what are the four essential macromolecules of life and why?
56210
Biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions.

Of the 92 natural elements, 25 are essential for life. Of these, there are six main elements that are the fundamental building blocks of life. They are, in order of least to most common: sulfur, phosphorous, oxygen, nitrogen, carbon, and hydrogen. ... The basis of life is carbon.

All life on Earth is built from four different types of molecules. These four types of molecules are often referred to as the molecules of life. The four molecules of life are proteins, carbohydrates, lipids and nucleic acids. Each of the four groups is vital for every single organism on Earth.

Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.

There are four classes of macromolecules that constitute all living matter: carbohydrates, lipids, proteins, and nucleic acids. While they have different structures and functions, they are all composed of long complex chains of molecules (polymers) made up of simpler, smaller subunits (monomers).

Macronutrients on a Nutritional Label Macronutrients are essential substances that the body needs to survive and develop. There are 3 main macronutrients: fats, proteins, and carbohydrates. You can find information about these substances in the food that you eat by looking at the product's nutrition label.

All living things are made up of just four macromolecules: proteins, lipids, polysaccharides, and nucleic acids. Proteins are macromolecules made up of amino acid building blocks. There are thousands of proteins in organisms, and many are made up of several hundred amino acid monomers.

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. Combined, these molecules make up the majority of a cell's dry mass (recall that water makes up the majority of its complete mass).
