帕拉金糖是二糖，在D-葡萄糖和D-果糖之间有α（1→6）键，类似于蔗糖并具有及其蔗糖理化性质。它在某些细菌中通过蔗糖异构酶的作用从蔗糖转变而来。在哺乳动物的肠道，帕拉金糖的水解和吸收比蔗糖慢得多。 Palatinose is a disaccharide having an α(1→6) linkage between D-glucose and D-fructose and is similar to sucrose in its physicochemical properties. It is produced from sucrose in some bacteria by the action of sucrose isomerase. In mammalian gut, palatinose is hydrolyzed and absorbed much more slowly than sucrose.
