A biomolecule is a chemical compound that naturally occurs in living organisms. Biomolecules consist primarily of carbon and hydrogen, along with nitrogen, oxygen, phosphorus and sulfur.

Molecules that are synthesized and metabolized by living cells or organisms, e.g. macromolecules like proteins, nucleic acids (DNA and RNA), and carbohydrates, as well as their building blocks and degradation products. Combinatorial Chemistry Method in chemistry which creates and analyzes a large number of similar molecules ("Combinatorial Libraries"). Used e.g. in drug development to find the most effective compounds from a substance group. Deoxyribonucleic acid (DNA) The molecule that encodes genetic information. DNA is composed of a sequence of four different basic molecules called nucleotides. The nucleotides are symbolized by the letters A, C, G, and T. In nature, a DNA molecule consists of two DNA strands which are connected by weak bonds and form a double helical structure (resembling a drilled rope ladder). Both strands have complementary sequences, as interactions are only formed between A and T and between C and G. Edman Sequencing A chemical method, developed by P. Edman in 1950, for complete elucidation of the primary structure (amino acid sequence) of proteins. During this procedure, the individual amino acids are split off and analyzed one after the other.

There is no good term for proteins and nucleic acids taken together, so that's what I use the term biomolecule for.
