I finished exams (-_-), not talk about it as I have this much left, after much time here I leave a new actu.
This time, for the first time, I will place an article in Science (instead of absurd answers to tests ... ooooh ¬ ¬ U), so far I have not laid. Looking to future articles, I reported that when talking about science not put me to explain the mechanism of such a thing, or demasiaod technical data, but rather curiosities, anecdotes and interesting facts "and why is this so?" That has been finding the world and I too have found interesting. However, you must understand that you must first give a theoretical basis, but try to be as light pcterizados by the presence of a group
-OH (ie, an oxygen atom attached to one hydrogen atom), called hydroxyl .
is this group which, precisely, gives a series of special features. While many organic compounds are gases,
alcohols can be liquids at room temperature
, since with the OH group can form a kind of chain (called hydrogen bonds ), which stabilize the molecules. However, the strength of these connections is not as intense as, for example, water (which is liquid for the same reason), and that is why we have a low boiling
. All you have seen that if you put a little d Iand alcohol in hand, after a while it evaporates, and the heat of your body (about 37 ยบ C) is sufficient to pass from liquid to gas.
The alcohol in alcoholic beverages is called ethanol or ethyl alcohol, which has, in addition to the OH group, two carbons. CH3CH2OH
As you know, there are two types of alcoholic beverages: a) Fermented : Simply, they are subjected to fermentation and alcohol (ethanol, remember) that have found in small quantities. That is, we are talking about wine, cider or beer. Where does? The action of yeast (Saccharomyces cerevisiae as ), some microorganisms that are capableto convert glucose (a sugar component, also present in many foods) in ethanol.
b) Distilled : After fermentation, are carried stills, which separate the alcohol from other components using a technique based on the ethanol evaporates quickly, distillation. Therefore, have a high amount of ethanol, for what are essentially gin, vodka (yes, the organization of Detective Conan in full ¬ ¬ U) or various liquors. Known , let's see now what happens when we drink ethanol, for example, vodka and orange. After passing the small intestine, is absorbed by the blood and the liver (the major detoxifying the body), where an enzyme (a protein that is capableNo coenzyme A to form acetyl-CoA and sends it to the Krebs cycle, the formation of ketone bodies or form triglycerides, which subsequently act as reservoirs of fat.
Schematically, we have two reversible reactions chained like this: function
(or if the NAD + or NADH, worse was to put them)
[E] : The NAD / NADH, nicotinamide adenine dinucleotide, is an electron carrier to be reduced-is to gain electrons from NADH to form for ethanol can be oxidized to acetaldehyde-lose.
Oh yes, this has to do with what I said I'd try the input, patience
If U bi's name indicates that it is able to act on various types of alcohol), formaldehyde ( methanal ) yes that is highly toxic, and the body does not have a "formaldehyde dehydrogenase" to switch it off, as happened with acetaldehyde.
The increase of formaldehyde in the body causes a series of effects that do not produce ethanol and that obviously is not dealing with a drunk. These symptoms can make us suspect that this is a case of methanol poisoning :
- have previously drunk alcohol (not knowing of course that was adulterated)
- Blurred vision, blindness that can pass directly (very typical) Chas been (and loooong) xD I hope at least you liked, or like a little bit interesting (I'm content with that.) At least I currado figures ^ ^ U

science topic will be putting occasionally more, so go away from. In fact, I find them tageados by industry, so if clicking on a subject you can go to the various articles (or article only U) on the subject. You can leave me comments that you have some doubts about them, suggestions ("I've been too lax or too technical?), Inaccuracies, or just wear green ¬ ¬ U
soon! ;)
PS: I feel that with items so that LJ can not compete with those of fangirls praising the good guy
