Ramchandran plots are used to assess the possible conformations of secondary structural elements in peptides.

The C-N bond length of a peptide is longer than that found in methyl amine (CH3-NH2).

An increase in dissociation constant (Kd) implies a decrease in the binding affinity of a protein to its ligand.

The side chain of Lys (pKR =10.5) will be positively charged at pH:

Buffers work best when their pH values are equal to the pKa values of their weak acids.

Cation exchange resins contain positive charges.

All non-polar amino acids (with their pK1 and pK2 being 2.5 and 9.5, respectively) exist in “zwitterionic forms” at one of following pH values:

The microbes which inhabit extreme environmental conditions are known as:

The dispersed benzene molecules in water tend to aggregate together due to:

If the pH of a solution is 6.0, what will be the concentration of its hydroxide ion?
