What organic compound is implicated in Diabetes mellitus?

In the context of Diabetes mellitus, ketones play a significant role, particularly in cases of poorly managed diabetes. When insulin is insufficient or absent, the body cannot effectively utilize glucose for energy. As a result, it begins to break down fats for fuel, leading to the production of ketones as byproducts of fat metabolism. Elevated levels of ketones can lead to a condition called ketoacidosis, which is a serious complication associated with diabetes, especially Type 1 diabetes.

While glucose is indeed a hallmark of diabetes, particularly in terms of monitoring blood sugar levels and managing the condition, it is the accumulation of ketones that is directly associated with the metabolic disturbances seen during episodes of insufficient insulin activity. Fructose and galactose, while also sugars, are not implicated in the pathological processes of diabetes in the same way ketones are. They are metabolized differently and do not lead to the same complications associated with ketone production in the context of diabetes management.
