Ketones
- We draw a carbon double-bonded to an oxygen atom and single-bonded to R groups on either side.
-Ketone groups are also found on simple sugars and participate in their ring-forming reaction because they are reactive.
-As a clinical correlate, ketosis occurs when ketone bodies are present in the blood, and may be caused by fasting, hypoglycemia, congenital disorders of metabolism, or a ketogenic diet like the Atkins diet. Ketoacidosis is an extreme version of ketosis and may be toxic because it lowers the pH of the blood significantly.
