The R(-)-isomer of adrenaline is more potent. Its orientation allows its benzylic hydroyxl to form a hydrogen bond with Serine410 whereas this doesn't happen with S(-)-isomers of adrenaline.
Trans isomer packs more efficiently in the solid phase compared to cis isomer. This is because trans isomers have a linear structure that allows them to stack more closely together, leading to stronger intermolecular interactions and more efficient packing.
The trans-benzalacetophenone isomer is the major product in aldol condensation because it is more thermodynamically stable due to the extended conjugation in the molecule, leading to a more favorable resonance stabilization. The trans isomer also experiences less steric hindrance compared to the cis isomer, making it the preferred product.
Adrenaline can make ou more alert. Other than that, no.
You have to state more precisely WHERE the second methyl-group and the amine-group is situated before this Q. can be answered.
Sperm cells become potent around the age of seventeen and eighteen.
Yes
O-bromoacetanilide is removed from the p-isomer due to the differences in polarity and solubility between the isomers during purification processes, such as recrystallization or chromatography. The p-isomer, which has the bromo group in the para position, is generally more stable and less polar than the o-isomer, allowing for easier separation based on these physical properties. Additionally, the steric hindrance and electronic effects in the ortho position can lead to different reactivity, facilitating the removal of the o-isomer.
D and L are optical isomer of each other, or non superimposible mirror images. The convention uses Glyceraldhyde as the reference. In a fisher projection the OH of glyceraldehyde is on the right side ( more improtantly in the R configuration)in the D isomer and on the left side ( or the molecule is in the L configuration) in the L isomer. So for all other sugars it looks at the last chiral center for the molecule if the chiral center is R it is a D isomer if the last chiral center is in the S configuration it is an L isomer.
Yes, when a vampire feeds from a human they feel a rush of adrenaline as well as enhanced ecstasy. Vampires also feel adrenaline when they are fighting another vampire or equal or more strength as them.

The brain does not produce adrenaline, that is produced only by the adrenal glands.
There is an explosive greenhouse gas 20 times more potent than carbon dioxide.
