The -ose words (glucose, sucrose, lactose, fructose) end in /oʊs/, matching the final sound of cellulose, but they do not rhyme with it because the stress falls on the earlier syllables. Celluloid and cellulite look like cellulose at the start, but their endings sound different: /lɔɪd/ and /laɪt/, not /loʊs/.
