Polysaccharides, long chains of monosaccharide units linked by glycosidic bonds, are crucial to life. The most abundant organic macromolecule on Earth, cellulose, is a key polysaccharide providing structural support to plants. But what are the four main examples of polysaccharides and how do they differ in function and composition?

While the chemical formula $C_1H_2O$ fits the general ratio for carbohydrates, the specific biomolecule matching this composition is formaldehyde, a simple but highly reactive aldehyde. Surprisingly, formaldehyde is produced naturally within the human body during various metabolic processes, though its levels must be carefully regulated due to its high toxicity.

Essential fatty acids are lipids that the human body cannot produce naturally and must obtain from dietary sources. For Class 11 biology students, understanding what essential fatty acids are is fundamental to grasping how cells function and the importance of a balanced diet. These vital fats play a crucial role in various biological processes, from building cell membranes to regulating inflammation.

Carbohydrates, also known as saccharides, are the most abundant biomolecules on Earth and serve as the primary source of energy for the body. This article provides a comprehensive overview for Class 12 students, breaking down the multifaceted functions these molecules perform in living organisms.
