what chemical properties make carbon such an important biological molecule?
531721
The unique properties of carbon make it a central part of biological molecules. With four valence electrons, carbon can covalently bond to oxygen, hydrogen, and nitrogen to form the many molecules important for cellular function. Carbon and hydrogen can form either hydrocarbon chains or rings.

Organic compounds are those who chemical formula contains at least one carbon atom, and often contain a hydrogen atom as well. The bonds formed between the carbon and hydrogen atoms to form a hydrocarbon are very strong, and the resulting compound is often essential to living things.
1042736
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds.

Organic molecules in organisms are generally larger and more complex than inorganic molecules. Their carbon skeletons are held together by covalent bonds. They form the cells of an organism and perform the chemical reactions that facilitate life.

In living systems, large organic molecules, called macromolecules, can consist of hundreds or thousands of atoms. Most macromolecules are polymers, molecules that consist of a single unit (monomer) repeated many times. Four of carbon's six electrons are available to form bonds with other atoms.

There are four categories of organic molecules: Carbohydrates, lipids, proteins and nucleic acids. All of the organic molecules are based on which element? Organic molecules have four common characteristics. First, they are all carbon based, meaning they all contain carbon.
475929
Carbohydrates, lipids, proteins and vitamins have carbon in their structure, making them organic. Water and minerals do not, so they are inorganic.

Organic Compounds Carbon has the ability to form very long chains of interconnecting C-C bonds. This property allows carbon to form the backbone of organic compounds, carbon-containing compounds, which are the basis of all known organic life. Nearly 10 million carbon-containing organic compounds are known.

organic molecule. A molecule of the kind normally found in living systems. Organic molecules are usually composed of carbon atoms in rings or long chains, to which are attached other atoms of such elements as hydrogen, oxygen, and nitrogen.

Organic molecules can include things like carbohydrates, proteins, and fats. While organic molecules can have non-carbon atoms contained inside them, like oxygen, nitrogen, or even iron, they are mostly made of carbon and hydrogen chains. ... Inorganic molecules do not contain carbon-hydrogen bonds.

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.

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

Organic molecules contain carbon and hydrogen, tend to be larger, have covalent bonds, and are non-electrolytes. Inorganic molecules consist of any substance that can't be classified as organic.
