Experiment 10 – Enzymes Enzymes are proteins that act as catalysts for biological reactions. Enzymes‚ like all catalysts‚ speed up reactions without being used up themselves. They do this by lowering the activation energy of a reaction. All biochemical reactions are catalyzed by enzymes. Since enzymes are proteins‚ they can be denatured in a variety of ways‚ so they are most active under mild conditions. Most enzymes have optimum activity at a neutral pH and at body temperature. Enzymes are

The tert-butyl group has been broadly used to protect functional groups in natural product synthesis such as amino acid‚ peptide and protein chemistry [1]. The tert-butoxycarbonyl (BOC) group is known as protecting group for amides in organic synthesis. The introduction of BOC group improves the solubility of organic precursors and their processability in organic synthesizes [2]. The methyl substituted pyridine derivatives were widely reported for their various biological activities such as anxiolytic

Academic integrity is the individual’s responsibility and personal choice‚ the educational institute can police‚ however‚ its up to each student to be honest with themselves and with each other‚ with everything they do in life. The student needs to commit to honesty‚ trust‚ fairness‚ respect‚ and responsibility during their academic and professional careers. When the student commits to these fundamentals and puts forth the necessary effort‚ they will be rewarded with a higher level of understanding

their interaction with the active site are categorised as either short/medium duration or irreversible (Rang & Dale‚ 2007). The study of cholinesterase hydrolysis and inhibitory actions demonstrate the key pharmacological principles of enzymatic catalysis and proteins as targets for drug action. Their importance is evident in a study conducted by Kumar et al (1989)‚ where significantly lower cerebrospinal fluid AChE activity in early onset patients of Alzheimer’s disease and an altered AChE/BChE ratio
