PRACTICAL III: THE BEHAVIOUR OF AMINO ACIDS IN SOLUTION Abstract In this practical the acid-base behaviour of amino acids was assessed. Amino acids are amphoteric. They have the basic (amine) and the acidic (carboxylic) functional groups. These show the same type of equilibrium reactions that all weak acids and bases undergo‚ and the relative amount of each can be altered by adjusting the pH of the solution. For this practical glycine was used as a model to show this unique nature of

Complement is a system consisting of multiple proteins‚ available in plasma under the inactive form‚ mainly produced by the liver. Complement plays an important role in infection control. Involve in lysis activity‚ opsonic activity‚ join inflammation and fight infection Activation of the classical pathway needs the participation of the complement C1‚ C4‚ C2. Activation of the complement classical pathway usually begins with the formation of complex antigen-antibody dissolved either by binding of
