Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe. RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions.
I am afraid there is no specific answer to your question becuase there is not only one fell good chemical, there are 4:

Evidences from sleep research showed that human brain acquire memories during the day as we interact with our immediate environment,(synaptic consolidation) and when we sleep at night ,these memories are processed, stabilized and integrated into existing memory to form long term memory.(system consolidation).
The conversion and integration of the short term memory usually begins at average of 5-10 minutes, while stabilization into long term memory which is independent of the hippocampus takes average of over 1 hour after acquiring .
An adult, since they are fully grown, they possess the most unipotent cells.
