Aspartic acid (symbol Asp or D; [4] the ionic form is known as aspartate), is an α-amino acid that is used in the biosynthesis of proteins. [5] The L-isomer of aspartic acid is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. D-aspartic acid is one of two D-amino acids commonly found in mammals.

天门冬氨酸 （英語： Aspartic acid，可簡寫為Asp或D），简称 天冬氨酸，药学中多简称 门冬氨酸，是一种α-氨基酸，其化學式為HOOCCH 2 CH (NH 2)COOH。 天冬氨酸的L- 異構物 是20种 蛋白胺基酸 之一，即 蛋白質 的构造单位。 它的 密碼子 是GAU和GAC。 它与 谷氨酸 同為 酸性氨基酸。 天冬氨酸普遍存在于生物合成作用中。 最初就是在蘆筍中被發現此胺基酸， 蘆筍 （Asparagus officinalis）屬於天門冬屬，富含天門冬胺酸，故以其英文名稱命名為天門冬胺酸 aspartic …

2024年11月17日 · Aspartate transaminase (AST), also known as aspartate aminotransferase, is a crucial enzyme in the body involved in the metabolism of amino acids. It plays a significant role in the interconversion of amino acids and α-keto acids, which are …

2022年1月1日 · Asx、B可代表天冬氨酸（Asp、D）或天冬酰胺（Asn、N）。 Glx、Z可代表谷氨酸（Glu、E）或谷氨酰胺（Gln、Q）。 Xle、J可代表亮氨酸（Leu、L）或异亮氨酸（Ile、I）。

The amino acid serves as a precursor for synthesis of proteins, oligopeptides, purines, pyrimidines, nucleic acids and L-arginine. L-aspartate is a glycogenic amino acid, and it can also promote energy production via its metabolism in the Krebs cycle.

L-aspartic acid is an amino acid, which are the building blocks of protein. D-aspartic acid is used in other body functions. Aspartate refers to both forms. L-aspartic acid is a nonessential...

Aspartic acid exists in L- and D-isoforms (L-Asp and D-Asp). Most L-Asp is synthesized by mitochondrial aspartate aminotransferase from oxaloacetate and glutamate acquired by glutamine deamidation, particularly in the liver and tumor cells, and transamination of branched-chain amino acids (BCAAs), particularly in muscles.

Aspartic acid is one of two acidic amino acids. Aspartic acid and glutamic acid play important roles as general acids in enzyme active centers, as well as in maintaining the solubility and ionic character of proteins.

Aspartic acid (aspartate, Asp) is a biologically non-essential amino acid identified by the hydrolysis of asparagine. Aspartate comprises two isoforms: the predominant form is L-aspartic acid (L-Asp) , while D-aspartic acid (D-Asp) is found in somewhat lesser quantities.
