Abstract
"oligossacarídeo alginato e seus derivados, sua preparação e seus usos". o presente estudo fornece um oligossacarídeo alginato e seus derivados com grau de polimerização variando de 2 a 22. o oligossacarídeo alginato é composto de ácido manurônico ligado a ácido b-d-manurônico por ligações glicídicas 1,4. os derivados com terminal reduzido na posição 1 do radical carboxila pode ser preparado por degradação oxidativa. o presente estudo também fornece um processo para preparar o oligossacarídeo alginato e seus derivados, que inclui os procedimentos em que uma solução de alginato é reagida por 2 a 6 h num autoclave a ph 2-6 e temperatura de 100-120?, e o ph é ajustado para 7 após a reação ser interrompida, após o que o oligossacarídeo resultante é oxidado na presença de um oxidante para obter um produto da degradação oxidativa. o oligossacarídeo alginato e seus derivados deste método podem ser usados na manufatura de um medicamente para a profilaxia e tratamento de ma e diabetes.
