There are an estimated 200-300,000 different gene products.  Most of those are changed in some way by secondary modification, so figure about 500,000 to a million just for the types of protein alone.  In addition, there are thousands of lipid and carbohydrate products, as well as individual amino acids, bases, ions, etc.  Well over a million different kinds of chemicals, if you include large organic macromolecules such as proteins.

This is definitely a myth.  We use all of our brain.  The origin of this myth is that only 10% of our brain is made up of actual neurons in the strictest sense.  That means that only 10% of the cells in our brain are the kind that transmit signals and make us think.  The other 90% are called glia.  These cells provide the structural support and nutrients for the neurons, as well as clear away their waste and excess neurotransmitters.  These cells are "used" just as much as the other 10% though.

When you took chemistry you were balancing an equation for baking soda and vinegar, or Iron and Oxygen.\n\nWhat's the equation for happiness, discipline or satisfaction?\n\nWe still don't know what all the chemicals ARE in the brain.\n\nThen we have to figure out what each chemical DOES.\nThen we have to figure out the equation for depression.\nThen we have to figure out how to change the balance of the chemicals.\nThen we have to figure out how changing the balance of one chemical upsets the balance of all the other chemicals.\nThen we have to figure out how to re-balance all the chemicals the drug put out of balance.\n\nAnd it all has to be done without any side effects on the rest of your body.

Rote memorization, with flashcards possibly, is the only way I can think of. Like the other poster said, look for carbonyls, alcohols, alkenes, and amino peaks (a weak, wide peak at about ... 3200 or so)

atom, molecule, cell, tissue, organ, organ system, and organism\n\nThe rest is a grand surprise that only the elite few can figure out.\n\nDon't hurt yourself with the pages of your Bio book.

If this is a plant, there will be thousands of chemicals present.  Of course water and celluose will be #1 and #2.

There was actually a very interesting article about the chemistry of love in "National Geographic" magazine a few months back. You should google their website and see if they have any info about it there.\n\nOne interesting note that I recall from the article: the chemical profile of the brains of people who are in love is very much like that of a bipolar person. In other words, love is a psychological disorder.\n\nScary, ain't it?

There are 4 primary dopaminergic pathways in the brain.\n\n1.  Mesocortical pathway: http://grad.uchc.edu/phdfaculty/images/antic/antic1.jpg  \n\n2.  Mesolimbic pathway:\nhttp://www.atforum.com/SiteRoot/images/GIFS/pg8.gif  or\nhttp://www.chemsoc.org/exemplarchem/entries/2004/nottingham_chong/steph/Scan10001.JPG or\nhttp://www2.alasbimnjournal.cl/AlasbimnImages/aj21-gardner-fig01a.jpg or\nhttp://homepage.psy.utexas.edu/homepage/class/Psy301/Salinas/sec2/Brain/30.GIF\n\n3.

Tuberoinfundibular pathway \n\nhttp://www2.alasbimnjournal.cl/AlasbimnImages/aj21-gardner-fig01a.jpg  in this figure, "The tuberoinfundibular tract originate from cells in the arcuate nucleus projecting to the median eminence.".  \n\nGood luck with whatever you need these for

That'd be Astatine, there's about 25g of naturally occurring Astatine on the planet only.

Try asking the question again? I don't think we have enough info. 30g of what substance? Plus the rest is just confusing.

It involves the hypothalamus, the pituitary, the thyroid, and thyroid hormones (T3/T4). You can do the rest, its pretty simple :)

100%  That 10% saying is bogus.  All of the brain is being used for something, whether it's memory, moving muscles, regulating heartbeat etc.  There is a smaller portion of it used for consciousness.
