A protein biochemist attempted to determine the amino acid sequence of a decapeptide. Use the results from the trypsin, chymotrypsin, and cyanogen bromide treatments to suggest the amino acid sequence of this decapeptide.
unused lead nitrate to the container marked"sodium nitrate". What could the student do to get all the led ions out from the sodium nitrate?
If a molecule is more affected by London Dispersion forces that means it will have a higher melting point. if big molecules are less affected by dipole-dipole attractions, they will have a higher melting point. are these statements true?
