However, the PEG concentration increasing causes a surface tension reduction, which indicates increasing the surface-active component amount on the interface.
This process is facilitated by sperm surface proteins and leads to specific binding of the sperm surface-active component with the egg zona pellucida and, ultimately, sperm-egg fusion [ 21].
Saturated phosphatidylcholine largely consists of dipalmitoylphosphatidylcholine (DPPC), which accounts for approximately 40% of total lipids and is the major surface-active component.
The kinetics of the phase separation process into bulk phases is also modified by the presence of surface active components.
PC, especially the disaturated dipalmitoyl species (PC16:0/16:0), is the major surface active component of surfactant phospholipid.
This might be partly due to adsorption of surface-active urine components (resistant to washing) at the electrode surface.
Alkaline and/or ammonium alkylarylsulfonates (n-dodecylbenzenesulfonates) (Figure 3A), anionic surface-active compounds, are traditional components of the active substance in many washing/food sanitizing receipts.
After loading the Z-N catalyst, the active components anchor on the surface and internal pores of the supports.
TiO2 is an inert support which mainly provides the dispersing surface for the active component, by loading a certain amount of active substances on the mesoporous TiO2, the catalytic performance could be potentially improved.
The terpene trilactones, bilobalide and ginkgolide A, B, C, M and J are, besides the flavonoids, the pharmacologically active components of the G. biloba leaves.
In this recording configuration, cortical neurons are only active during the surface-positive component of the slow oscillation.
