Q

How can the Henderson hasselbach equation be used to find the ratio of [A-]:[HA]

A

Substitute pH and pKa into the equation
pH -pka= log [A-]/[HA]
10^(pH-pKa)= [A-]/[HA]

Q

What does it mean for amino acids if the ratio of A- is greater than HA

A

This means there are less protons present so the carbonyl group of the amino acid would be unprotonated

Q

What does it mean for an amino acid if the ratio of BH+ is greater than B

A

Protonated form of base would be higher
This means that there is a high conc. Of protons present
Therefore amino group of tre amino acid would be protonated

Q

How can you predict the structure of an amino acid using the Henderson hasselbach equation

A

Find ratio of [A-] to [HA] and then the ratio of [B] to [BH+] using Henderson hasselbach
If A- >HA= low conc. Of protons =coo- group unprotonated
If B> BH+ = low conc. Of protons= NH2 group unprotonated and vice versa
