These are the 4 main types of carbon-based molecules necessary for life

The video tutorial explores the four major classes of carbon-based molecules: carbohydrates, lipids, proteins, and nucleic acids. It explains their structures, functions, and significance in life processes. Carbohydrates provide energy, lipids store energy and form cell structures, proteins perform diverse functions, and nucleic acids store genetic information.
