l-脯氨酸(简称脯氨酸)是人体合成蛋白质的二十种氨基酸之一，常温下为无色至白色晶体或结晶性粉末，微臭，味微甜，易溶于水和乙醇，不溶于乙醚、丁醇和异丙醇，溶于无机酸。

Proline is biosynthetically derived from the amino acid L-glutamate. Glutamate-5-semialdehyde is first formed by glutamate 5-kinase (ATP-dependent) and glutamate-5-semialdehyde dehydrogenase (which requires NADH or NADPH).

Proline is an amino acid, or a building block for protein. The body can make proline on its own, but it is also consumed in the diet. A typical diet contains about 5 grams of proline daily....

2025年1月27日 · L-Proline is an amino acid and precursor (with vitamin C) for collagen, the building block of the structure of tendons, ligaments, arteries, veins and muscles. It is important in wound healing. Uses. L-Proline is used as asymmetric catalysts in organic synthesis and asymmetric aldol cyclization.

脯氨酸 （Proline，縮寫為 Pro 或 P ）是一個α- 氨基酸，又是一個環狀胺基酸，20個 DNA 編碼的其中之一。 它极易溶于水，微溶于乙醇、丙酮、苯，不溶于乙醚、丙醇。 虽然属于 蛋白胺基酸，并不是 伯胺 而是 仲胺 （旧称为 亞胺酸），因此具有特殊構象剛性，影響肽的 二級結構。 其對應 密碼子 為CCU、CCC、CCA和CCG。 脯氨酸不是一種 必需氨基酸，人體可以自行合成。 在20個蛋白質形成氨基酸中，其最特別之處在於胺氮被綁定到並非一個而是兩個烷基基團，因此 …

L-proline is pyrrolidine in which the pro-S hydrogen at position 2 is substituted by a carboxylic acid group. L-Proline is the only one of the twenty DNA-encoded amino acids which has a secondary amino group alpha to the carboxyl group. It is an essential component of collagen and is important for proper functioning of joints and tendons.

脯氨酸（Proline，缩写为Pro 或P），化学式为C5H9NO2，分子量为115.13，是一种环状的亚氨基酸。 α-亚氨基酸，中性，等电点为6.30，水中溶解度比任何氨基酸都大，25℃时100g水中可溶162g左右。

2021年1月12日 · What is L-Proline? L-proline is an amino acid. Scientists call it an “imino acid” or a “secondary” amino acid because of its unique chemical bonding structure as an essential element to collagen — a supportive protein for skin, bones, tendons, and connective tissue, supporting their health and healing.

2023年11月23日 · L-Proline - structure, chemical names, physical and chemical properties, classification, function

L-proline is an amino acid with a unique cyclic structure, involvement in various physiological processes, such as protein synthesis, collagen production, and neurotransmission. This review explores the complex roles of proline in the central nervous system …
