I carried out several experiments on synthetic or biological samples, using different variants of XAS, such as XANES or EXAFS. I also used theoretical and numerical tools to interpret my data and compare them with those in the literature.In my book, I invite you to discover :- The base-off\/base-on reaction of cobalamines, which modifies the geometry and stability of cobalamines.- The interaction between haptocorrin and cobalamins, which involves a modification of cobalt coordination and protection against oxidation.- The photolysis reaction of alkylcobalamines, leading to the disruption of the cobalt-carbon bond and the formation of a free radical.- Synthesis and characterization of cobaloximes, \"model compounds of vitamin B12\".- The interaction between glutathione and cobalamins, leading to the formation of glutathione-cobalamin complexes.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786206648833\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786206648833","offer_id":47282567610693,"sku":"9786206648833","price":43.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/a447d201-5197-45aa-bf4a-ed9dccd45a5a.jpg?v=1750049375","url":"https:\/\/shop.autorenwelt.de\/products\/xas-powerful-spectroscopy-to-study-cobalamins-von-abdelhafid-mimouni","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
