虽然消化与吸收是分别进行的,但把它分别进行比较、测定是困难的。Lundh的试验食等是良好的例子。但在理论上消化与吸收的机制是不同的。随着对消化吸收的生化学结构的了解,人们知道仍然不能把消化与吸收两者断然分开,像双糖类,其分解酶隐藏在刷状缘的微绒毛膜中,双糖类水解成单糖类是在膜上膜内或膜孔中进行;同样蛋白在水解成三肽、二肽等各种氨 Although digestion and absorption are carried out separately, but to compare them separately, the determination is difficult. Lundh’s test diet is a good example. But in theory digestion and absorption mechanism is different. With the understanding of the biochemical structure of digestion and absorption, people still do not know that digestion and absorption can not be categorically separated. Like disaccharides, their enzymes are hidden in the brush edge microvilli and disaccharides are hydrolyzed into single Carbohydrates in the membrane membrane or membrane hole in the same protein hydrolysis in the tripeptide, dipeptide and other ammonia
