the alpha-imino acid is rapidly hydrolyzed to form an alpha-keto acid with the production of an ammonia molecule. This alpha-keto acid further undergoes decarboxylation reaction of Step (3) under a heated condition to form an aldehyde that has one less carbon atom than the original amino acid. A carbon dioxide molecule is produced here. These first three steps produce the reduced ninhydrin and ammonia that are required for the production of color in the last two Steps (4) and (5). The overall reaction

sodium chloride (common table salt) in water is called brine. A sterilized specific concentration (0.15 molar) of sodium chloride in water is called saline. A solution of carbon dioxide in water is called seltzer‚ and a solution of ammonia gas in water is called ammonia water. A solution is said to be dilute if there is less of the solute. The process of adding more solvent to a solution or removing some of the solute is called diluting. A solution is said to be concentrated if it has more solute

chloride excreted in the urine is about 10 to 15g each day. As you might expect‚ the exact amount of these ions in the urine varies with the amount in the diet. The ammonium ion (NH4+) is produced by the deamination of amino acids in the kidney. Ammonia is an important compound in the regulation of pH because it accepts a proton to form the ammonium ion‚ which can then be excreted in the urine. This process gives our bodies a way to remove protons from the blood. High levels of the ammonium

mixture for about 10 mins. If needed‚ add more water to maintain constant volume of solution while boiling. Test the vapour at the neck of the flask with a moist strip of red litmus paper. If ammonia is still present the paper will turn blue and heating should continue until the litmus paper no longer detects ammonia. Cool the flask once completed. 7) Rinse and fill a burette with standard hydrochloric

These can be natural‚ synthetic‚ recycled wastes or a range of biological products including microbial inoculants. Except for microbial inoculants (biofertilizers)‚ all of these contain one‚ two or several plant nutrients in readily or potentially available forms. A certain supply of mineral and organic nutrient sources is present in soils‚ but
