Binding pockets and functional outcomes of Phytochemical-Protein Interactions.

Target protein	Binding pocket characteristics	Eugenol	3-Allyl-6-methoxyphenol	Caryophyllene	Phenol, 2-methoxy-4-(2-propenyl)	3-Allyl-6-methoxyphenyl acetate	Bis(2-ethylhexyl) phthalate
Cytochrome P450	Hydrophobic cleft with heme coordination	Blocks catalytic site (potential inhibitor)	Moderate inhibition	Strong hydrophobic interference	Competitive inhibition	Weak binding, minimal effect	Steric hindrance, substrate exclusion
Ecdysone 20-monooxygenase isoform X1	Steroid-binding hydrophobic pocket	Disrupts substrate binding	Partial inhibition	Strong allosteric modulation	Competitive inhibition	Weak binding, no effect	Competitive inhibition
Muscle calcium channel subunit alpha-1	Voltage-sensing domain (hydrophobic)	Weak allosteric modulation	Channel blocking	Strong allosteric inhibition	Stabilizes inactive state	Minimal modulation	Blocks ion conduction
Odorant binding protein 2	Aromatic/hydrophobic ligand-binding site	Competitive binding (odor masking)	Weak displacement of native ligands	Irreversible binding (odor suppression)	Competitive binding	No significant effect	Strong competitive binding
Gamma-aminobutyric acid receptor subunit beta	Extracellular ligand-binding domain	Weak antagonism	Minimal modulation	Allosteric inhibition	Weak binding	No effect	Weak antagonism
Vitellogenin domain-containing protein	Lipid-binding pocket	Disrupts protein-lipid interactions	Weak binding	Strong lipid displacement	Alters structural stability	No significant effect	Competes with endogenous lipids
Gustatory receptor	Bitter-taste receptor pocket (hydrophobic)	Taste modulation	Partial agonist	Strong antagonism (taste suppression)	Competitive binding	Weak interaction	Irreversible binding
