It is also the brain's main excitatory messenger, the signal that tells the next neuron to fire. So how does the brain keep its own signal apart from what is on the plate? Most of the glutamate you eat never gets past the gut, because the cells lining the intestine use most of it as fuel. The little that reaches the blood meets the blood-brain barrier, which lets almost none through and actively pumps glutamate out of the brain. Neurons make their own from glucose and glutamine instead, and keep it packed in tiny vesicles until the moment they release it.\u003c\/p\u003e\n\n\u003ch2 style=\"margin-top:2em;\"\u003eExplore Related Molecules Jewelry\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/glutamate\"\u003eglutamate necklace | silver\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/gaba-necklace-gold-vermeil\"\u003eGABA necklace | gold vermeil\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/ketamine-necklace-gold-vermeil\"\u003eketamine necklace | gold vermeil\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sciencejewelry1824.shop\/products\/neuron-18k-gold-plated\"\u003eneuron necklace | gold vermeil\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003csection class=\"product-faq\"\u003e\n\u003ch2 style=\"margin-top:2em;\"\u003eFAQ\u003c\/h2\u003e\n\n\u003ch3 style=\"margin-top:1.75em;\"\u003eHow big is the pendant, and what chain comes with it?\u003c\/h3\u003e\n\u003cp\u003eThe pendant is 28 mm (about 1.1 inches), a little larger than a 2-euro coin. It hangs from a single loop at the top and sits just below the collarbone. The chain is 45 cm (17.7 inches) of gold vermeil with a lobster clasp and a 5 cm (2 inch) extender. 18K gold vermeil means 2.5 microns of 18K gold over solid sterling silver, nickel-free and hypoallergenic.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-top:1.75em;\"\u003eIs there a silver version?\u003c\/h3\u003e\n\u003cp\u003eYes. The glutamate necklace also comes in sterling silver, at the same 28 mm on the same 45 cm chain with a 5 cm extender, and sits just below the collarbone in the same way. Choose the finish the recipient already wears: the design is the same in both.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-top:1.75em;\"\u003eIs delivery free, and what if it isn't right?\u003c\/h3\u003e\n\u003cp\u003eYes. DHL Express delivers free in 1-5 business days worldwide, and we pay the import duties and taxes, so nothing is due at the door. It arrives in a ready-to-gift jewelry box and festive envelope. If it isn't right, our 30-day “Love It or Return It” policy applies.\u003c\/p\u003e\n\n\u003ch3 style=\"margin-top:1.75em;\"\u003eWhy did it take so long to accept glutamate as a neurotransmitter?\u003c\/h3\u003e\n\u003cp\u003eBecause it was everywhere. In 1954 the Japanese physiologist Takashi Hayashi reported that glutamate applied to the brain of dogs and monkeys set off seizures. In 1959 David Curtis, John Phillis and Jeffrey Watkins in Canberra showed that it excites nerve cells in the spinal cord. But every cell uses glutamate to build proteins, so even the Canberra team doubted something so common could carry a precise signal. Only in the late 1970s and early 1980s, when drugs that block its receptors were found, did most scientists accept it.\u003c\/p\u003e\n\u003c\/section\u003e\n","brand":"sciencejewelry1824","offers":[{"title":"Default Title","offer_id":57028980048258,"sku":"NK0421-GV","price":180.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1411\/4806\/files\/glutamate-gold-vermeil.png?v=1794401957","url":"https:\/\/sciencejewelry1824.shop\/products\/glutamate-gold-vermeil","provider":"sciencejewelry1824","version":"1.0","type":"link"}
