Twig Walkingstick: Guinea pigs and vitamin C

Dear Twig: The food I buy for my guinea pigs (Clover, Smiley) has vitamin C added to it. The food I buy for my hamsters (Kramer, Mrs. Kramer) doesn't. Why?

Guinea pigs, those cute, li'l squeakers, can't make their own vitamin C. Hamsters (cute, littler, not nearly as squeaky) and most other mammals can. Guinea pigs, instead, must get all their vitamin C from their food. If they don't get enough--"Ah! Squeak squeak squeak!"--they sicken and die from scurvy. So that's why vitamin C is put in guinea pig food sold in pet stores.

Why can't squeakers make their own C? It has to do with an enzyme that their bodies don't produce. Called L-gulono-gamma-lactone oxidase, or GULO, it's essential to the process that produces vitamin C. Most other mammals have GULO. Know what others don't? Hint: You're one of them! Yes, humans and other primates (apes, chimps, etc.) lack GULO and so can't make their own vitamin C.

Have an orange, friend!


P.S. Vitamin C, also called ascorbic acid, is in many fruits and vegetables besides oranges.
