Energy and entropy at play in competitive dissociations: The case of uneven positional dissociation of ionized triacylglycerides

Highlight
- We have explored the competing dissociation of TAG-NH4+ adduct ions.
- Competition between sn-1,3 and sn-2 position bond cleavage due to energy and entropy effects.
- Sn1,3 fatty acid cleavage is energetically favourable.
- Sn2 fatty acid cleavage is entropically favoured.
