Answer :

  • A substance is considered to be organic if its molecules contain C and often at least one C-C or C-H link. Very small carbon-containing molecules, such as (text CO 2) and simple carbonates, that do not adhere to the aforementioned guidelines are regarded as inorganic. Without carbon, there would be no way to support life on Earth. The majority of living cell molecules, with the exception of water, are carbon-based and are referred to as organic compounds. Carbohydrates, lipids, proteins, and nucleic acids are the main groups of organic molecules that we shall examine in this section.
  • Each of these kinds of chemicals is made up of big molecules assembled from little pieces. Monomers are the smallest of these constituent parts. Polymers are created when several monomers bind together. Due to the chemical connections produced, each of these polymers has a unique structure that defines it. The function of the chemical in living organisms is connected to these structures. Consequently, we shall examine each class of compounds under the following headings:
  • The primary components of the compound class's molecular structure.
  • structural composition: the way in which the monomers combine to form polymers.
  • The biological significance of these compounds for both plants and animals.
  • Chemical testing: how to look for each type of component.
