Tag: Amino sugars

Did you know that many important biomolecules, like DNA, contain modified sugar units rather than simple sugars? The different types of derived carbohydrates are sugars that have undergone chemical modification, giving them new structures and functions critical to biological processes.

An amino sugar is a sugar molecule containing an amino group, and of the many varieties that exist, three are particularly common in nature: glucosamine, galactosamine, and mannosamine. These carbohydrate derivatives are fundamental building blocks for many larger biological structures, from the exoskeletons of insects to the connective tissues within the human body. Understanding these molecules is key to grasping the complexities of biological processes.

Historically, carbohydrates were defined by the empirical formula $C_x(H_2O)_y$, which suggested they were simple 'hydrates of carbon'. While this holds true for basic monosaccharides like glucose ($C_6H_{12}O_6$), many complex and modified carbohydrates in nature contain additional elements.
