Question

1. identify aldose vs ketose

Explanation:

Aldoses are monosaccharides that contain an aldehyde functional group ($-\text{CHO}$) at one end of their carbon chain. Ketoses are monosaccharides that contain a ketone functional group ($\text{C=O}$) located somewhere in the middle of their carbon chain (not at the terminal position).

Answer:

• Aldose: A monosaccharide with an aldehyde group ($-\text{CHO}$) at the terminal carbon.
• Ketose: A monosaccharide with an internal ketone group ($\text{C=O}$).
