Vitamins and minerals are both essential nutrients that are needed by the body. Different from the macronutrients, they are said to be micronutrients by meaning that they are needed only in small amounts. Nevertheless, we should not forget about their essentiality and their importance in our daily diet1. There are two types of vitamins, fat-soluble and water-soluble. Fat-soluble vitamins include vitamin A, vitamin D, vitamin E and vitamin K. They are found in fatty foods and animal products like…

Blood is composed of two elements which are plasma and formed elements. Blood plasma is the main component of blood occupying on average about 55% of the total blood volume. The main component of plasma is water making up to 92% of the volume of the plasma. Other components of the plasma are substances like proteins, carbohydrates, amino acids, lipids, vitamins, electrolytes, hormones cellular waste products and dissolved gasses. The formed elements part of the blood are composed of the cellular…

One of the most expensive organs in the human body is the brain. The physiological task of the brain includes receiving information from the rest of the body, deducing that information, and then guiding the body’s response to it. The brain also helps perform vital processes such as maintaining blood pressure, releasing hormones, and respiratory functions. For a while, many scientists thought that all mammalian brains (including the human brain) were made in the same way. Therefore, it is fair to…

molecular weight (number of base pairs) of each fragment. The agarose gels allowing separation of framents whose size is between 0.5 and 20 Kb. Ten microliters of amplification product are added 5 microliters of hare buffer (0.25% bromophenol blue, 30% glycerol, 40% sucrose); the mixture is then deposited in the wells. A negative witness is treated in the same conditions as the different samples: the 5 microliters of extracts are then replaced by 5 microliters of water purified in order to…

and adults. Babies consume this at their early stage during breastfeeding, while the rest ingest it by eating fruits. However, pure Lauric acid can not be ingested since it could cause irritation, but there are no gastrointestinal problems when is glycerol is chemically bonded. (Davidson, 2003) According to research, it has many health benefits due to its antimicrobial properties, but it 's not yet confirmed. The chemical formula for Lauric acid is C12H24O2 and has a molar mass of 200.32. Its…

structure adhered to cell which is made of glycocalyx polysaccharide, glycopeptides etc.,. Capsules are usually polysaccharide in nature, may be homo/mono polymer of (glucans, dextrans, levans) or hetero/polymer of (hexose and pentose sugars plus ribitol/glycerol/other sugar alcohols) and capsule can also be composed of phosphoesterases. Capsule is also made of repeating oligonucleotide of more than one monomer. Many exopolysaccharides are acidic in nature due to heavy carbonyl groups either…

Chapter1. The development of biodiesel The name biodiesel refers to the fuel that comes from biological sources and is mainly to be applied in diesel engines. The National Biodiesel Board (NBB) defines biodiesel as “a domestic, renewable fuel for diesel engines derived from nature oils”. As a matter of fact, biodiesel is so called not only because of biologically derivation as waste raw materials are also commonly used in production (Sunggyu Lee 2012). Compared with massive GHG emissions of CO2,…

The FTIR spectra of four phosphazenium salts and P5+ are shown in Figure S1. Four phosphazenium salts have characteristic absorptions at 2850 and 2930 cm-1, belonging to the stretching vibration of -CH2- and -CH-, respectively, and this peak in the P5+ represents the absorption of –CH3. All the five compounds exhibit absorption at 960, 1230, and 1442 cm-1 corresponding to the stretching vibrations of P–N. In the FTIR spectrum of Cy4P1+BF4-, the peaks at 1633 and 3432 cm-1 belong to water because…

Since the beginning of time, Staphylococcus, also known as staph infection, has (Khan, 2017), but there was not an official discovery of what it was until much later. In the year of 1880, a surgeon discovered the bacterial infection in a patient after a surgery (Mandal, 2012). A staph infection is an infection caused by a group of Staphylococcus bacteria that can cause many different conditions and diseases. Believe it or not, the Staphylococcus bacteria is found in the normal flora of the body…

The results of the experiment showed a significant change in plasma glucose and serum cortisol concentrations of the sheep that were administered insulin which validates the hypothesis of the experiment. Glucose does not readily penetrate cell membranes as cell membranes are composed of phospholipids and glucose is hydrophilic and lipophobic due to the hydroxyl groups (Klein, 2013). Insulin, the major hormone that controls plasma glucose concentrations, increases the permeability of the liver,…
