Dear Beverly,
	Many enzymes (in fact nearly all) denature when heated to > 37 C.  If
your reaction to this is "Well, duh!  What do you take me for?", then you
probably didn't overheat the test tube.  Other conditions, such as pH, ionic
strength and presence of possible cofactors or inhibitors also affect enzyme
reactions, but Benedict's solution probably takes all that into account.  If
not, see if there was anything amiss in the reaction mixture.  Your teacher
may also be right (It *has* been known to happen.).  Good luck.
				Yours,
				Bill Tivol
