Questions & Step-by-Step Solutions
Which of the following carbohydrates is a ketose?
Step 1: Understand what carbohydrates are. Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen.
Step 2: Learn about the two main types of simple sugars: aldoses and ketoses.
Step 3: Know that aldoses have an aldehyde group (-CHO) at one end, while ketoses have a ketone group (C=O) somewhere in the middle.
Step 4: Identify the sugars in the question: glucose, galactose, and fructose.
Step 5: Determine the type of each sugar: glucose and galactose are aldoses because they have an aldehyde group, while fructose is a ketose because it has a ketone group.
Step 6: Conclude that fructose is the ketose sugar among the options given.
