Natural products are chemicals produced by living organisms. They are divided into primary and secondary metabolites. Primary metabolites are directly involved in growth, while secondary metabolites are not essential for growth but improve survivability. Natural products can be extracted from entire organisms, parts of organisms, or bodily fluids. They are categorized based on their origin as biotic materials, bio-based materials, bodily fluid materials, or natural materials. Chemistry of natural products describes their structures and properties. Natural products are synthesized through semi-synthesis or total synthesis.
