Can Palmitic Acid be derived from humic and fulvic acid?  Explain if
possible, or point to an article(s) in literature that would reveal
the answer(s).

Palmitic acid can not be derived from either fulvic or humic acid.
Palmitic acid is a so-called saturated fatty acid and can be derived
from vegetable oils, like palm oil. It consists of a straight (linear)
chain of 16 carbon atoms.



Fulvic and humic acid are complex multi-cyclic structures, present in
e.g. guano and soil. There is no chemical relationship between these
two and palmaitic acid.
