Glutamate is converted into α- ketoglutarate by the reaction sequence shown below. The structure of the imine intermediate is to be shown and mechanisms for both steps are to be proposed. Concept introduction: Transfer of a hydride ion from the glutamate to NAD+ followed by the deprotonation of the intermediate formed will yield the imine. The attack of water on the protonated imine and subsequent deprotonation yield a carbinolamine intermediate. The intermediate on further reaction breaks to yield a ketone and amine /ammonia as products. To show: The structure of the imine intermediate formed when glutamate is converted into α- ketoglutarate by the reaction sequence shown below and to propose mechanisms for both steps.

Question

1. This experiment is more about understanding the colligative properties of a solution rather than the determination of the molar mass of a solid. a. Define colligative properties. b. Which of the following solutes has the greatest effect on the colligative properties for a given mass of pure water? Explain. (i) 0.01 mol of CaCl2 (ii) 0.01 mol of KNO3 (iii) 0.01 mol of CO(NH2)2 (an electrolyte) (an electrolyte) (a nonelectrolyte)

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
