Morphology
pyranose = pyran (opaque) = pyran + ose
Though analyzable as pyran + -ose within chemistry, the elements are technical and not accessible to an average B1 learner, so the meaning cannot be derived from common vocabulary.
Etymology
Pyranose comes from the ring name pyran, meaning a 'six-atom ring' that includes one oxygen, plus the ending -ose, which means 'sugar' as in glucose. So a pyranose is a sugar that takes the form of a 'six-atom ring' with one oxygen atom.
