What are methionine and glycine

Amino acid diagnostics

TryptophanPrecursors of serotonin and melatonin, therefore antidepressant and sleep-regulating; regulates pain sensation and appetite; contained in: cheese, fish, meat, legumes, oat flakes, cashew nuts, sunflower seeds, eggsPhenylalanineStarting material for catecholamine formation: L-phenylalanine → L-tyrosine → L-DOPA → dopamine → noradrenaline → adrenaline; contained in: soybeans, cheese, almonds, tuna, beef, eggsTyrosineessential; involved in the development of neurotransmitters: L-phenylalanine → L-tyrosine → L-DOPA → dopamine → noradrenaline → adrenaline; contained in: soybeans, cheese, almonds, tuna, beef, eggsGlycineforms glutathione together with glutamine and cysteine; involved in detoxification functions of the liver; increases uric acid excretion; antiarrhythmic; important for collagen formation; contained in: gelatine, soybeans, lentils, beef, peanuts, chicken eggsThreoninePrecursors to glycine and serine; contained in: buckwheat, peanuts, porkCystathioninegenerated by cystathionine-β-synthase from homocysteine ​​and serine; Increase indicates vitamin B6 deficiencyArginineis metabolized to nitric oxide, which has a vasodilatory effect and inhibits platelet aggregation; necessary for ammonia detoxification and for the synthesis of hormones (e.g. GH, prolactin, insulin, glucagon). contained in: pumpkin seeds, peanuts, almonds, soybeans, wheat germ, shrimp, beef, chickenCitrullinePart of the urea cycle, is converted to arginine; increased values ​​indicate acute nitrosative stress; contained in: melons, especially watermelons, cucurbits, cucumbers, onions, garlic, chickpeas, fish, meat, especially liverOrnithineIntermediate product in the urea cycle; can be used for ammonia detoxification; contained in: meat, fish, eggs and milkAsparaginePrecursor of the neurotransmitter aspartate; fixes toxic ammonia; contained in: potatoes, lentils, asparagus, almonds, spinachAlanineCan be used to synthesize glucose and regulate blood sugar levels by converting it into pyruvate; Contains: haddock, mackerel, herring, trout, perch, caviar, shrimp, eggs, cheeses such as Camembert, Gouda, Tilsiter
