The effort to sequence the human genome, and subsequently to make the results publicly available, has created a new paradigm in the biological sciences. Now that we have access to the blueprint of our very structure and those of organisms from viruses to plants to animals, a mechanistic understanding of all the processes involved in our growth and metabolism is possible. Characterization of the genetic differences among us is underway, and should provide the information basis for a new approach …

Fig. 1—Milk is a good example of a food the synthesis and digestion of which are naturally bioguided. A mechanistic understanding of these pathways should improve the processing of milk and other products.

Fig. 3—Milk fat globular membrane. This material was recovered by ultrafiltration and supercritical extraction of the aqueous phase which results from butter production.
