The "chemical that breaks down alcohol" is alcohol dehydrogenase. I don't know that it can ever be detected in urine, but if it can, it's perfectly normal for it to be there since it's a protein produced naturally by the human body.
The usual "urine test" for alcohol looks for the marker compound ethyl glucuronide, which will be detectable for several days after consumption of alcohol ... it's an extremely sensitive test. Some reports I've seen indicate that it's readily detectable for three days after the last consumption of alcohol (a Swedish study found that 7 g of ethanol ... less than the amount in a single 8-ounce glass of 3.2% beer ... was detectable 6 hours after consumption; if you've drunk enough to be buzzed, it's going to be detectable for at least 3 days).
that depends on what it was you were drinking how and long you took to drink it but if it was one beer and you didn't stretch it out then about an hour
It depends on the amount in the bloodstream!
around 24 hours to 2 days
Sperm and urine are not in the same place.
Depends on how hard you push
Y sperm can stay in womb for 36 hours after which it dies
yes it can. it can stay on your clothes for up to 12 to 72 hours before it comes off
Hmm, I think it's used to wash the DNA from the substance used for extracting the DNA, such as Isopropanol, CLS, NLS, PPS which are used in the process of extraction to the process to precipitate the DNA (using isopropanol). DNA is insoluable in alcohol. Actually the real reason for using alcohol in a DNA extraction is to "precipitate" (NOT RAIN) the DNA, as you may have realized when you did the experiment , the Alcohol step is the last step that brings the DNA to the surface. Finally alcohol can be added so that the DNA can be seen, but first it is crucial to know why the addition of alcohol is such an important step. This step is closely related to a process called precipitation, which is " the process of separating a substance from a solution as a solid" (answers.com, precipitation). Precipitation separates the DNA so that it can no longer remain dissolved and so that it can be seen. DNA is less dense than water and alcohol , so the DNA rises to the alcohol layer. Also the DNA is soluble in water and insoluble in alcohol, so when it is just in the mixture it is quite invisible but once the alcohol is added it condensates by precipitation to the point where it is very visible.
Alcohol can stay in your system for up to 80 hours in a regular urine test.
80 hours after the alcohol has been metabolized by the body.
about 48 hours. just drink plenty of water
They stay in your urine for as long as they stay in your body. It's different for each substance you put in your body.
No
No. Alcohol will stay in your system for around 8 hours, regardless of what you try to do. After this point, the hangover will usually kick in, which varies from person to person.
Coricidin hbp can stay between four to six hours in your urine
Maybe. The test is extremely sensitive. 96 Hours is safer. In other words, don't drink and stay away from anything that contains alcohol.
36 hours?
about 72 hours
Alcohol is gone in a short time, but its metabolites can linger for about five days. Most urine tests are for metabolites.
Generally, 72 hours.
