What is the origin of biomolecules?

Answer 1

Biomolecules, such as proteins, nucleic acids, carbohydrates, and lipids, are believed to have originated on early Earth through a combination of chemical processes. The primordial soup hypothesis suggests that simple organic compounds formed in the oceans via reactions driven by sunlight, volcanic activity, and lightning. These compounds eventually polymerized into more complex molecules, leading to the first living organisms. Additionally, some theories propose that biomolecules may have originated from extraterrestrial sources, such as meteorites containing organic compounds.
