The mechanism of each step involved in the biosynthesis of leucine from α-ketoisovaleate is to be given. Concept introduction: The steps involved in the biosynthesis given are i)The nucleophilic addition of –CH 2 CO CoA to the carbonyl carbon ii) Hydrolysis of the intermediate iii) Elimination of water iv) Conjugate addition of water v) Oxidation by NAD + vi) Decarboxylation of the β-keto ester vii) Nucleophilic attack of ammonia, loss of water and reduction To give: The mechanism of each step involved in the biosynthesis of leucine from α-ketoisovaleate.

Question

need help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).
