Finally, there's the monosaccharide, galactose, known as milk sugar.

最后还有一种单叫，常与相提并论。

Among these are serine and threonine residues which are O-linked glycosylated, meaning they have a sugar molecule, specifically galactose, attached to their oxygen.

其中有丝氨酸苏氨酸残基，o基化的，意味着它们的氧上有一个分子，居多。

Now, lactose is a dye saccharide sugar, meaning it's composed of two simple sugar building blocks, glucose and galactose.

一种染料，意味着它由两个简单的块组成，葡萄。

These include glucose, fructose, and galactose.

单的种类有葡萄、果。

Just like that galactose has become just one more glucose molecule in the liver.

通过种方式变成了可供肝脏利用的葡萄。

Lactose on the other hand has a beta 1-4 glycosidic bond, meaning that carbon 1 of galactose and carbon 4 of glucose are bonded, but this time the molecules are stacked with one higher than the other.

中的苷键为β-1，4苷键，即分子的1号碳与葡萄分子的4号碳以苷键相连，β代表了两个分子上下交叠，一高一低。

For example, in honey 50% of the sugar is fructose, 44% is glucose, 4% is galactose, 2% is maltose; whereas in maple syrup less than 1% of the sugar is fructose, 3% is glucose, and 96% is sucrose.

举个例子，蜂蜜中含有50%的果、44%的葡萄、4%的与2%的麦芽；而枫浆中，果的含量不到1%，葡萄仅占3%，其余的96%都蔗。

There are oligosaccharides like galacto-oligosaccharides which are short chains of galactose molecules like those found in soybeans.

低聚就一种寡，在大豆中含量较高，由数个分子结合形成的短分子。

A molecular mass of 180 could be either the glucose, galactose or fructose.

分子质量为180可能葡萄、或果。

It’s called galactose oligosaccharide, also known as the Gal antigen.

它被称为寡，也称为Gal抗原。

Now, metabolism of galactose has an initial step where an enzyme in the liver converts galactose into glucose - basically flipping the orientation of the OH group on the 4th carbon.

代谢的第一步在肝脏中，通过酶的作用，将转化为葡萄，其实就把的4号碳上的-OH键调个方向。
