WebThere are eight stereoisomers of 2,3,4,5-tetrahydroxypentanal, a group of compounds referred to as the aldopentoses. Since there are three chiral centers in this constitution, we should expect a maximum of 2 3 stereoisomers. These eight stereoisomers consist of four sets of enantiomers. WebAug 13, 2016 · Carbohydrates are built from carbon (C), oxygen (O) and hydrogen (H) atoms. Most carbohydrates can be described by the following chemical formula: C x H 2y O y. In other words, the number of hydrogen atoms is twice that of oxygen. The number of carbon atoms does not have to be related to the number of oxygen and hydrogen atoms.
