Definition |
For an organic geochemist, biomarkers are compounds found in geosphere that have retained enough structural or chemical information to be related to a single or a group of source organisms.
Hopane, specific to bacteria, is a biomarker. Sterane, specific to eukaryote, is a biomarker. Isorenieratene derivatives are biomarkers and derive from the brown strain of the green sulfur bacteria Chlorobiaceae. |
