Bonjour,

Je ne comprends pourquoi cet item est faux:

"Les chromoprotéines se caractérisent par la présence d'un noyau porphyrinique." 

L'heme = noyau tetrapyrole = noyau porphyrine, non ?

coucouuuu, parce que t'as des chromoprotéines porphyriniques (l'hémoglobine notamment) et des chromoprotéines non porphyriniques (la ferritine par ex je crois), c'est noté dans ses diapos 😉
