1·The most important representatives of monosacchrides are glucose, arabinose, galactose, mannose, ribose, and fructose.
最有代表性的单糖是葡萄糖、阿拉伯糖、半乳糖、甘露糖、核糖和果糖。
2·The ribose of one nucleotide joins with the phosphate of the next to form the RNA backbone.
一个核的核糖和下一个磷酸盐相连，形成核糖核酸的支柱。
3·The mutant had entirely lost transketolase activity and could accumulate a large amount of D? ribose in the culture medium. The amount of D?
与亲株相比，该菌株完全丧失了转酮醇酶活性，能够在培养基中大量积累D 核糖。
4·The transketolase affected Bacillus mutant couldn't grow on the media, which used gluconic acid as sole carbon source, while it showed a potential to convert gluconic acid into D ribose.
枯草芽孢杆菌转酮酶缺陷突变株不能以D-葡萄糖酸为唯一碳源生长，但其作为D-核糖的前体则是有效的。
5·They can't ferment glucose, fructose, esculin, amygdalin, arabinose, lactose, mannose, ribose, sucrose, xylose, raffinose, mannitol, inositol, sorbitol and gelatin.
