Dying hair is a practice that has been around for thousands of years. Ancient civilizations began dying hair through use of plant pigments that many cultures continue to use today. In Western culture, hair dye usage has increased steadily from the 1960s, and is now widely popular, as well as socially accepted. Despite the significant percentage of the human population that uses hair dyes on a regular basis very little research has been done on the effects of the dye on human health (Nohynek…

of the imines you have met before (in Chapter 14, for example), have been unstable intermediates in carbonyl group reactions, but in pyridine we have a stable imine—stable because of its aromaticity. All imines are more weakly basic than saturated amines and pyridine is a weak base with a pKa of 5.5. This means that the pyridinium ion as about as strong an acid as a carboxylic acid. Pyridine is a reasonable nucleophile for carbonyl groups and is often used as a nucleophilic catalyst in acylation…

The experiment made use of two reactions in synthesizing 1-phenylazo-2-naphtol, also known as Sudan-1. The first is the diazotization reaction in which a diazonium salt is formed from the conversion of primary aromatic amines, such as aniline, to compounds with the nitroso functional group using a nitrous acid, such as HNO2. The diazonium salt was then used as an electrophile in a coupling reaction with an aromatic compound, β-naphthol. Recrystallization was conducted and yielded 0.18 g of a…

Desoxyn (Methamphitamine ) Classification: CNS Stimulant/Anorexiant/ Sympathomimetic MW: 149.237 g/mol pKa: 9.87 (at 25 °C) Chemical Formula: C10H15N IUPAC Name: (2S)-N-methyl-1-phenylpropan-2-amine Description Methamphetamine comes under category of amphetamine type stimulants. Methamphetamine is an Amphetamine Anorectic and Central Nervous System Stimulant. Other than clinical usage as an oral form or Intravenous form, methamphetamine has been highly abused as street drugs by…

aspartic acid, a polar charged amino acid and phenylalanine, a non-polar charged amino acid. The chemical formula of this compound is C14H18N2O5 and the molecular weight is 294.3 g per moles. The functional groups of aspartame are one carboxyl group, one amine group, one amide group, one phenyl group, and one ester group (methyl ester). Although aspartame has aspartic acid in its structure, it is not very soluble in water. The solubility of aspartame depends on pH and temperature. Basically, the…

Through the process of staining and stimulations in experiments, researchers have now identified more than 100 unique chemical messenger types which can further be classified in several ways as such- amino acids, gasotransmitters, monoamines, trace amines, peptides, purines etc. However, in my paper I would like to mainly focus on the most prevalent neurotransmitter “Glutamate” which is responsible for postsynaptic…

Hair coloring is when hair dye/bleach is used to change the color of one’s hair. There is a certain chemical process involved in dying ones hair. Hair coloring has been used all throughout history and has solved many social and personal problems. However, coloring ones hair also has positive and negative side effects as well as implications through an ethical point of view. Hair coloring is the practice of changing ones hair color, whether its through bleaching or dying with different colors,…

Flow batteries have been around since the 1970’s this technological advance in the field of energy storage and acts as a fuel cell which can provide a new and efficient energy supply. One of the biggest advantages of flow batteries is that they can practically in an instance recharge just by replacing the electrolyte liquid,while this happens it is recovering the spent materials for recharge. Several different flow batteries have been developed, including Redox, Hybrid and, Membraneless. The…

over 200 variations of the compound.

The percentage composition of carbon being 51.65, hydrogen being 7.24, nitrogen being 33.47, and oxygen being 7.64. The definition of solubility is the quantity of any given substance that can be dissolved in the other, or the maximum amount…

What is cancer and why is it bad? Cancer is caused by abnormalities (an abnormal condition or state) in the genetic material of cells (Rice). These abnormalities can be caused under the influence of something like chemicals, radiation, pollutants, and abnormalities that is presented in a person’s body from when they were born or the person may have inherited. Cancer is a general term used when typical cells grow and divide wildly, invading neighboring tissues, and consistently stretch to other…
