Intermediate filaments are uniquely non-polar and built by lateral bundling in five steps: 1. synthesis of an alpha-helical monomer
2. formation of a coiled-coil dimer
3. formation of a staggered tetramer of two coiled-coil dimers
4. lateral association of 8 tetramers
5. addition of 8 tetramers to a growing filament.

At what step is polarity lost?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

How do you interpret a chromatogram for what mixtures contain?

A1.50-liter sample of dry air in a cylinder exerts a pressure of 3.00 atmospheres at a temperature of 25°c. without changing the temperature, a piston is moved in the cylinder until the pressure in the cylinder is reduced to 1.00 atmospheres. the volume of the gas is
