Rap sheet

Answers to
Collagen: Greek for “glue maker.”
Height
9.4 nm as drawn: a short lab-made stand-in. The real one is 300 nm.
Weight
About 500 zeptograms, full length.
Build
Three strands twisted into a rope. Every third link is glycine.
Habits
Holds you together. A third of all the protein in your body.
Marks
Boiled, it unwinds into gelatin. Cooled, the strands rewind and the dessert sets.
Weakness
As gelatin, melts below body temperature. Fresh pineapple chews it up.
Last seen
