Glutaric acidemia type 1 (GA1) is an inherited disorder in which the body is unable to completely break down the amino acids lysine, hydroxylysine and tryptophan.Excessive levels of their intermediate breakdown products (glutaric acid, glutaryl-CoA, 3-hydroxyglutaric acid, glutaconic acid) can accumulate and cause damage to the brain (and also other organs [1]), but particularly the basal ...
Glutamic acid (symbol Glu or E; [4] the anionic form is known as glutamate) is an α-amino acid that is used by almost all living beings in the biosynthesis of proteins.It is a non-essential nutrient for humans, meaning that the human body can synthesize enough for its use.
Glutaric acidemia type 2 has an autosomal recessive pattern of inheritance. Mutations in the ETFA, ETFB, and ETFDH genes cause glutaric acidemia type II. Mutations in these genes result in a deficiency in one of two enzymes that normally work together in the mitochondria, which are the energy-producing centers of cells.
Formiminoglutamic acid (FIGLU; conjugate base, formiminoglutamate) is an intermediate in the catabolism of L-histidine to L-glutamic acid. It thus is also a biomarker for intracellular levels of folate. The FIGLU test is used to identify vitamin B₁₂ deficiency, folate deficiency, and liver failure or liver disease.
Hemoglobin C (abbreviated as HbC) is an abnormal hemoglobin in which glutamic acid residue at the 6th position of the β-globin chain is replaced with a lysine residue due to a point mutation in the HBB gene. [1] People with one copy of the gene for hemoglobin C do not experience symptoms, but can pass the abnormal gene on to their children.
Triose phosphate isomerase deficiency is characterized by chronic hemolytic anemia. While there are various mutations that cause this disease, most include the replacement of glutamic acid at position 104 with an aspartic acid. [1]
Carbamoyl phosphate synthase 1, abbreviated as CPS1, is activated by its natural activator N-acetyl glutamate, which in turn is synthesized from acetyl-CoA and glutamic acid in the reaction catalyzed by N-acetyl glutamate synthase, commonly called NAGS. N-acetyl glutamate is required for the urea cycle to take place.
Mild glutathione synthetase deficiency usually results in the destruction of red blood cells (hemolytic anemia). Rarely, affected people also excrete large amounts of a compound called 5-oxoproline (also called pyroglutamic acid, or pyroglutamate) in their urine (5-oxoprolinuria). This compound builds up when glutathione is not processed ...
