Aspartate transaminase (AST) or aspartate aminotransferase, also known as AspAT/ASAT/AAT or (serum) glutamic oxaloacetic transaminase (GOT, SGOT), is a pyridoxal phosphate (PLP)-dependent transaminase enzyme (EC 2.6.1.1) that was first described by Arthur Karmen and colleagues in 1954. [1][2][3] AST catalyzes the reversible transfer of an α ...
Elevated transaminases. Alanine transaminase is one of the two transaminases measured (Aspartate transaminase is the other). In medicine, the presence of elevated transaminases, commonly the transaminases alanine transaminase (ALT) and aspartate transaminase (AST), may be an indicator of liver dysfunction. [1][2] Other terms include ...
Alanine transaminase (ALT), also known as alanine aminotransferase (ALT or ALAT), formerly serum glutamate-pyruvate transaminase (GPT) or serum glutamic-pyruvic transaminase (SGPT), is a transaminase enzyme (EC 2.6.1.2) that was first characterized in the mid-1950s by Arthur Karmen and colleagues. [1] ALT is found in plasma and in various body ...
003436. [edit on Wikidata] Liver function tests (LFTs or LFs), also referred to as a hepatic panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin, bilirubin (direct and indirect), and others.
Glutamate receptors serve to facilitate the impact of the neurotransmitter glutamate in the central nervous system. These receptors are pivotal in excitatory synaptic transmission, synaptic plasticity, and neuronal development. They are vital for functions like learning, memory, and neuronal communication. [13]
Glutamate is a very major constituent of a wide variety of proteins; consequently it is one of the most abundant amino acids in the human body. [1] Glutamate is formally classified as a non-essential amino acid, because it can be synthesized (in sufficient quantities for health) from α-ketoglutaric acid, which is produced as part of the citric acid cycle by a series of reactions whose ...
Women are more likely to deal with restless legs syndrome than men. ... estrogen influences the transmission of dopamine and glutamate (a neurotransmitter involved in brain function), sparking ...
The end product of the glutaminase reaction, glutamate, is a strong inhibitor of the reaction. Changes in glutamate dehydrogenase, which converts glutamate to 2-oxoglutarate and thereby decreases intramitochondrial glutamate levels, are thereby an important regulatory mechanism of glutaminase activity.
