How one type of atom (carbon)can be the basis of so many types of biomolecules?

Carbon is uniquely suited to serve as the basis for many types of biomolecules due to its chemical properties. Carbon atoms have the ability to form strong covalent bonds with other carbon atoms and with other elements such as hydrogen, nitrogen, oxygen, and phosphorus.
The versatility of carbon arises from its electron configuration. Carbon has four valence electrons, which means it can form up to four covalent bonds. These bonds can be single, double, or triple, and can be formed with other carbon atoms or with atoms of other elements. This ability allows carbon atoms to build long chains, branched structures, and cyclic arrangements.
Organic biomolecules, such as carbohydrates, lipids, proteins, and nucleic acids, are primarily composed of carbon atoms. For example, carbohydrates are made up of carbon, hydrogen, and oxygen atoms, with the carbon atoms forming the backbone of the molecule. Lipids are composed of carbon and hydrogen atoms, and their varied structures are created by the arrangement of these atoms. Proteins are made up of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur, with carbon forming the structural framework and participating in the various functions of proteins. Nucleic acids, like DNA and RNA, consist of carbon, hydrogen, oxygen, nitrogen, and phosphorus atoms, with carbon forming the backbone of the nucleotide units.
The ability of carbon to form a wide variety of bonds and arrangements allows for the immense diversity of biomolecules. By changing the number, order, and types of atoms attached to the carbon backbone, the properties and functions of biomolecules can be drastically altered. This versatility is crucial for the complexity and diversity of life.
