Put ethanol or methanol into peptides solution, the peptides will precipitate or not？
Homework Answers
This entirely depends on the amino acid composition of the peptide.
Peptide containing polar or charged side chain can hydrogen bond with the methanol or ethanol leading to dissolution and peptide-solvent interaction.
If there are a number of hydrophobic amino acids are present, this may lead to unfavourable interaction in methanol and ethanol leading to precipitation.
So, all peptides will not precipitate in methanol or ethanol.

5. Ethanol and methanol are form an ideal solution at 20 °C. Vapor pressure of pure ethanol and pure methanol at 20 °C is 44.5 and 88.7 mmHg, respectively. If 100 g of ethanol and 100 g of methanol are mixed into a solution, calculate: (a) the mol fractions of ethanol and methanol in the solution, (b) the partial pressures of ethanol and methanol and total pressure of the solution, and (c) the mol fraction of methanol in a vapor...

An unknown alcohol is analyzed by freezing point depression. The unknown is either methanol (CH3OH), ethanol (C2H5OH), or propanol, (C3H7OH). A solution made by adding 10.423 g of the unknown to 100.0mL of water freezes at -4.2 degrees C [water kFP= -1.853 degrees C.kg/mol, assume d(water)= 1g/mL]. Explain how you used the data to identify the alcohol.
