The is because both are hydrophobic (due to their neutral
side chains) and have approximately the same net charge. The isoelectric point
of leucine at 25 degrees centigrade is 6.04 while that of alanine is 6.11. Therefore,
this mutation does not change the
structure of the protein hence does not affect its function (if not considerably).
