IPA: //pɪˈreɪnoʊs//
KK: /pɪˈreɪnoʊs/
A type of sugar molecule that has a six-sided ring structure, formed from a simple sugar when it reacts with itself.
Glucose can exist in a pyranose form, which is important for its biological functions.
Pyranose is formed from "pyran" (from Greek "purus", meaning fire) and "-ose" (a suffix used in chemistry to denote sugars). The term refers to a type of sugar that has a six-membered ring structure resembling that of pyran, which is related to the concept of fire due to its cyclic nature.
Think of 'pyran' relating to 'fire' and the '-ose' indicating a sugar; this helps you remember that 'pyranose' is a sugar with a structure reminiscent of a fire-like ring.
