The determined parameters for the examined phospholipids: DPPC and DPPE.

Interfacial Tension Values at pI γmax (N/m)	Isoelectric Point (pI) Values	Acid–Base Constant Values [21,24]		Surface Energy [J/mol]
		pKX	pKY
DPPS [23]
2.9 × 10−3	3.80	3.36	9.55	1824
DPPC
3.5 × 10−3	4.14	2.58	5.69	1800
DPPE
4.0 × 10−3	4.20	2.42	5.98	1854

where DPPC = phosphatidylcholine; DPPE = phosphatidylethanolamine; DPPS = phosphatidylserine.
