The word "blood thinner' is a pretty generic term, but in the medical field we usually designate it as an "anti-coagulant" such as heparin and coumadin, which exert their mechanism of action on the coagulation cascade. These are used for in general preventing clots induced from coagulation factors, and people who take these meds are monitored weekly for their PT/INR (coumadin) and PTT (heparin) so that their blood doesn't get too thin. These patients also have a risk of having long bleeding times because of the meds and thus if let's say they have a history of GI bleed, we would not give them these because they could bleed to death. Aspirin on the other hand works on inhibiting platelet aggregation and is used for preventing thrombus-induced heart attacks (most heart attacks are caused by platelets coming together to form a clot after a plaque ruptures). I guess you could consider that a blood thinner but so I like to regard it as an "anti-platelet". You may be familiar with Plavix (clopidogrel) which does the same thing but has a different mechanism of action. Anyway, to answer your question to the best of my ability, there are no anti coagulants that are OTC, since they are potentially dangerous drugs. In regard to anti platelets, the only one I know is OTC is aspirin.

I remember when I was trying to understand Latex but couldn't get it (I'm kinda slow). And I still can't get it. I'm so proud

Collidine is just a type of pyridine with 2,4,6 methyl substituents. Why not use the main organic synthesis of pyridine? They have a process outlined in wikipedia. http://en.wikipedia.org/wiki/Pyridine

No, herman is right. When the people looked at the structure of benzene, they found that all the bonds were of equal length. This was due to resonance. So basically, the electrons are shared between all bonds, not just three bonds as you generally see it. Drawing benzene as 3 double bonds and 3 single bonds isn't a real accurate description because according to Kekule's rule, the double bonds actually resonate. So for benzene you actually have a blend of two possible resonance structures (if you move the double bonds around once you get the other resonance structure). You might notice that the probably best way to represent benzene is the hexagon with the circle in it, to represent the resonance. I think you get the gist. And 1,3,5-cyclohexatriene doesn't exist. It was a structure initially proposed by Kekule and other scientists for benzene, but was later disproven because they found that all the bond lengths were the same and thus resonance was born.

Monkeys are stupid!!!!!! lol jk carbon steel is now used i think for most ninjitsu weapons thanks ecoli for the info

That's the overall reaction. Now to balance it you only have to use common chemistry balancing knowledge

I remember a few years ago when i joined this site I debated with a girl named AzurePheonix about Iraq in the philosophy and debates section (it was later thrown into the archives) but I don't see her anymore. Anyone know what happened to her? I have been on hiatus so I might be missing out on things.

Just wondering what the mechanism is for forming tetralin from benzene and tetrahydrofuran using sulfuric acid. I know the aicd breaks the tetrahydrofuran ring by protonation but what happens from there?

I have an unknown that gives a positive 2,4-DNP test, a positive Tollens test, however, the chromic acid test is negative. What could possibly yield those results. I ran the tests 3 times and got the same result. Maybe contamination? Im suspecting maybe I did the chromic acid test wrong or something, because the other 2 tests point towards an aldehyde.

Can a sugar acetonide only form with 1,2 cis-vicinyl hydroxy groups? Is it possible to form bridges between 1, 3 hydroxy groups or 1, 2 trans hydroxy groups when reacting a sugar with acetone to create an acetonide?

also in addition to realtive stabilities you have to look at possibilities of R,s configurations, enantiomers, and meso compounds

ahhhh good now i see thnx a lot bud! \m/

:confused: Hi guys I dunno if yall remember me but I took a good long break from SFN but I'm back cuz I love science (lol) Anyway I also need your help. Um it would be helpful if someone explains how chiral center is a type of stereocenter. I know a stereocenter is an atom that when you interchange two groups it produces a stereoisomer but how does a chiral center fit that description?? My text does a bad job of explaining

well i only know that oxidation of hydrocarbons yields carbon dioxide and water...

I am here to announce his death recently...i wonder if he has done any achievements to benefit the scientific community? Any input anyone?

personally i like facebook

AHEm. My favorite of all is Nitric oxide. I personally did research on this gas, so i like it best booya. Oh yea. morphine too

I believe Formaldehyde poses carcinogenic threats as well

oh and by the way, Lysis does not only mean the explosion of cells; it could also mean the dissolution of cells.

The major difference is the word that comes before it. Cytolysis means when in a cell bursts due to hypotonic environments. This is where we usually use the term "lysis". however, the opposite, which is called plasmolysis, occurs in plant cells when water moves rapidly out of the central vacuole due to a hypertonic environment. i am not sure if animal cells can experience plasmolysis in their true environments, but i know for sure that plasmolysis is attributed mostly to plants. i hope that answers your question.

i accidently kicked a can on the street into the sewer drains, not knowing that it had a homeless woman's money in it

I was shopping at the mall underneath the WTC for my birthday (o btw yesterday was my birthday ) yea i dunt wanna talk about it

Australia. Ive always wanted to see Koalas and the jungles there. Hiking is one of the my most anticipated activities, and i would like to go on a trip thorugh the australian jungles

Killing stingrays to "avenge' Steve irwin's daeth is not gonna set things right. The stingray that killed him may have done it in self-deefense. this still doesnt mean you take out anger against innocent species that havent done anything.
