MACROMOLECULES
Macromolecules: Macromolecules are large, complex molecules that are fundamental to the structure and function of living organisms. They are essential for life, serving as the framework, energy source, and information carriers within cells. Let’s break down the four major categories of macromolecules and their roles. 1. Carbohydrates Structure : Composed of carbon, hydrogen, and oxygen in a ratio close to 1:2:1. Function : Provide energy and structural support. Examples : Glucose (energy source), starch (plant energy storage), cellulose (plant cell wall structure). 2. Proteins Structure : Made of amino acids linked by peptide bonds. Function : Perform a wide range of tasks including catalyzing reactions (enzymes), transporting molecules, and providing structural support. Examples : Hemoglobin (oxygen transport), collagen (structural protein), enzymes (biological catalysts). 3. Lipids Structure : Primarily composed of carbon and hydrogen, making them hydrophobic.
