Abstract
A novel hydrophobic vitamin B.sub.12 derivative represented by the formula: ##STR1## wherein R represents an alkyl group having 2 to 17 carbon atoms, and X represents a cyano group, a hydroxyl group, an alkyl group or a 5'-deoxyadenosyl group. Since the derivative is hydrophobic, it can be taken up by an organism by thermodynamic diffusion, a passive transport, without an active transport.
