In enzymology, a L-glutamate oxidase (EC 1.4.3.11) is an enzyme that catalyzes the chemical reaction L-glutamate + O 2 + H 2 O ⇌ {\displaystyle \rightleftharpoons } 2-oxoglutarate + NH 3 + H 2 O 2 The 3 substrates of this enzyme are L-glutamate , O 2 , and H 2 O , whereas its 3 products are 2-oxoglutarate , NH 3 , and H 2 O 2 .
As of 2016, the International Society for the Study of the Aging Male defines late-onset hypogonadism as a series of symptoms in older adults related to testosterone deficiency that combines features of both primary and secondary hypogonadism; the European Male Aging Study (a prospective study of ~3000 men) [10] defined the condition by the presence of at least three sexual symptoms (e.g ...
Porphyria / p ɔːr ˈ f ɪr i ə / is a group of disorders in which substances called porphyrins build up in the body, adversely affecting the skin or nervous system. [1] The types that affect the nervous system are also known as acute porphyria, as symptoms are rapid in onset and short in duration. [1]
Due to the range of glutamate function and presence, it has been difficult to create glutamatergic drugs that do not negatively affect other necessary functions and cause unwanted side-effects. [41] NAAG peptidase inhibition has offered the possibility for specific drug targeting.
Treatment for glycogen storage disease type III may involve a high-protein diet, to facilitate gluconeogenesis. Additionally the individual may need: [2] [1] [10] IV glucose (if oral route is inadvisable) Nutritional specialist; Vitamin D (for osteoporosis/secondary complication) Hepatic transplant (if a complication occurs)
Glutamate is the most prominent neurotransmitter in the body, and is the main excitatory neurotransmitter, being present in over 50% of nervous tissue. [2] [3] Glutamate was initially discovered to be a neurotransmitter in insect studies in the early 1960s.
The side-effects profile varies for different patient populations. [50] Overall adverse effects in treatment are similar between men, women, geriatric, pediatric, and racial groups. [5] Lamotrigine has been associated with a decrease in white blood cell count . [53] Lamotrigine does not prolong QT/QTc in TQT studies in healthy subjects. [54]
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.
