biogéniques

Biogéniques refers to substances or processes that originate from living organisms. This term is often used in scientific contexts, particularly in biology, chemistry, and geology, to distinguish natural, biologically produced materials from those that are synthetic or inorganic. For instance, biogenic sediments are those composed wholly or partly of the hard parts of dead organisms, such as shells, coral skeletons, or plant matter.

In the field of medicine and pharmacology, biogenic amines are a group of naturally occurring compounds derived from amino acids. Examples include neurotransmitters like serotonin and dopamine, as well as hormones. These molecules play crucial roles in various physiological functions.

The study of biogenic materials is important for understanding ecological cycles, the formation of natural resources, and the functioning of biological systems. It also has implications for fields like paleontology, where identifying biogenic fossils helps reconstruct past environments and life forms. The term emphasizes the biological origin and nature of the substance or process, highlighting its connection to life.
