L'AMIDON, PRINCIPAL GLUCIDE DE RESERVE DES VEGETAUX SUPERIEURS ET L'UNE DES SOURCES CALORIQUES MAJEURES DE L'ESPECE HUMAINE, SE PRESENTE SOUS LA FORME DE GRAINS MICROSCOPIQUES (1-100 MICRONS) CONSTITUES D'UN MELANGE DE DEUX HOMOPOL YMERES DE GLUCOSE, L'UN LINEAIRE (L'AMYLOSE) ET L'AUTRE RAMIFIE (L'AMYLOPECTINE). LA CRISTALLINITE DE L'AMIDON NATIF (DE L'ORDRE DE 35%) TROUVE SON ORIGINE DANS L'ORGANISATION EN GRAPPE DE L'AMYLOPECTINE. LES COURTES BRANCHES DE LA MACROMOLECULE FORMENT DES DOUBLES HELICES QUI S'ASSOCIENT LATERALEMENT POUR FORMER DES LAMELLES CRISTALLINES. LA CARACTERISATION DE CES CRISTALLITES DANS LE GRAIN A UNE ECHELLE LOCALE RESTE PROBLEMATIQUE. POUR ETUDIER LA CRISTALLISATION DE L'AMIDON, ON PEUT AUSSI CONCEVOIR DES SYSTEMES...
