    Title Biochemical Analysis of Blood Abstract Introduction After blood is collected from a patient it is analysed to check the fragments present and the fluid which will either be plasma or serum. After plasma is separated from blood it recollects the fibrinogen which in turn helps in clotting however serum is the portion of blood which remains after the fibrinogen is removed. Serum contains approximately 6-8% of the proteins which make up blood however plasma creates up to 55% of blood

    Aim: To verify the buffering capacity of a phosphate solution using a pH meter and construct a titration curve of an amino acid to determine the pka values of its ionisable groups to identitfy an unknown amino acid. Method: The ratio of [HPO42-] to [H2PO4-] required to produce buffer solutions at pH values 5.9‚ 6.9 and 7.9 were calculated. 0.1M of H2PO4- and 0.1M HPO42- were used to mix appropriate volumes to 25mL of each of the buffer solutions. The calibrated pH meter was used to measure
