Vitamin

Cobamamide (AdoCbl), which is also known as adenosylcobalamin and dibencozide, is, along with methylcobalamin (MeCbl), one of the active forms of vitamin B₁₂.

Dimethylglycine (DMG) is a derivative of the amino acid glycine found in beans and liver. It can be formed from trimethylglycine upon the loss of one of its methyl groups. It is also a byproduct of the metabolism of choline.

Folic acid (also known as vitamin B9 or folacin) and folate (the naturally occurring form), as well as pteroyl-L-glutamic acid and pteroyl-L-glutamate, are forms of the water-soluble vitamin B9. Folic acid is itself not biologically active with its biological importance being due to tetrahydrofolate and other derivatives after its conversion to dihydrofolic acid in the liver.
