19138732-1	2009	The diffusion mechanism of vitamin B12 in two types of crosslinked hydrogels, poly(acrylic acid) (cPAA) and copolymers of acrylic acid and N-vinyl pyrrolidinone (cP(AA-NVP)) was studied.	copolymers	108-118	NADH:ubiquinone oxidoreductase subunit B3	Homo sapiens	35-38	
19138732-3	2009	In the copolymers permeability of B12 is controlled by both intramolecular and intermolecular hydrogen-bonding between the pyrrolidinone and carboxylic acid side chains.	copolymers	7-17	NADH:ubiquinone oxidoreductase subunit B3	Homo sapiens	34-37
