Crystalline monosodium glutamate (MSG) Glutamate flavoring is the generic name for flavor-enhancing compounds based on glutamic acid and its salts (glutamates). These compounds provide an umami (savory) taste to food. Glutamic acid and glutamates are natural constituents of many fermented or aged foods, including soy sauce, fermented bean paste ...
First, γ-glutamylcysteine is synthesized from L-glutamate and L-cysteine. This conversion requires the enzyme glutamate–cysteine ligase (GCL, glutamate cysteine synthase). This reaction is the rate-limiting step in glutathione synthesis. [3] Second, glycine is added to the C-terminal of γ-glutamylcysteine.
Treatment is administered during the acute stages of excitotoxic shock along with glutamate antagonists. Dehydration should be avoided as this also contributes to the concentrations of glutamate in the inter-synaptic cleft [7] and "status epilepticus can also be triggered by a build up of glutamate around inter-synaptic neurons." [8]
Generally, umami taste is common to foods that contain high levels of L-glutamate, IMP and GMP, most notably in fish, shellfish, cured meats, meat extracts, mushrooms, vegetables (e.g., ripe tomatoes, Chinese cabbage, spinach, celery, etc.), green tea, hydrolyzed vegetable protein, and fermented and aged products involving bacterial or yeast ...
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.
Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues.

The regulatory status of theanine varies by country. In Japan, L-theanine has been approved for use in all foods, with some restrictions in the case of infant foods. [11] [23] In the United States, the FDA considers it to be GRAS and allows its use as an ingredient in dietary supplements or foods up to a maximum of 250 mg per serving. [4]
Poor diet in early childhood affects the number of neurons in parts of the brain. [1]Nutritional neuroscience is the scientific discipline that studies the effects various components of the diet such as minerals, vitamins, protein, carbohydrates, fats, dietary supplements, synthetic hormones, and food additives have on neurochemistry, neurobiology, behavior, and cognition.
