Mannóza

Mannóza is a type of sugar, specifically a monosaccharide. It is an epimer of glucose, meaning it differs in the configuration of a single hydroxyl group. Mannose is found in many fruits and is also a component of some glycoproteins, which are proteins that have carbohydrates covalently attached to them. It plays a role in various biological processes, including cell recognition and immune responses.

In humans, mannose is not a primary energy source like glucose. However, it is absorbed and can be utilized by the body. It is a component of the cell walls of yeast and certain bacteria, which has led to its use in some dietary supplements. These supplements are sometimes taken to support urinary tract health, although scientific evidence for this specific application is still developing.

The metabolism of mannose in the body involves its conversion to fructose-6-phosphate, which can then enter the glycolysis pathway for energy production. While not as abundant as glucose in the diet, mannose is present in a variety of foods, including berries, apples, peaches, and certain vegetables. Understanding mannose is important in the context of carbohydrate chemistry and its potential biological functions.
