Question

What are the structures of common monosaccharides? 1) Ribose 2) Glucose 3) Mannose 4) Galactose 5) Fructose

Answer 1

The structures of common monosaccharides, including ribose, glucose, mannose, galactose, and fructose, are described.

Step-by-step explanation:

The structures of common monosaccharides are as follows:

1. Ribose has 5 carbon atoms in its chain, with an aldehyde group at one end. The chemical formula for ribose is C5H10O5.
2. Glucose has 6 carbon atoms in its chain, with an aldehyde group at one end. The chemical formula for glucose is C6H12O6.
3. Mannose has 6 carbon atoms in its chain, with an aldehyde group at one end. The chemical formula for mannose is C6H12O6.
4. Galactose has 6 carbon atoms in its chain, with an aldehyde group at one end. The chemical formula for galactose is C6H12O6.
5. Fructose has 6 carbon atoms in its chain, with a ketone group in the middle. The chemical formula for fructose is C6H12O6.
