Acyclic polyols (erythritol, xylitol, ribitol, D-arabinitol, mannitol, sorbitol and galactitol) are not metabolized by Saccharomyces cerevisiae. They are taken up by a fast non-active process, reaching 40-70% distribution referred to total cell water. The uptake is insensitive to temperature, pH (between 4 and 8), 2,4-dinitrophenol and uranyl ions. Its initial rate rises linearly with concentration from 10(-5)M to 1M. The process resembles simple diffusion through large pores or the trapping of the whole solution on the surface. Protoplasts behave like whole cells in this respect. Only erythritol shows a second type of uptake which is inhibitor-insensitive but temperature-dependent.
无环多元醇（赤藓糖醇、木糖醇、核糖醇、D-阿拉伯糖醇、甘露醇、山梨醇和半乳糖醇）不能被酿酒酵母代谢。它们通过快速非活性过程被吸收，相对于总细胞水达到40 - 70%的分布。这种吸收对温度、pH值（4至8之间）、2,4 - 二硝基苯酚和铀离子不敏感。其初始速率随浓度从10⁻⁵M到1M呈线性上升。该过程类似于通过大孔的简单扩散或整个溶液在表面的截留。在这方面，原生质体的行为与完整细胞相似。只有赤藓糖醇表现出第二种吸收类型，这种吸收对抑制剂不敏感，但依赖于温度。
