Thiamin and B₆ are converted into their active forms by the addition of a phosphate group. Thiamin is converted into thiamin pyrophosphate (TPP), while B₆ is converted into its active form, pyridoxal-5-phosphate (PLP). These conversions enable the vitamins to carry out their essential roles as coenzymes in various metabolic reactions.
