4 important questions on Which neurotransmitters there are, how these are categorized and their main functinos

What are the two main categories of neurotransmitters?

The two main categories of neurotransmitters are small-molecule transmitters and neuroactive peptides

Name 4/5 subgroups of small-molecule neurotransmitters

4/5 subgroups of small-molecule neurotransmitters are
-catecholamines (dopamine, (nor)epinephrine)
-indolamines (serotonin, histamine, melatonin)
-amino acids (aspartate, y-Aminobutyritic acid, glutamate, glycine)
-other (acetylcholine, adenosine, ATP)
-endocannabinoids  ( 2-DHG/AEA/2-AG<-, carbon monoxide, nitric oxide)

Name the precursors of DA, NE, E, 5-HT, His/H, GABA, Glu (E), Ach, DHA/AA<-

DA- tyrosine
NE-trysoine
E-tyrosine
5-HT  -tryptophan
His/H - histidine
GABA-glutamine
Glu (E)- glutamine
ACh- choline
DHA/AA < - alfa linoleic acid
