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

抗坏血酸与酶的结合，使胶原中的脯氨酸残基上增加了羟基。

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

人员发现了高浓度的脯氨酸，这种氨基酸在枣和其他果中含量丰富。

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

脯氨酸中已经添加了一个羟基分子。

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

然说 10% 是脯氨酸，然另外大约 10% 是羟脯氨酸。

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

然就， 好吧，如果有更多的甘氨酸和脯氨酸的话， 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酸--脯氨酸催化。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，胶原蛋白主要由甘氨酸和脯氨酸组成，这是们体内最丰富的蛋白质之一，占们总蛋白质总量的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.

然，如果您比较乳清蛋白和胶原蛋白中甘氨酸和脯氨酸的含量，认为胶原蛋白中的甘氨酸和脯氨酸的含量是乳清蛋白的三到十倍。
