Abstract

Disorders of dietary sugar assimilation occur more often among native people of the Arctic then in temperate climate inhabitants. It is hypothesized that the limited variety of natural exogenous sugars in the Arctic, and their low content in the traditional diets of native northerners in accordance with a "protein-lipid" type of metabolism weakened selection, favoring diversity of disaccharidase enzymes.

北极种群双糖酶的活性:进化方面的北极种群双糖酶。
饮食中糖的同化紊乱在北极的土著居民中比在温带气候的居民中更常见。据推测,北极地区天然外源性糖的种类有限,而且它们在当地北方人的传统饮食中含量低,符合“蛋白质-脂质”代谢类型,这削弱了选择,有利于双糖酶的多样性。
