Carbon

Carbon dating. Carbon dating As we all know that on Earth, life is based on carbon. Carbon dating is a technique that uses the decay of Carbon−14 to estimate the age of organic materials, such as wood and leather, up to about 58,000 to 62,000 years. The dating method is based on the fact that carbon is found in various forms. Understanding the importance of carbon and its versatility makes one to think and explore about such type of applications.

Learning Objectives

After completing the topic, the student will be able to:

  • Explore why carbon is considered as the backbone of all biological molecules.
  • Discover and understand why Organic chemistry is a part of our lives at every moment.
  • Examine the versatility of carbon atom.
  • Evaluate the tendency of carbon atom to form multiple bonds.
  • Understand how carbon atoms can form diverse molecules by bonding to four other atoms.
  • Identify the molecular diversity arising from carbon skeleton.
  • Analyze and explore how functional groups affect a carbon molecules' chemical reactivity.
  • Define the term ATP and appreciate the importance of it as a source of energy for cellular processes.
Carbon forms the backbone of biology Carbon forms the backbone of biology for most of life on Earth Carbon forms the key component for all known naturally occurring life on Earth. Complex molecules are made up of carbon bonded with other elements, especially oxygen, hydrogen and nitrogen.
Carbon

Carbon forms the backbone of biology for most of life on Earth. Complex molecules are made up of carbon bonded with other elements, especially oxygen, hydrogen and nitrogen, and carbon is able to bond with all of these because of its four valence electrons.

Carbon is abundant on earth. It is also light weight and the atom is relatively small in size, making it easier for enzymes to manipulate carbon molecules. It is often assumed in astrobiology that if life exists somewhere else in the universe, it will also be carbon based.

Life is based on carbon's ability to form diverse structures and an endless number of different carbon–based molecules. The study of carbon–containing compounds has come to be known as Organic Chemistry. The food that we intake, the fragrances we inhale, the colors we see are predominantly due to organic compounds.

Life is based on carbon Life is based on carbon All life forms require certain core chemical elements needed for biochemical functioning. These include carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur − the elemental macronutrients for all organisms. The most biologically abundant of these elements is carbon, which has the desirable attribute of forming multiple, stable covalent bonds. This allows carbon-based (organic) molecules to form an immense variety of chemical arrangements.
Carbon-based life

Organic chemistry is a part of our lives at every moment. Organic molecules comprise the tissue of plants as mighty as the redwoods, convey signals from one neuron to the next in animals, store the genetic information of life, and are the food we eat each day. The growth of living things from microbes to elephants rests on organic reactions, and organic reactions provide the energy that drives our muscles and our thought processes.

Our lives depend on organic chemistry in many other ways as well. Every article of clothing we wear is a product of organic chemistry, whether the fibers are natural or synthetic. Hardly a minute goes by when we’re not using something made of organic molecules, such as a pen, a computer keyboard, a music player, or a cellular phone. We view display screens made of organic liquid crystal arrays. Natural organic polymers comprise wood and the paper we read. Natural and synthetic organic molecules enhance our health. There is not a single aspect of our lives that is not in some way dependent on organic chemistry. But what is organic chemistry? Organic chemistry is the chemistry of compounds that contain the element carbon. Clearly, carbon compounds are central to life on this planet. Carbon as an element, however, has its origin elsewhere.
