Phenylketonuria and of its properties. Phenylketonuria also known as PKU is a rare metabolic disorder caused by a deficiency of phenylalanine hydroxylase ‚ which is an enzyme that helps to convert phenylalanine‚ an amino acid that is found in foods‚ into tyrosine‚ an amino acid that creates melanin (Letcher‚ MA & Hunt‚ PhD‚ CGC‚ 2016). Phenylalanine is a vital necessity for the human body because it helps to construct proteins for the body and without phenylalanine hydroxylase to convert phenylalanine

from several hundred to several hundred million molecular weight units - and are made up of monomer units. There are four major classes of biological macromolecules: proteins‚ carbohydrates‚ lipids‚ and nucleic acids (Sheeler & Bianchi‚ 1980). Proteins are made up of polymers of amino acids. The shape and structure of a cell is defined by proteins (Alberts et al.‚ 1989). Carbohydrates are made up of polymers of simple sugars called monosaccharides.

polymerase reaches a special base sequence called termination signal‚ transcription is then over. This is called termination. The row of “guitars” represents the sequence in the tRNA anticodons. The tan balls on the bottom of the “guitars” represent the amino acids in the polypeptide chain. The multi-color piano keys represent the different bases that are in DNA and RNA molecules. What is different in the second strand than the first upper strand is that the second strand is mRNA which contains the base

expected melting point. After its temperature reached the plateau‚ the temperature increment was set at 1°C per minute‚ and the melting point range of 152°C-154°C was recorded. After standardizing the melting device‚ a small sample of unknown carboxylic acid was placed in a capillary tube‚ and an arbitrary plateau of 200°C was set. When the sample started to melt at 150°C‚ another capillary tube containing a small amount of unknown sample was placed in the melting device‚ and the plateau was set to 135°C

The Effects of Acid Rain on Plant Growth PURPOSE The purpose of this experiment was to determine to what degree acid rain affects the growth of certain plants. I became interested in this idea because I’m worried about our environmental conditions and it sounded very interesting to me. The information gained from this experiment may be used to as a warning to stop air pollution. HYPOTHESIS My hypothesis is that the plant watered with the acid solution will grow more slowly than plant’s

The proteins in groundnut are well balanced‚ except for slight deficiency in some of the essential amino acids. As it happens‚ these amino acids are‚ abundant in milk which can be combined with groundnut products for better results. For proper digestion‚ groundnut requires thorough mastication. Experiments made with the groundnut show that it is quite indigestible unless

DETERMINATION OF FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low‚ because of low sugar content and high fruit acid content‚ this makes the fruit taste sour. During the ripening process the fruit acids are degraded‚ the sugar content increases and
