Why bog acids react differently with bones of the bodies than they do with the organs and hair?

Bog acids, primarily humic and fulvic acids, have a stronger affinity for organic compounds found in soft tissues, such as organs and hair, which are more susceptible to decomposition. Bones, composed mainly of collagen and minerals like hydroxyapatite, are less reactive with these acids, allowing them to preserve longer in acidic environments. Consequently, while the soft tissues can break down and dissolve in the presence of bog acids, the mineral-rich structure of bones remains largely intact, leading to different rates of decay and preservation. This differential reaction is key to understanding the preservation of ancient remains in bog environments.
