Chemical modifications of galactomannans: synthesis and structure-function analysis: Chemical modifications of galactomannans
Galactomannans (GM) are multifunctional polysaccharides made up of a β (1→4)-D-mannopyranose backbone with D-galactopyranose branches linked by α (1→6) glycosidic bonds. They are obtained from the endosperm of seeds of plants by different extraction methods. GM are natural products of carbon fixatio...

Los galactomananos (GM) son polisacáridos multifuncionales formados por una cadena de β (1→4)-D-manopiranosa con ramificaciones de D-galactopiranosa unidas por enlaces glucosídicos α (1→6). Se obtienen del endospermo de semillas de leguminosas por diferentes métodos de extracción. Los GM son productos naturales de la fijación de carbono a través de una serie de vías biosintéticas a gran escala. La modificación química de polisacáridos se ha utilizado como estrategia para cambiar características estructurales y propiedades funcionales, como solubilidad, polaridad, carga iónica, bioactividad, entre otras. Las modificaciones reportadas de GM incluyen hidrólisis, esterificación, eterificación y adición de grupos funcionales como sulfatos o fosfatos que originan derivados de GM con potencial de aplicación biológica y tecnológica. Por lo tanto, esta revisión se centra en las rutas sintéticas y el análisis de las estructuras químicas de los GM modificados químicamente.
