Amino acids are the building blocks of proteins. They band together in chains to form the stuff from which your life is born. Think of amino acids as Legos for your life. It’s a two-step process: Amino acids get together and form peptides or polypeptides. It is from these groupings that proteins are made. And there’s not just one kind of amino acid. A total of 20 different kinds of amino acids form proteins. The kinds of amino acids determine the shape of the proteins formed. Commonly recognized

Acid-Base Titration Background Information A titration is a controlled addition of one substance into another substance. In an acid-base titration‚ the experimenter will add a base of known concentration to an acid of unknown concentration (or vice-versa). The goal of the titration is usually to use the substance of known concentration to determine the concentration of the other substance. In order to run a titration‚ the following materials are needed: • A buret filled with the base (or acid) of

phosphoric acid‚ and 1mL of concentrated sulfuric acid was added to a 250 mL round bottom flask and mixed thoroughly with a magnetic stirrer. A simple distillation set up was installed with a 250mL round bottom flask‚ jack‚ stirrer‚ heating mantle‚ and variac. The solution was heated gently with a small heating mantle to distill the crude product while keeping the vapor temperature around 100C or less. The crude product was collected which contained water‚ 4-methylcyclohexene‚ and trace acid. D

bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure and its mechanism. After the addition of bromine to trans-cinnamic acid‚ the product was identified by its melting point and infrared spectrum resulting in erythro-2‚3-Dibromo-3-phenylpropanoic acid after comparing similar properties. Introduction In this lab‚ the bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure‚ and from there determine whether the

The one world factors I shall be looking at this from is environment and economic. By: www.leadbatteryuniversity.uk Batteries must always be drained before they enter the recycling process. They should only be drained to a purpose built effluent treatment plant so that the acid can be treated and neutralized. Next the batteries are broken in a hammer mill

Acidity’s effects on Fruit Browning Aim: To test whether the acidity of the surface area of an apple has an effect on the rate of enzymatic browning over 70 minutes. Hypothesis: the more acidic the surface area the longer it takes for the fruit to oxidise. Variables: Independent: acidity of surface area of the apple Dependent: the progression of melanin (brown pigment) after 70 minutes Controlled/fixed: time of day‚ knife used to cut fruit‚ portion of fruit‚ environment

ACID RAIN Acidified particulate matter in the atmosphere that is deposited by precipitation on to a surface‚ often eroding the surface away. This precipitation generally has a pH less than 5and some times much lower depending upon the concentration of acidic components. Acidic deposition principally by the pollutant gases such as sulphur dioxide (so2) and the nitrogen oxides cause acidic deposition. The burning of fossil fuels‚ such as coal‚ forms Sulphur dioxide. that contain high quantities of
