Abstract

SE SUMINISTRAN COMPUESTOS QUE INCLUYEN UN POLIMERO POLISACARIDO SOLUBLE EN AGUA QUE TIENE UNA RELACION DE D-GLUCOSA:D-MANOSA:ACIDO D-GLUCURONICO DE ALREDEDOR DE 2:2:1. LAS MOLECULAS DE D-GLUCOSA ESTAN LIGADAS EN LA CONFIGURACION BETA-[1,4]. LAS MOLECULAS INTERIORES DE D-MANOSA ESTAN LIGADAS EN LA CONFIGURACION ALFA -[1,3], GENERALMENTE PARA ALTERNAR CON MOLECULAS DE GLUCOSA. LAS MOLECULAS DE ACIDO D-GLUCURONICO ESTAN LIGADAS EN LA CONFIGURACION BETA-[1,2] A LAS MOLECULAS DE MANOSA INTERIORES. LAS MOLECULAS DE MANOSA EXTERIORES ESTAN LIGADAS A LAS MOLECULAS DEL ACIDO GLUCURONICO EN UNA CONFIGURACION BETA-[1,4]. TAMBIEN SE SUMINISTRAN LOS PROCESOS PARA PREPARAR LOS POLIMEROS POLISACARIDOS.
