater aquatic 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…
