What are the 4 biological macromolecule groups?
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.
What are the 4 classes of macromolecules give an example of each?
Proteins (polymers of amino acids) Carbohydrates (polymers of sugars) Lipids (polymers of lipid monomers) Nucleic acids (DNA and RNA; polymers of nucleotides)
What are the 4 main macromolecules and their functions?
The four main macromolecules are proteins, carbohydrates, nucleic acids and lipids. They are an important part of the cell and perform essential functions. Proteins are required for growth and maintenance, immunity and also act as enzymes, hormones, etc. Carbohydrates are the main energy source.
What are 4 classes of biological macromolecules and their building blocks?
Key Points. Biological macromolecules are important cellular components and perform a wide array of functions necessary for the survival and growth of living organisms. The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
What are biological macromolecules?
Biological macromolecules are large cellular components abundantly obtained naturally and are responsible for varieties of essential functions for the growth and survival of living organisms. There are four important classes of biological macromolecules, viz., carbohydrates, lipids, proteins, and nucleic acids.
What are macromolecules and what are the 4 types of macromolecules?
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. Combined, these molecules make up the majority of a cell’s mass.
What are the macromolecules explain each and give examples?
Types of biological macromolecules
| Biological macromolecule | Building blocks | Examples |
|---|---|---|
| Lipids | Fatty acids and glycerol | Fats, phospholipids, waxes, oils, grease, steroids |
| Proteins | Amino acids | Keratin (found in hair and nails), hormones, enzymes, antibodies |
| Nucleic acids | Nucleotides | DNA, RNA |
What are the main functions of macromolecules?
For example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions. Four major types of macromolecules—proteins, carbohydrates, nucleic acids, and lipids—play these important roles in the life of a cell.
Which of the four macromolecules is the most important?
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.
What elements are found in each of the major macromolecules?
Biological macromolecules are organic, meaning that they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, phosphorus, sulfur, and additional minor elements.
What is an example of a biological macromolecule?
Carbohydrates, proteins and nucleic acids are found as long polymers. Due to their polymeric nature and large size, they are known as macromolecules.
What are the four macromolecules important to life?
What is the function of biological macromolecules?
What is the structure of biological macromolecules?
1. Biological macromolecules are large and complex. Macromolecules are made up of basic molecular units. They include the proteins (polymers of amino acids), nucleic acids (polymers of nucleotides), carbohydrates (polymers of sugars) and lipids (with a variety of modular constituents).
How do you remember the 4 macromolecules?

What are the functions of the macromolecules?
How macromolecules are formed?
Biological macromolecules generally are polymers, (poly = many; mer = unit), formed by joining monomers, or single molecules, together in a long chain. They are formed by the process of polymerization. In this process, dehydration synthesis, or the removal of a water molecule, joins two monomers together (Figure 2.8).
What macromolecule is DNA?
Nucleic acids
Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in living organisms, all the way from single-celled bacteria to multicellular mammals like you and me.
What macromolecule is enzyme?
protein macromolecules
Enzymes are protein macromolecules. Proteins are large biopolymer molecules that are made up of repeating monomer units called amino acids.
Which macromolecule has the most energy?
Explanation: There are four classes of biological molecules: fats, carbohydrates, proteins, and nucleic acids. Of these, fats produce the most energy per gram at a whopping nine calories per gram.
Is DNA a protein?
No, DNA is not a protein. The major relationship between DNA and protein is that DNA encodes the information that is necessary to synthesize proteins. But DNA itself is not a protein. DNA is composed of long chains of nucleotides.
What are macromolecules also called?
Macromolecules are sometimes referred to as polymers which translates to “many” units and reflects that macromolecules are made of repeating monomer subunits. Examples of the four biological macromolecules of life are carbohydrates, lipids, nucleic acids, and proteins.
Why is it important to know the biological macromolecules?
Food provides the body with the nutrients it needs to survive. Many of these critical nutrients are biological macromolecules, or large molecules, necessary for life. These macromolecules (polymers) are built from different combinations of smaller organic molecules (monomers).
What is meant by biological macromolecules?
What is the importance of macromolecules?
Gigantic molecules, called macromolecules, populate a cell and provide it with important functions for life. For example, macromolecules provide structural support, a source of stored fuel, the ability to store and retrieve genetic information, and the ability to speed biochemical reactions.
