Understanding “Ose-Type” Sugars: Dextrose, Glucose, Fructose, Sucrose, and More
Sugar, in all its many forms, is ubiquitous in the modern diet. Whether it’s the naturally occurring sweetness of fruit or the added sugars in processed foods, these “ose-type” sugars—glucose, dextrose, fructose, sucrose, and others—play a significant role in food chemistry, metabolism, and health.
While they may seem interchangeable, each of these sugars has distinct chemical structures, metabolic pathways, and effects on the body. Let’s break down their differences, examine their chemical compositions, and explore the top foods that contain them.
1. Glucose (C₆H₁₂O₆)
What is it?
Glucose is a simple sugar (monosaccharide) that serves as the primary energy source for the body. It is absorbed directly into the bloodstream during digestion and used by cells for energy production.
How it Functions
- Glucose is the sugar measured in blood sugar levels.
- It is metabolized by nearly every cell in the body.
- The pancreas releases insulin in response to glucose to regulate blood sugar levels.
