coagulation floated to the surface of solution. The curve of succinylated egg white did not change much. The –NH3+ of protein in egg white was replaced by COO- at pH8‚ so the protein was negative charged. The fastest coagulation of protein is at pI (isoelectric point). Because the pH of solution was at pI‚ the whole process is slow. The aim of this period of experiment is calculating the percentage of succinylation of the sample. Ninhydrin reacts with –NH2 to give a purple colour. There are three samples

1) Comment on the pros and cons of using CM-5 chips in SPR analysis (3 marks). CM-5 chips can provide a relatively high carboxylation of dextran matrix which develops high negative-charged surface that contribute to bind large amount of ligands. However‚ the high negative-charged surface may increase the chance of non-specific binding of other stronger positively charged molecules causing false positive signals. Covalent bound with the ligand through the EDC/NHS activation process

Title Freezing and Melting Point Objectives 1. To gain proficiency in constructing a graph and plotting data points. 2. To determine the freezing points of a compound from the graph of decreasing temperature versus time. 3. To determine the melting points of a known and unknown compound. Introduction Physical changes are the changes in the physical properties of a substance (Moore‚ Stanitski & Jurs‚ 2009). Freezing point is the fixed temperature at which a pure liquid converted into crystalline
