In this episode of Bio On The Go, we dive into the essential elements of life (CED 1.2) and kick off our macromolecule series with a deep look at carbohydrates (CED 1.3). What exactly are macromolecules, and why are they so important for life? We’ll break it down starting with carbon—the versatile backbone of biological molecules—and walk through the structure, function, and examples of carbohydrates. From monosaccharides to polysaccharides, you'll learn how sugar isn’t just sweet—it’s essential. Perfect for review, reinforcement, or getting ahead, this episode keeps it short, sharp, and student-friendly.
