In modern society, with the improvement of living standards and increased socializing, many people will often drink, easy to get drunk after drinking face red, many people think it is drinking face red is caused by alcohol, but in fact, it is caused by acetaldehyde. Acetaldehyde has the function of making capillaries dilate, and the expansion of capillaries in the face is the reason for the blushing. So people who drink and blush means that they can quickly convert ethanol into acetaldehyde, which means that there they have efficient ethanol dehydrogenase. But there is another type of acetaldehyde dehydrogenase inside the human liver. People who drink and blush have only the former enzyme but not the latter, so the body rapidly accumulates acetaldehyde and is slow to metabolize it, so they stay red for a long time. However, as we all have experienced, when the red color gradually goes away after 1-2 hours, this is because the P450 enzyme system in the liver slowly converts acetaldehyde into acetic acid, which then enters the TCA cycle and is metabolized. The reason why people appear intoxicated is because the concentration of acetaldehyde in the body is too high and the symptoms of mild acetaldehyde intoxication appear. Simply increasing ethanol dehydrogenase will not increase the amount of alcohol consumed. The presence or absence of these two enzymes is related to the individual’s constitution. If you have these two enzymes, you can gradually increase the amount of alcohol you drink to stimulate your body to secrete higher concentrations of these two enzymes when you drink, and you will be able to increase the amount of alcohol you drink. If you lack these two enzymes, you can only rely on external supplementation, external supplementation can only improve the amount of alcohol for a short period of time, no matter how to exercise themselves can not improve the amount of alcohol. Now there are some health supplements on the market to solve the problem of alcohol and protect the liver, in fact, the main ingredients inside him are amino acids and these two enzymes. The actual health care products can increase the amount of alcohol, such health care products can temporarily increase the concentration of these two enzymes in your body, can increase the amount of alcohol in a short period of time.
