What is considered a sugar?
Are formaldehyde and ketone bodies sugars?
Carbohydrates or sugars are another type of organic molecule, containing carbon, oxygen, and hydrogen. The name carbohydrate comes from the ratio of hydrogen to oxygen that is the same in these compounds as in water. In reality, the hydrogen and oxygen atoms are not arranged as they are in water, but primarily as alcohols. Ketones, aldehydes, and ether functional groups might also be present in suger
the suffix ose indicates that the substance is a sugar. Some simple sugars can be described (not named) based on the number of carbons (named with the same root as all organic molecules) and the ose suffix and a prefix of aldo if the sugar contains an aldehyde and keto if the sugar contains a ketone. These types of sugars can react with themselves, creating a hemiacetal from an alcohol group and the carbonyl group in the sugar. This reaction is called cyclization because a ring is also formed.
I hope this clears up the problem
so answer to your questionk, they are not suger, but a suger can have keton or aldehayde group.
That's right. They are not sugars by themselves (ketones and aldehydes), but they can be coupled through various reactions to incorporate sugars into their constituency. Ketose sugars and aldos were covered in my biochem lecture a few weeks back, so I can vouch for this as well.
It's the stuff I put in my latte cup every morning at 6.
