Oleuropeinic acid is present initially in olive tissues or formed by the thermal treatment, possibly by the oxidation of oleuropein. Oleuropeinic acid is an antioxidant-soluble fiber.

Guaiacylglycerol-beta-guaiacyl Ether is degraded by microorganisms and is commonly used as a substrate to mimic microbial degradation of cell walls of lignin-living plants.

Amyloid β-Protein (1-12) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.
