求翻译：这是因为蛋白质处于等电点时，具有一些特殊的理化性质,此时不仅是它的阴、阳离子性质向相反方向转化的转折点,而且在此特定情况下,其导电率、渗透压、黏度以及溶解度等性质均达最低值是什么意思？

This is because at the isoelectric point of the protein , with some special physical and chemical properties , only this time it 's overcast , cationic nature of the transformation of a turning point in the opposite direction , and in this particular case , its electrical conductivity, osmotic press

This is because protein is in point, with a number of special chemical nature, in this case is not only the female, male-ION nature in opposite direction into the turning point, but, in this particular case, the conductivity, osmometer, viscosity and solubility, and nature are to reach the minimum v

This is because the protein is in time the isoelectric point, has some special physics and chemistry nature, not only this time is it cloudy, the positive ion nature the turning point which transforms to the reverse direction, moreover in this specific situation, its nature and so on conductivity, o

This is because proteins in the isoelectric point, has some special physical and chemical properties of anions and cations in nature are not the only turning point in the opposite direction, and in this particular case, its electrical conductivity and osmotic pressure below the minimum values for pr
