What are the 3 main molecules of life?

Living organisms, and most of our food, provide a mixture of all different kinds of organic molecules. Three of them, carbohydrates, proteins, and nucleic acids, are regarded as macromolecules. Most macromolecules are polymers, which are made by stringing together many smaller molecules called monomers.

What are 3 types of molecules?

There are three types of molecules which are the element molecule, the compound molecule & the mixture.

What is the most important molecule on Earth?

Water is one of the most unique molecules known to man and also one of the most important to biological systems. Not only does water exist in nature in all three states of matter (solid, liquid, gas), it also covers 75 percent of the earth and composes roughly 78 percent of the human body.

What are the 4 molecules of life?


  • Lipids.
  • Nucleic acids.
  • Proteins.
  • What is biomolecules of life?

    Biomolecules are an organic molecule that includes carbohydrates, protein, lipids, and nucleic acids. They are important for the survival of living cells. Some of valuable biomolecules have huge demand, which cannot be fulfilled from their renewable resources.

    What is the job of a molecule?

    A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.

    What is the largest molecule in our bodies?

    These vary in size from simple pairs of atoms, like an oxygen molecule, to complex organic structures. But the biggest molecule in nature resides in your body. It is chromosome 1. A normal human cell has 23 pairs of chromosomes in its nucleus, each a single, very long, molecule of DNA.

    Is human body a molecule?

    So we know that the cells of the body are made up of molecules. Molecules are collections of atoms. Water is made up of oxygen and hydrogen atoms. Proteins are made of carbon, hydrogen, oxygen, and other elements.
