that the toothbrush can scrub them away. Detergents have cleaning agents called surfactants. Surfactants are in toothpastes to loosen stuck-on food and plaque so your toothbrush can get rid of it better. The most common surfactant is sodium lauryl sulphate. Fluoride fights tooth decay by strengthening the enamel. It does this by a chemical reaction called remineralisation. Fluoride is most frequently in the form of sodium fluoride‚ sodium monofluorophosphate‚ or stannous fluoride. Desensitizers help

are essential to protein structure. Determining the number of thiol groups in a protein is important in determining the tertiary structure of the protein. The ovalbumin is the experiment was purified from egg white using centrifugation and ammonium sulphate precipitation and then the thiol groups identified using DTNB and spectroscopy. The ovalbumin was found to have one thiol group; from this we were also to infer that DNTB alkylates thiolgroups; whereas SDS keeps proteins denatured. Introduction

Depletion of the Ozone Layer * Function and location of the Ozone Layer The ozone layer is a portion of earth’s atmosphere that contains high levels of ozone. Ozone (O3) is a triatomic molecule consisting of three oxygen atoms. It is an allotrope of oxygen. Ozone is formed when oxygen molecules after absorbing ultra violet photon then converts a single O2 into two atomic oxygen radicals. The atomic radicals then combine with separate O2 molecules to create two O3 molecules. The main function

1.0 Title Determination of Protein Content Using Kjedahl and Titration 2.0 Introduction Proteins are polymers. They are the source of dietary amino acids and are used for growth and maintenance of living systems. They are costlier sources of energy compared to carbohydrates and fats and hence the human body utilizes proteins mainly for biosynthesis rather than as an energy source‚ though the energy yield is 5 kcal/g of protein. Twenty different types of amino acids occur naturally in proteins

Smoking is a practice in which a substance‚ most commonly tobacco‚ is burned and the smoke is tasted or inhaled. This is primarily practised as a route of administration forrecreational drug use‚ as combustion releases the active substances in drugs such as nicotineand makes them available for absorption through the lungs. It can also be done as a part of rituals‚ to induce trances and spiritual enlightenment. Smoking is one of the most common forms of recreational drug use. Tobacco smoking is today

Solution A was prepared by transferring the calculated amount of malonic acid to a volumetric flask with a small amount of distilled water. Then the calculated amount of manganese sulphate solution was pipeted to the same volumetric flask along with distilled water to the mark. Solution A was then transferred to a labelled beaker. Solution B was prepared by collecting 30mL of sulfuric acid and the calculated amount of potassium iodate
