Amphora coffeaeformis var. perpusilla is able to concentrate but not metabolize mannose. The sugar, which can be accumulated against a concentration gradient, is taken up only after a short lag. Preincubation with glucose allows immediate mannose uptake. Substances that reduce the ATP content of the diatom cells also inhibit mannose uptake as do sugars of similar stereochemical configuration. Mannose appears to act as a non-metabolizable analogue of glucose in these respects.
微小咖啡双眉藻能够浓缩但不能代谢甘露糖。这种糖可以逆浓度梯度积累,仅在短暂延迟后才被吸收。用葡萄糖预孵育可使甘露糖立即被吸收。降低硅藻细胞ATP含量的物质也会抑制甘露糖的吸收,类似立体化学构型的糖也有同样的作用。在这些方面,甘露糖似乎起着葡萄糖的非代谢类似物的作用。
