Another mixture comprising 27% of a phosphate lipid, 43 mol % of an imino lipid and 30 mol % of a neutral lipid has a charge ratio or C/A of 43/54=0.8 due to the double nominal charge of the phosphate group.It becomes apparent from the definition and examples, that molar ratios or...
2) the cationic charge prevails at pH 4, and 3) the anionic charge prevails at pH 8.As a result the substance or mixture of substances has an isoelectric point of neutral net charge between pH 4 and pH 8. Amphoteric character is by this definition different from zwitterionic character, as...
