Marvelous milk

1 Dec

Cow suckling her calf

Most of my news articles don’t have a back story. But my most recent chemistry story combined food, molecules, animals. . .  and a little bit of family.

Dairy runs in my family. My grandfather ran a small dairy for more than 30 years, in and around his day job. My father has worked in dairy science, as a university professor, but mostly working in Extension, working with dairy farmers and tools that keep track of milk data and production. My uncle, a large animal veterinarian, does embryo transfers in cattle.

So, when an editor approaches me with a milk story, I’m game.

Though I knew that milk provides a way for moms to provide antibodies to babies, I’m intrigued by the possibility that there are a mixture of enzymes that may both activate milk proteins within the stomach and then shield them from being shredded into amino acids. This chemical and biological marvel mixes fats, proteins, and sugars and even whole cells. Researchers now have a pretty good picture of what’s in there, but plenty of work remains to figure out how it all works together.
