This results in a disproportionate amount of foremilk – and since foremilk is high in lactose, he may become gassy and spit up as a result of too much lactose being emptied into his bowel.

因为前奶中富含乳糖，宝宝可能由于肠道内太多的乳糖而胀气，还可能会呕吐。而正因为宝宝所吃的富含脂肪的后奶不够，他的肚子很快就会饿了，于是他很快就又想吃奶啦。

Fucose composed of 40% the total carbohydrate with lesser but approximately equal amount of galactose, glucosamine, and galactosamine present.

对糖萼的糖化学组份分析表明糖萼是由40％的岩藻及大致等量的半乳糖，氨基葡萄糖和氨基半乳糖组成。

PL2-1 was found to be a galactan, whose main chain consists of (1→4)-linked galactose, and a few of 1→3, 6 linkage, as branched points, arranged in the interval 1→4 linkage between. Some of them were located at the end of unreduced group.

实验结果表明，PL2-1为半乳聚糖，主链和侧链主要以1→4位键合，少量以1→3，6位键合的半乳糖构成主链分枝点，间隔排布于1→4位键之间，13.0%的半乳糖位于非还原末端。

The compositions and FTIR spectral characteristics of hydrolysis product were studied using GC and FTIR. The results indicated that ASP3 is a kind of pectic polysaccharide which contained the main part of homogalacturonan fragments as "smooth regions" with galacturonic acid and rhaminose, and rhamnogalacturonan segments as "hairy regions" backbone. Galactose, arabinose, mannose and glucose were linked as arabinogalactan, galactan and arabinan, which were the mainly constitution of the branch.

实验结果表明，ASP3是一种果胶多糖，主要由光滑区和毛发区（富含中性糖侧链的鼠李半乳糖醛酸聚糖）两部分组成：GalA和Rha位于多糖分子的主链，由于Rha含量较低，大部分GalA相连形成半乳糖醛酸聚糖光滑区；Gal、Ara、Man及Glc位于多糖分子的支链，其中Gal以较高的聚合度与主链相连，Ara以还原性末端或低聚寡糖的形式与主链相连或与半乳聚糖末端相连形成阿拉伯半乳聚糖。

An inherited metabolic disorder characterized by the deficiency of an enzyme that is necessary for the metabolism of galactose.

半乳糖症一种遗传的代谢紊乱，因缺乏对半乳糖新陈代谢所必需的酶引起。

Galactose A sugar found in lactose and many polysaccharides. It is an aldohexose, isomeric with glucose.

半乳糖：是存在于乳糖和多糖中的一种六醛糖，为葡萄糖的同分异构体。

The obtaining of the recombinase gene can be used for gene alternation to obtain a novel Beta-galactoside synthase, thereby essentially improving the composing efficiency of a galactoside compound.

酶基因的获得，可用于基因改造获得新的β-半乳糖苷合成酶，从根本上提高半乳糖苷化合物的合成效率。
