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

抗坏血酸与酶结合，使胶脯氨酸残基上增加了羟基。

2.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脯氨酸，这种氨基酸在枣和其他果含量丰富。

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

脯氨酸已经添加了一个羟基分子。机翻

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

然后说 10% 是脯氨酸，然后另外大约 10% 是羟脯氨酸。机翻

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

然后就， 好，如果有更多甘氨酸和脯氨酸话， 这是可能。机翻

6.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。最重要是，这保留了酶介导反应对映体纯度。

7.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，胶蛋白主要由甘氨酸和脯氨酸组成，这是们体内最丰富蛋白质之一，占们总蛋白质总量25%。

8.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.

然后，如果您比较乳清蛋白和胶蛋白甘氨酸和脯氨酸含量，认为胶蛋白甘氨酸和脯氨酸含量是乳清蛋白三到十倍。机翻
