    Amino acids are known as the building blocks of all proteins that consists of 20 amino acids which are found in within proteins convey a vast array of chemical versatility. Amino acids are comprised of a carboxyl group and an amino group that attached to the same carbon atom which is the α carbon. They vary in size, structure, electric charge and solubility in water because of the variation in their side chains (R groups). Detection, quantification and identification of amino acids in any sample

  • Essay On Dangerous Hair Products

    762 Words  | 4 Pages

    Dangerous hair products In recent years, many people are choosing natural products for hair and skin care. The main reason for that is the fact these products are full of chemicals and harmful toxins that may have a negative impact on the health. Many researches and studies have shown that nutrition is very important, but it is not the only way how the toxins and chemicals can get into the bodies. Another option that is often completely disregarded, is by regularly using and applying certain products

    In both ‘Digging’ and ‘Follower’, Heaney creates a tone of respect and admiration for his father and grandfather that permeate all aspects of the poems. He portrays them as being strong, skilful and dedicated; this is achieved through the use of vivid descriptions, structure and careful placement of words with connotations. In ‘Follower’, Heaney portrays his father as skilled and knowledgeable. Throughout out the poem, Heaney uses specialized terms to describe his father’s job, such as ‘shafts’

  • Saponification Process Of Soap

    750 Words  | 3 Pages

    The saponification (a reaction in making soap) process is a base (usually NaOH or KOH) hydrolysis of triglycerides to make salt (soap) and glycerol. Alkalis such as Sodium carbonate and Sodium hydroxide are used to neutralize the fatty acid and convert it to a salt. The molecules crystallize differently depending on the base used. NaOH produces a harder bar while KOH is used more frequently for liquid soaps. In some cases, Lithium soaps are formed and produce much harder soaps. There are four

    obtained and chilled in an ice bath for three minutes. The ether was then added to the centrifuge using a pipette. In step four, it was observed that using a wooden stick helped dissolve the simple quicker. Once fully dissolved, one milliliter of 0.5 M sodium hydroxide was added in step four and it was observed that there were two layers. With water being denser, it was observed at the bottom later. In step five, the top layer was rinsed with the bottom layer ten times. In step seven, the aqueous phase

    actual yield is 0.38 grams. So if 0.38 is divided by 0.49 and multiplied by 100 then the percent yield for Zinc Sulfide would be 77.6%. When it comes to Sodium Chloride, the theoretical yield is 0.58 grams and the actual yield is 0.45 grams. So when 0.45 grams is divided by 0.58 grams and multiplied by 100, the percent yield would be 77.5% of Sodium chloride. The actual yield is directly taken from the mass of the products in the experiment while the theoretical yield is determined by using stoichiometric

    percent yield we reached was 130% yield which is clearly much more than the perfect 100% yield. Oddly, the yield was greater than 100%, meaning that we ended with more copper(II) oxide than should have been possible considering how much copper(II) sulfate we started the reaction with. We indeed did have an experimental yield of 0.850 g which is almost two hundredths of a gram larger than the theoretical yield of 0.6531 g. This would be considered rather unsuccessful as a result of the almost impossible

    The Citric Acid Cycle/ Kerbs Cycle/ TCA The Citric acid cycle is important as anaerobic glycolysis can only harvest a fraction of the energy from glucose. In the citric acid cycle there is aerobic respiration of pyruvate from step ten in glycolysis to C02 and H2O. This oxidation of pyruvate can greater a higher yield of ATP. The citric acid cycle occurs in the mitochondria where ten ATP is produced. The main purpose of the citric acid cycle is to harvest electrons from the citric acid cycle and

    salt makes contact with water, it seems to disappear. Although it may seem like magic, the salt is just dissolving. This is due to the bonds between the molecules being broken down. The most well known type of salt, NaCl, is just a combination of sodium and chlorine ions, which have a relatively weak bond strength. Conversely, the hydrogen and oxygen in water are bound together by covalent bonds. The positively charged end of the water molecule is attracted to the negative salt ion as well as the

    The goal of the experiment is to synthesize a bromohexane compound from 1-hexene and HBr(aq) under reflux conditions and use the silver nitrate and sodium iodide tests to determine if the product is a primary or secondary hydrocarbon. The heterogeneous reaction mixture contains 1-hexene, 48% HBr(aq), and tetrabutylammonium bromide and was heated to under reflux conditions. Heating under reflux means that the reaction mixture is heated at its boiling point so that the reaction can proceed at a faster

    Do you want to be put under the risk of the negative impacts your body can get from smoking or even secondhand smokinge? Smoking should not be allowed at parks and other public venues because it has health risks associated with it, it creates a dirty and unsafe environment and it is a bad influence. Smoking itself has many health risks, but for it to be allowed in public places imposes even bigger health risks to the public. The first reason smoking should not be allowed in public places such as
