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 isomers
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
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.
spinach is the most potent source of vitamins
Optical isomers are those which have one or more asymmetric carbon atoms their optical activity means a tendency to rotate the plane of plane polarized light but some of such molecules have an internal symmetry as meso form of Tartaric acid , this is the optical isomer of Tartaric acid but is optically inactive.
