Be aware that when FLA batteries are in a partially discharged state for any length of time, or if the electrolyte dips low enough to expose the plates to air, sulfation will occur rapidly, insulating the plates against the required chemical reactions.
"Sulfation is one of the top causes of lead-acid battery failure," affirms Mack Trucks Director of Product Strategy Roy Horton.

On an evolutionary basis, it has been proposed that galactans in marine organisms occur regarding preferential sulfation site based on a tendency toward 2-sulfation for animals, 4-sulfation for algae and marine angiosperms, and in the case of 6-sulfation, as a dispersive distribution among phyla during evolution (Pomin & Mourao, 2008).
They discuss the mechanisms of the sulfation reaction, emphasize what is known about sulfur capture in FBC boilers, and briefly cover the topic of sorbent reactivation.
Sulfation of DHEA increases the solubility of the steroid so that it can be readily excreted renally.
This is called sulfation and results in the loss of active material needed to generate electrical energy.
Because post-translational modifications such as sulfation and glycosylation require co-substrates that contain high-energy phosphate bonds, the biosynthesis of post-translationally modified peptides requires considerably more energy than the biosynthesis of other peptides.
CSPG sulfation can also influence plasticity [65-67] and protease-dependent PNN processing [68].
However, IL-32 can bind to the RGD motif of integrin, and IL-32 isoforms contain predicted tyrosine sulfation sites, which are prevalent in secreted proteins [2, 5, 59].
Heparin undergoes extensive sulfation and rarely phosphorylation or carboxylation during synthesis and hence is a highly negatively charged biological molecule [32].
