Interacting selectively with DNA (deoxyribonucleic acid) [goid 3677] [pmid 16405401] [evidence IDA]; Interacting selectively with fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis [goid 5504] [pmid 16289007] [evidence IDA]; Interacting selectively with fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis [goid 5504] [pmid 9731778] [evidence NAS]; Interacting selectively with fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis [goid 5504] [pmid 16413837] [evidence IDA]; Interacting selectively with copper (Cu) ions [goid 5507] [pmid 14726550] [evidence NAS]; Interacting selectively with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules) [goid 5515] [pmid 16099937] [evidence IPI]; Interacting selectively with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease [goid 8144] [pmid 10940303] [evidence NAS]; Interacting selectively with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease [goid 8144] [pmid 16169013] [evidence IDA]; Interacting selectively with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease [goid 8144] [pmid 16307046] [evidence IDA]; Interacting selectively with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease [goid 8144] [pmid 16413740] [evidence IDA]; Interacting selectively with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease [goid 8144] [pmid 16413734] [evidence IDA]; Interacting selectively with a toxin, a poisonous substance that causes damage to biological systems. Toxins are differentiated from simple chemical poisons and vegetable alkaloids by their high molecular weight and antigenicity (they elicit an antibody response) [goid 15643] [pmid 16169013] [evidence IDA]; Inhibition of the reactions brought about by dioxygen (O2) or peroxides. Usually the antioxidant is effective because it can itself be more easily oxidized than the substance protected. The term is often applied to components that can trap free radicals, thereby breaking the chain reaction that normally leads to extensive biological damage [goid 16209] [pmid 14726550] [evidence NAS]; Interacting selectively with oxygen (O2) [goid 19825] [pmid 16283771] [evidence IDA]; Interacting selectively with pyridoxal 5' phosphate, 3-hydroxy-5-(hydroxymethyl)-2-methyl4-pyridine carboxaldehyde 5' phosphate, the biologically active form of vitamin B6 [goid 30170] [pmid 16201370] [evidence IDA]; Interacting selectively with any metal ion [goid 46872] [evidence IEA]
