Web11 apr. 2024 · hydroxyl group (―OH), in chemistry, a functional group with one hydrogen and one oxygen atom. An oxygen atom normally forms two σ bonds with other atoms; the water molecule, H2O, is the simplest and most common example. If one hydrogen atom is removed from a water molecule, a hydroxyl functional group (―OH) is generated. … Web4 feb. 2024 · Carbohydrates are broadly classified into two subgroups, “simple” and “complex". Simple carbohydrates are grouped into monosaccharides and disaccharides. The simplest unit of a carbohydrate is a monosaccharide.

As described above, one way of classifying monosaccharides is using functional groups present in the molecule. Therefore, if the monosaccharide has a ketone group, it is called a ketose. WebIf the hydroxyl group in the projection formula pointed to the right, it was defined as a member of the D-family. A left directed hydroxyl group (the mirror image) then represented the L-family.
