生理酸性盐（physiologically acid salt）

　　 指植物根系在某种盐溶液中，对其阳离子吸收的量大于阴离子时，造成溶液 pH值下降，则称该盐为生理酸性盐。例如，将植物培养在硫酸钾（ K2 SO4 ）溶液中，由于植物对钾的需要量大于对硫的需要量，因此，根系吸收 K 量较 SO2- 4 为多。为保持体内电性平衡，根细胞向外界分泌质子（ H ），使溶液中 H 增加， pH值下降。这是由于根系生理活动的结果，由此而得名。  

Synthesis of Polyampholyte Comb-Type Copolymers Consisting of a Poly(L-lysine) Backbone and Hyaluronic Acid Side Chains for DNA Carrier

Polycations have been used as nonviral gene carriers because the polycations and DNAs form stable complexes in a noncovalent manner (1 –3 ). The polycations, e.g., poly(L-lysine) (PLL), are reported to be conjugated with several ligands
