Lactose is a disaccharide made of a glucose and a galactose bonded together. Lactose is found in milk yet does not taste sweet because our taste receptors do not sense lactose. Our taste receptors do sense galactose and glucose. How can a mug of warm milk taste sweet, without adding sugar? [Select the best answer.] The activation energy required for the hydrolysis of lactose into glucose and galactose is supplied by heating the milk. The milk proteins are denatured by the heat. The reaction is endergonic so the heat is the energy required for the reaction to occur. The lactose has less free energy than the glucose and galactose.

Cysteine proteases are enzymes that degrade proteins. You may have heard of some examples of these types of proteins before! Bromelain is an enzyme found in pineapple that is commonly used as a meat tenderizer and is the reason Jell-O with fresh pineapple will not solidify. Cysteine proteases are remarkably similar to serine proteases (like chymotrypsin), except they have a cysteine in their active site rather than a serine. Using the mechanism that we discussed for serine proteases, draw a corresponding mechanism for a cysteine protease cleaving the bond between an alanine-glycine dipeptide. Note that cysteine proteases do not require an aspartate in their active site. Also note that the cysteine is usually in its thiolate form (deprotonated) and the histidine is in its imidazolium form (fully protonated) in the resting state of the enzyme.
