Observations on carbon compounds in everyday use

Answer»

Earth's living organisms, INCLUDING humans, are OFTEN referred to as carbon-based life forms. This means our bodies and the plants and animals around us contain carbon compounds such as sugars, starches and proteins. In addition, there are many carbon compounds in everyday use around the house, in our cars and outside. Carbon is very versatile and is part of many of the molecules that make up objects we use constantly. Add the FACT that we exhale carbon dioxide, which is in the air everywhere, and it becomes obvious that carbon is a very important element for life.In addition to these organic compounds, carbon is found in the molecules making up rubber, plastics, gasoline, natural gas and mineral oil. ... Carbon USES in everyday life INCLUDE burning carbon compounds for heat or energy and eating foods containing carbon in the form of carbohydrates.
