Question

b. Based on ionic stabilization effects, which molecule would have a lower pKs for the group listed? Explain in 2-3 sentences. 1 st digitmolecule molecule 2 0 glutamate carboxyglutamate7 a-amino pH group glutamate histidine alanine cysteine alanine auxin aspartate histidine threonine glutamine alanine cysteine a-amino 1a-carboxyl 91 -amino N-acetyl cysteine7thiol steinea-carboxy p-alanine carboxyl tryptophan succinate N-acetyl histidine - 1a-carboxvl 5 imidazole I a-carboxyl * N-acetyl modifications are produced when an acetic acid is linked to the a-amino group N-acetyl threonine 9 phenylalanine O-methyl phenylalanine 7 a-amino by an amide bond. : -methyl groups are produced by adding a methyl group (as an ester) to the a-carboxylic acid group. pamino acids have the amino group on the -carbon rather than the -carbon.

Explanation / Answer

Alanine. The solution with the highest pH will have a smaller pH value. There is a inversely proportionate relationship between pka and pH
