Bonjour,

qcm 1, item A je ne comprend pas la correction qui dit que comme la liaison amide n’est pas hydrolysable on aura pas darachidonate de sodium. Mais je ne comprend pas d’où sortirai larachidonate de sodium dans les réactifs on a pas darachidonate donc il faut savoir un teuc sur ça, genre il apparaît après une réaction ou je sais pas ?

merciii
