Document Summary

If someone takes a dose of meth every day, they can stay stable and avoid overdose. Lipids: structure & synthesis: lipids, naturally occurring molecules. Includes: fats, waxes, hydrophobic, function, energy storage. In emergency times: structural component of cell membrane, signalling pathways, synthesis pathway, remains unclear for many lipids that also serve as neurotransmitters/modulators. Nucleosides: subunit of nucleic acid, nucleic acid, heredity controlling component of cells, e. g. Influences activity of neurons throughout brain: sleep, arousal, appetite, temperature, working memory, hallucinations, mood, higher levels of serotonin higher levels of manic/happy. Serotonin synthesis: synthesised in the raphe nucleus. In cell body: transported to synapses where it is stored, when neuron fires, the 5-ht is released from synapse, synthesis, starts as tryptophan, amino acid found in food, e. g. chocolate, raw chicken, cheese. Is synthesised to form serotonin (5-ht: by enzyme tryptophan hydroxylase (tph, broken down by enzyme monoamine oxidase (mao)
