The distinguishing feature of ketoses is the presence of a carbonyl group (C=O) within the chain, typically at position 2 in the carbon backbone. This differentiates them from aldoses, which have an aldehyde group at the terminal position.<\/p>\n\n\n\n<p>Here are the details of the carbohydrates mentioned in the results and why some are ketoses:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fructose<\/strong>: This is a six-carbon sugar (hexose) and is a classic example of a ketose. The carbonyl group in fructose is located at the second carbon, making it a ketohexose.<\/li>\n\n\n\n<li><strong>Ribulose<\/strong>: Ribulose is a five-carbon sugar (pentose) and is another ketose. It has its carbonyl group at the second carbon, classifying it as a ketopentose.<\/li>\n\n\n\n<li><strong>Xylulose<\/strong>: Similar to ribulose, xylulose is a pentose sugar with a ketone group at the second carbon. Hence, it is also a ketopentose.<\/li>\n<\/ul>\n\n\n\n<p>On the other hand, aldoses like <strong>glucose<\/strong>, <strong>galactose<\/strong>, and <strong>ribose<\/strong> contain an aldehyde group at the terminal position and are therefore not classified as ketoses.<\/p>\n\n\n\n<p>In summary, ketoses have a ketone group at an internal carbon (usually the second carbon), while aldoses have an aldehyde group at the end. In Part B, the carbohydrates that are ketoses are fructose, ribulose, and xylulose due to the presence of their internal ketone groups.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>From the results in Part B, which carbohydrates are ketoses?
