2021年3月24日 · The basic and primary difference would be that aspartic acid has The C4 carbon is in Aspartic acid while Asparagine has an amide group. Asparagine residues can be changed to build complex carbohydrate chains and is important for that reason. It can also form into cycle within a peptide or protein to form an amide that opens to form aspartic acid.

The enzyme asparagine synthetase produces asparagine, AMP, glutamate, and pyrophosphate from aspartate, glutamine, and ATP. Asparagine synthetase uses ATP to activate aspartate, forming β-aspartyl-AMP.

癫痫和脑中风 N-甲基-D天门冬氨酸(N- Methyl-D- Aspartic Acid)是天门冬氨酸的高能量形式，被用来诱发实验动物的癫痫发作。但这种化合物的对手是2—氨基—7—膦酰基庚酸（2- amino-7- phospho heptanoic acid，注3)充当抗惊厥药物的拮抗剂，可阻断癫痫的发作。

Asparagine vs aspartic acid (aspartate) Asparagine is neutral at physiological pH (~7) due to the deprotonation of the carboxyl group on the backbone ( -COO-), the protonation of the amino group (-NH 3 +), and the non-ionization of the carboxamide side chain (-CONH 2).

2024年3月21日 · Aspartic acid (Asp/D) is a non-essential amino acid with a carboxyl group in its Rgroup. It is readily produced by transamination of oxaloacetate. With a pKa of 3.9, aspartic acid’s side chain is negatively charged at physiological pH. Aspartic acid is specified in the genetic code by the codons GAU and GAC.

2020年4月9日 · Here, we report that p53 suppresses asparagine synthesis through the transcriptional downregulation of ASNS expression and disrupts asparagine-aspartate homeostasis, leading to lymphoma and...

Asparagine, an amino acid closely related to aspartic acid, and an important component of proteins. First isolated in 1932 from asparagus, from which its name is derived, asparagine is widely distributed in plant proteins. It is one of several so-called nonessential amino acids in …

Asparagine and aspartate homeostasis are linked with type 2 diabetes (T2D). This study aimed to explore whether asparagine and aspartate metabolism interacted with sex and age to increase the risk of T2D.

2023年1月2日 · Asparagine is a non-essential amino acid used for biosynthesis of proteins. Its precursor, OAA, is converted into aspartate by an enzyme called asparagine synthetase. Asparagine synthetase is a glutamine-dependent enzyme that catalyzes the asparagine biosynthesis process.

Substitutions: Asparagine is a polar amino acid. It thus most prefers to substitute for other polar residues, in particular Aspartate, which differs only in that it contains an oxygen in place of the amino group in Asparagine. It can also substitute with other polar amino acids.
