The Main Components of Macromolecules Carbon Makes Organic Molecules Why Carbon Carbon is the second most abundant element in living organisms Carbon can share four electrons, therefore it can bond to four additional atoms Carbon establishes covalent bonds (stable, high energy bonds)
Full Answer
Why is carbon so important? Carbon is life’s fundamental building stone. This is why carbon dating is reliable and carbon is found in all living things. Also, since nearly all molecules in the body contain carbon, carbon is so essential to life.

Macro-molecules are incredibly important to the human body. They are composed of a large number of atoms. Every single cell in the body is made up of marco-molecules.
1 Characteristics. ... 2 Importance of Carbon: Carbon is important for all the known living systems, and life could not exist without it. ... 3 Physical and Biological role: Carbon dioxide (CO2) a form of carbon is an essential element present in the air and in the water for sustaining life on earth.
The fundamental component for all of these macromolecules is carbon. The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
Carbon's molecular structure gives it the ability to form stable bonds with other elements, including itself, which makes it the central element of organic compounds. It makes up almost 20% of the weight of an organism, and it is essential for them to live, to grow, and to reproduce.
Why is carbon so important in biology? It bonds to only a few other elements. It has very little electronegativity, making it a good electron donor. It is a common element on Earth.
The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds. Carbon skeletons can vary in length, branching, and ring structure.
The bonding properties of carbon Perhaps more important, however, is carbon's capacity for covalent bonding. Because a C atom can form covalent bonds to as many as four other atoms, it's well suited to form the basic skeleton, or “backbone,” of a macromolecule.
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.
Carbon can bond to four other atoms which makes it so there is a wide variety of molecules that it can make. Carbon has the most potential to make large, complex and varied molecules. It can make proteins, DNA, carbohydrates and other molecules that distinguish living matter from inanimate material.
The unique properties of carbon make it a central part of biological molecules. Carbon binds to oxygen, hydrogen, and nitrogen covalently to form the many molecules important for cellular function. Carbon has four electrons in its outermost shell and can form four bonds.
Carbon is important for all the known living systems, and life could not exist without it. Carbon is available in the form of hydrocarbons other than food and wood such as fossil fuel, methane gas, and crude oil. Carbon fibres have multiple uses since they are strong, yet lightweight, durable material. These fibres are used in making tennis rackets, fishing rods, even aeroplane, and rockets. The industrial diamonds are used for drilling and cutting rocks.
Carbon has a high melting point and can easily combine with oxygen at elevated temperatures. It acts as an excellent hardener for iron and yields the various steel alloys.
When Carbon atoms are bonded together in different ways, they are called as allotropes of carbon. Some best-known allotropes are diamond, graphite, and amorphous carbon. Graphite is one of the softest known substances and diamond is the hardest substance. Its physical properties may vary from the allotropic form.
Photosynthesis by green plants takes their energy from the sun in order to break down water into oxygen and hydrogen. The living organisms who cannot photosynthesis are bounds to rely on other living organisms in order to consume their minimum requirements of carbon dioxide molecules. Thus, a balance of carbon and oxygen is necessary for the survival of almost all living organisms on this planet.
Also, since nearly all molecules in the body contain carbon, carbon is so essential to life. Carbon can bind to, and to other carbon molecules, four other groups around it.
The formation of the carbon atomic nucleus happens by the triple-alpha mechanism within a giant or supergiant star. In the interiors of stars on the horizontal branch, carbon is created, according to the latest theory of physical cosmology. As big stars die like a supernova, carbon is dispersed like ashes into space.
Carbon has a high melting point and can easily combine with oxygen at elevated temperatures.
They are composed of a large number of atoms. Every single cell in the body is made up of marco-molecules. When we consume food, we intake the large biological molecules found in the food.
Such molecules can be termed as carbohydrates, proteins, lipids (fats) and nucleic acids. They are required for energy, structure, DNA, enzymes, etc. Carbohydrates are the primary source of energy, starch and glycogen and ribose for our body.
The Nucleic Acid codes your genetics and is the blue prints from where the proteins are produced. Proteins perform all the functions including moving the molecules and derive their shape, send signals to the neighbouring cells and replicate DNA.
Lipids are the phospholipids on of the most important things in your body that makes up the Phospholipid bilayer that surrounds the cell. Some lipids act as major structural components of cell membranes. In all, each macro-molecule serves a variety of functions or roles that are very crucial for the proper functioning of the body.
Proteins are made up of Amino acids and make up your cell organelles and enzymes. While proteins can be regarded as the energy resources, they are also recommended for their nitrogen which is necessary to build new proteins and Nucleic Acid.
Fat in the brain surrounds neurons and facilitate the easy flow of electric signals. These are excellent energy storage molecules and can be stored for years. But it should be noted that all fats are not same and can be harmful for the body. These may be the saturated or the trans-fats.
