Question
Chapter 1, Problem 66TQ
Summary Introduction
To review:
The order of reactivity in nucleophilic substitution reactions: phosphate>thiols>esters>amides, based on the pKa values. pKa values are given as: phosphoric acid- 1×10-3, hydrogen sulfide- 1×10-7, alcohols- 1×10-17 and ammonia- 1×10-36 .
Introduction:
pKa is an acid dissociation constant; it gives a quantitative measure of an acid’s strength in a solution. It shows the tendency of an acid to be able to lose a proton. The more positive the value of pKa, the smaller is the extent of dissociation.

Can koch's postulates of disease causation be applied to non-microorganism disease pathogens (such as molecules)?
Here is my literature Beta Carotene HPLC analysis graph.
Can you help me explain what each peak is at each retention time?
Thank You :D
I have a literature B-Carotene HPLC graph in which showcases a retention time of roughly 23.6 and 25.1.
Please help me compare my two different Anti-Oxidant Juice graphs. (Attached)
The juices provided are: V8 Carrot Ginger Blend and V8 Original Blend
Noticing the HPLC graphs I saw no peaks for the Original Blend for B-Carotene.
However the Carrot Ginger Blend showed similar peaks --> Why is this reason?
Please explain in terms of Retention time and Area (Under Curve).
Thank You!
