酒精饮料在人体内的代谢及适宜饮量

Metabolism of Alcoholic Beverage in Human Body & Its Optimum Drink

被饮入人体的酒精经过肠道被吸收后由静脉输送至肝脏,酒精在肝脏被氧化为乙醛进而变为乙酸,乙酸除一部分在肝脏被利用外,大部分由肝脏输送到全身的各组织部位,最后被氧化分解为二氧化碳和水。酒精在人体内的主要代谢氧化路径有ADH和MEOS代谢径路两种。人体对于酒精的代谢能力因饮酒年龄、酒种、酒度、饮酒方式及饮酒者身体状况而异,成年人1 kg的体重在1 h内可以通过肝脏氧化处理掉100 mg纯酒精。(孙悟)

Alcohol in human body after intestinal absorption transferred into liver by veins and then oxidized into aldehyde and further into acetic acid. Most of acetic acid except a small part digested by liver was transferred in each part of human body and finally oxidized into CO2 and water. The metabolic pathway of alcohol in human body included ADH and MEOS. The metabolic activity of alcohol by human body was dependant on liquor types, alcohol content, drinking method, drinkers＇ age, and drinkers＇ health conditions. Adult could digest 100 mg pure alcohol by liver oxidation （per 1 kg weight body） within 1 h. （Tran. by YUE Yang）
