Metabolism of 4-hydroxybenzaldehyde, 3-bromo-4-hydroxybenzaldehyde and bromide by cell-free fractions of the marine red alga Odonthalia floccosa

Cell-free fractions from Odonthalia floccosa incubated with 4-hydroxybenzaldehyde-[U-14C], 3-bromo-4-hydroxybenzaldehyde-[U-14C] and 82Br− formed the dibromo-dihydroxybenzaldehyde derivatives of the bromophenols (brominated benzylalcohols) which were also identified as naturally occurring products.
