The Hans relieve alcoholic intoxication to depend on " Du Kang's gene "
It is reported ' Reporter Hu DeRong) Modern anthropology key laboratory Li Hui seminar of Ministry of Education of Fudan University finishes a research recently, very strong detoxication have found about 70% of the the Han nationality has one kind in the human body " Du Kang's gene " --A kind of variant of the ethanol dehydrogenase gene. Their theses of research are issued on the newest British " newspaper in human heredity academic year ". " Dukang's gene " The scientific name is the seventh inferior clan gene (ADH-1-B) of ethanol dehydrogenase ,Its main function is to resolve the alcohol that the human body is taken in into acetic aldehyde, acetic aldehyde is further resolved under the function of second aldehyde dehydrogenase into the acid of second, and second acid numerous supersession react substrate that need in the human body, this finish the intersection of human body and the intersection of detoxication and course in alcohol. Scientific research personnel such as Li Hui,etc., through carrying on the finding to analyzing of DNA to the mummy, the crowd of the Han nationality is in evolution, some people because alcoholism is dead, other people's gene has morphed, adapt to this kind of toxin gradually, happen in summer, Shang and Zhou period it is China correspondingly in this period. The Chinese had development advancing by leaps and bounds in agricultural production in this period, the grain have more than needed, corner, make wine, drink and propagate its belief on a large scale too in a large amount. Du Kang in the legend, the famous " wine celestial being " in last years of Xia dynasty . Because this last forming times with " Du Kang makes wine " The time of this historical story is identical, so called " Dukang's gene " by the expert . Why have a lot of people drink too in Europe, European find ethanol dehydrogenase the seventh inferior clan gene in the colony? Li Hui explains, Europe is until Middle Ages agriculture is undeveloped, there is little grain that is used in making wine, so, alcohol is short to the choice time of European crowd's gene, function is very weak. This has explained why a lot of ethnic minorities specializing in moving about in search of pasture of our country do not have this kind of gene too. Since crowds of the Han nationality generally have the seventh inferior clan gene of ethanol dehydrogenase which decomposes alcohol with very strong ability, then can the Hans follow one's bent while drinking? Li Hui's answer is denied. He says, though there is the seventh inferior clan gene of ethanol dehydrogenase in most human body of the Han nationality, but this kind of gene can only resolve alcohol into acetic aldehyde, acetic aldehyde is still toxicant to the human body, it is the amazing reason because of acetic aldehyde that a lot of people blush after drinking. If want to resolve acetic aldehyde into the nonpoisonous second acid completely, need second aldehyde dehydrogenase, but it's a pity this kind of enzyme is that most the Hans are scarce. So, for the health, or should try hard to drink few.
