My group studies the organic compounds known as natural products or secondary/specialzied metabolites by biologists.

Natural products are often called biomolecules by some fields. However, I think this can be argued to be incorrect. In fact; the strange tendency to stick bio- on anything remotely extracted from sources such as crops, plants or bacteria is a very strange one to me; since items like acetic acid have been obtained from plants from a very long time.

For clarity: 

The terms "organic compound" and "biomolecule" are used frequently in chemistry, particularly in the fields of organic chemistry and biochemistry, and they have distinct meanings:

1. Organic Compound: An organic compound is generally any chemical compound that contains carbon-hydrogen bonds. The field of organic chemistry studies a wide range of organic compounds, which include not only naturally occurring compounds but also man-made substances like plastics, synthetic drugs, and petrochemicals. The defining feature of these compounds is the presence of carbon, often bonded with elements like hydrogen, oxygen, nitrogen, sulfur, and phosphorus. Organic compounds can be simple (like methane) or incredibly complex (like DNA), and they are not necessarily associated with living organisms.

2. Biomolecule: Biomolecules, on the other hand, are a subset of organic compounds that are produced by living organisms and are essential for life. They are involved in the structure, function, and regulation of the body's cells, tissues, and organs. Biomolecules include carbohydrates, lipids, proteins, and nucleic acids. These molecules are crucial for various biological processes and are typically studied in the field of biochemistry. Biomolecules are distinguished not just by their chemical structure but also by their role in biological systems.

In summary, while all biomolecules are organic compounds, not all organic compounds are biomolecules. Biomolecules are a specific category of organic compounds that are essential for life (nucleotides, proteins etc) and are produced by living organisms. Natural products are not essential for life but are niche specific.
