Abstract
In many respects, lactose is a unique disaccharide in living things. It is synthesized only in an adult, female mammal and has not been found as such in plants or lower animal forms. The ability of animals to synthesize lactose appears to be, therefore, a rather recent event in animal evolution and may have occurred some 200 million years ago as mammals evolved. Lactose synthesis is also a tissue specific reaction since it occurs only in the mammary gland, and then but for the short periods of lactation during adult life. Although it should be evident from these considerations that the synthesis of lactose must be strictly controlled, it is only recently that some insight has been obtained into its regulation. It is the purpose of this report to discuss recent developments in our knowledge of the regulation of lactose synthesis and to consider the properties of the components of the regulatory system.
