This chlorophyll necklace in 18K gold vermeil is for the plant biologist, botanist or photosynthesis researcher who wants a quiet nod to her research, or for anyone who would like to give her one.\u003c\/p\u003e\n\n\u003ch2 style=\"margin-top:2em;\"\u003eThe Chemistry of Chlorophyll\u003c\/h2\u003e\n\u003cp\u003eChlorophyll a has two parts. A flat ring holds a magnesium ion at its centre and absorbs red and blue light. A long hydrocarbon tail called phytol anchors the molecule in the membranes inside the chloroplast. There, hundreds of chlorophylls sit bound to proteins in light-harvesting antennae. When one absorbs a photon, the energy hops from molecule to molecule until it reaches a reaction centre, where a special pair of chlorophylls gives up an electron. That handover is the first step in storing light as chemical energy, and it all happens in less than a billionth of a second.\u003c\/p\u003e\n\n\u003ch2 style=\"margin-top:2em;\"\u003eWho It's For\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ea plant biologist or botanist who wants to wear her field\u003c\/li\u003e\n\u003cli\u003ea PhD student in plant science, for her defence or graduation\u003c\/li\u003e\n\u003cli\u003ea keen gardener who loves the science behind it\u003c\/li\u003e\n\u003cli\u003esomeone who already wears the chlorophyll necklace in silver and wants the gold\u003c\/li\u003e\n\u003cli\u003eyourself, if gold is what you wear every day\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFrom a review of the silver version.

It comes on a 45 cm (17.7 inch) gold vermeil chain 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.

In 1960 they reported the first total synthesis of chlorophyll a, building the molecule step by step from simple starting materials. Richard Willstätter had worked out much of its composition decades earlier, and Hans Fischer had worked out most of its structure by 1940. Woodward received the 1965 Nobel Prize in Chemistry for his work in organic synthesis.\u003c\/p\u003e\n\u003c\/section\u003e\n","brand":"sciencejewelry1824","offers":[{"title":"Default Title","offer_id":56977552146818,"sku":"NK0405-GV","price":180.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1411\/4806\/files\/chlorophyll-gold-vermeil.png?v=1791900878","url":"https:\/\/sciencejewelry1824.shop\/products\/chlorophyll-gold-vermeil","provider":"sciencejewelry1824","version":"1.0","type":"link"}
