Amino acids are metabolized by a transamination reaction in which the amino group of the amino acid changes places with the keto group of an a-keto acid; the amino acid and a new a-keto acid. Draw the products of the transamination reaction between threonine and 2-oxopentanedioate. • You do not have to consider stereochemistry. • Use the charge tools to adjust the charges of the amine and carboxyl groups to the form in which they would be found at physiological pH. • Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. • Separate multiple products using the + sign from the drop-down menu. ? √n [ Ⓡ ChemDoodle

Black powder (see introduction) was the propellant used in rifles and pistols during the 1860’s.  Would it have been possible to use diphenylamine to detect gunshot residue on John Wilkes Booth after the assignation of President Lincoln?  Why or Why not?

What is the product in the reaction of 1,3-Diaminopropane, Nickel(II) Acetate Tetrahydrate and Pyrrole-2-carboxaldehyde?

Suppose you were given the structural formula of compound B but only the molecular formulas for compound A and the starting bicyclic amine. Given this information, is it possible, working backward, to arrive at an unambiguous structural formula for compound A? for the bicyclic amine?

propanoic acid + methanol (in concentrated sulfuric acid)

In the preparation of p-Nitroaniline what is the name of the type of reaction you are performing here? What functional group did you start with and what functional group did you make at the end?

Gabapentin, an anticonvulsant used in the treatment of epilepsy, is structurally related to the neurotransmitter 4-aminobutanoic acid (GABA). -NH2 -NH, B -СООН COOH Gabapentin 4-Aminobutanoic acid (y-Aminobutyric acid, GABA) Gabapentin was designed specifically to be more lipophilic than GABA and therefore more likely to cross the blood-brain barrier, the lipidlike protective membrane that sur- rounds the capillary system in the brain and prevents hydrophilic (water-loving) com- pounds from entering the brain by passive diffusion. Given the following retrosynthetic analysis, propose a synthesis for gabapentin. -NH, -NH2 CN COOH -COOEt COOEt Gabapentin COOEt COOE. O + COOEt COOEt Cyclohexanone Diethyl malonate

A student decided to run the esterification reaction between p-toluic acid (p-methylbenzoic) and ethanol but found that the stockroom had only just enough ethanol left to react with her carboxylic acid, that is, a stoichiometric amount of alcohol. Furthermore, the only concentrated acid the stockroom had left was hydrochloric acid (a non-dehydrating acid ). What other method (s) could she use to drive the esterification reaction to completion ?
