Lactose is a sugar like glucose or fructose and so cannot be denatured as can enzymes, which are proteins. However, if you heat lactose long enough it will caramelize (oxidize), like the sugar in sweetened condensed milk does when super heated.
Heating lactose-free milk does denature the enzyme it contains to digest lactose, lactase, and inhibit it from working further.
Lactose intolerance is when a person has difficulty or is unable to digest milk sugars from dairy products. It is rare for Caucasians to develop lactose intolerance. The condition is more common among Australian Aborigines and people from Asia, Africa, the Middle East and some Mediterranean countries. Symptoms include bloating, gas, abdominal pain and diarrhoea. Many babies are wrongly assumed to have lactose intolerance.
