Carbohydrates, most notably the polysaccharide cellulose, are the most abundant organic compounds on Earth. While often associated with energy, complex carbohydrates are crucial structural components that provide rigidity, strength, and protection to living organisms, from towering trees to microscopic bacteria. Their unique molecular structures enable them to form strong, durable frameworks essential for life.

Cellulose is the most abundant organic macromolecule on Earth and is a prime example of a carbohydrate with a structural role. Beyond serving as energy sources, certain carbohydrates provide vital structural support and protection in a wide variety of living organisms, from plants and fungi to insects and bacteria.

Over half of the organic carbon on Earth is contained within cellulose, a structural carbohydrate. So, what carbs are used for structural support? The answer lies in various complex polysaccharides found across different life forms, providing strength, rigidity, and protection to cells and entire organisms.

As the best-studied Gram-positive bacterium, *Bacillus subtilis* is a fascinating model organism for cellular research. This rod-shaped microbe, commonly found in soil, is a complex organism composed of a robust cell wall, a specialized cytoplasmic membrane, and intricate internal structures. Its specific composition allows it to thrive in varied environments and form highly resilient endospores under stress.

As one of the most widely studied probiotic strains, *Lactobacillus rhamnosus* GG has over 760 scientific publications detailing its functions and health benefits. However, to truly understand how this beneficial microbe works, one must explore its fundamental building blocks, from its complex cell wall structure to its specific genetic instructions. This exploration reveals a sophisticated cellular composition that enables its resilience and interaction with the human body.

Cellulose is the most abundant natural biopolymer on Earth and is a primary example of a carbohydrate with a structural function. This article answers the question, "Which of the following carbohydrates serves a structural function?" by exploring the key polysaccharides that provide support to various organisms and contrasting them with carbohydrates used for energy storage.

Cellulose is the most abundant natural biopolymer on Earth and is almost entirely made of glucose, demonstrating a key structural role for carbohydrates. This fundamental fact proves that not all carbohydrates are simply energy sources; indeed, some are essential building materials in living organisms, answering the question: can carbohydrates be used for structural functions?
