Description:

A photo collage showing two different structures of fructose molecules, along with their common sources (honey and corn syrup).

A ball and stick model of β-D-fructofuranose structure (found in corn syrup) shown next to sweet corn, along with a ball and stick model of β-D-fructopyranose structure (found in honey) shown next to a honeybee and flower.
Caption:
Would sugar by any other name taste as sweet? We learn in lecture 12 that the fructose in honey is a pyranose, whereas the fructose in corn syrup is a furanose, and one actually is sweeter. (Collage by MIT OpenCourseWare. Images by Benjah-bmm27, Severnjc, & USDA. Wikimedia Commons, public domain.)
