请问D-乳酸的相关资料_百度知道

来自 : 百度知道 发布时间：2021-03-26

乳酸中只有L-乳酸才对人体有生理活性，在人体内只存在分解L-乳酸的酶，用于食品、医药的乳酸只能是L-乳酸。但人体某些新陈代谢过程中也会间接地产生D-乳酸。
--------------------------------------------------------------------------------------------
但在化工、轻工领域的乳酸，对其构型没有要求，也可能附带生产了一些D-乳酸。由于乳酸盐具有自然被降解的性质，我估计它可能的用途是合成乳酸酯类高聚物，用于食品的包装或者手术材料，或者其它日常生活用品。

因此实际上，工业上对D-乳酸的生产也是基于它能被自然降解这一特性。其具体生产厂商只搜到了2个：

Avery Lactate Company （纽约时报提到了这家公司，但不是很详细）。
其它厂商都是生产乳酸盐，或者准确地说，它们直接生产可降解材料，如：
