The incorporation of Ascorbic acid with the enzyme, adds hydroxyl group on proline residue in collagen.

抗坏血与酶的结，原中的脯氨残基上增加了羟基。

The researchers found a high concentration of the amino acid proline, which is abundant in dates and some other fruits.

研究人员发现了高浓度的脯氨，这种氨基在枣和其他水果中量丰富。

So proline that's had a hydroxyl molecule added to it.

脯氨中已经添加了一个羟基分子。

But it is high in glycine, proline, and hydroxyproline, which makes it very unique in structure.

但它富甘氨、脯氨和羟脯氨，这得它在结构上非常独特。

And then I want to say 10% is proline and then another like 10%-ish is hydroxyproline.

我想说 10% 是脯氨，另外大约 10% 是羟脯氨。

And so then I got thinking, Okay, that's I guess possible if you have more glycine and proline.

我就想， 好吧，我想如果有更多的甘氨和脯氨的话， 这是可能的。

He showed that the aldol reaction can be catalysed by a single amino acid, proline. And, crucially, this retains the enantiomeric purity of the enzyme-mediated reaction.

他证明了羟醛缩化反应可以被一种氨基--脯氨催化。最重要的是，这保留了酶介导反应的对映体纯度。

To start, collagen, comprised mainly of the amino acids glycine and proline, is one of the most abundant protein in our bodies, allocating roughly 25% of our total protein mass.

首先，原蛋白主要由甘氨和脯氨组成，这是我们体内最丰富的蛋白质之一，占我们总蛋白质总量的25%。

And then if you look at like whey protein versus collagen and the content of glycine and proline, I think collagen has like three to ten times the amount of glycine and proline in it compared to whey protein.

，如果您比较乳清蛋白和原蛋白中甘氨和脯氨的量，我认为原蛋白中的甘氨和脯氨的量是乳清蛋白的三到十倍。
