LIFE SCIENCE

Detailed explanation-1: -There are 4 major biological macromolecules: proteins, lipids, carbohydrates, and nucleic acids. Each of these four has their own unique chemical structure and their own specific function within living organisms.

Detailed explanation-2: -11.1 Introduction: The Four Major Macromolecules Within all lifeforms on Earth, from the tiniest bacterium to the giant sperm whale, there are four major classes of organic macromolecules that are always found and are essential to life. These are the carbohydrates, lipids (or fats), proteins, and nucleic acids.

Detailed explanation-3: -The four types most important to human structure and function are carbohydrates, lipids, proteins, and nucleotides.

Detailed explanation-4: -Among the numerous types of organic compounds, four major categories are found in all living things: carbohydrates, lipids, proteins, and nucleic acids. Almost all organisms use carbohydrates as sources of energy. In addition, some carbohydrates serve as structural materials.

Detailed explanation-5: -There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions.
