An enzyme that converts cellulose into glucose or a disaccharide.
‘A good digestive enzyme should include lipase to digests fats, amylase for carbohydrates, protease for proteins, cellulase for cellulose and fiber, and lactase for dairy.’
‘As is erodes, it releases the digestive enzymes, amylase, lipase, and cellulase.’
‘As such, it's an abundant source of energy, but most animals lack the enzyme cellulase, which breaks the bonds that lock the individual sugar molecules together.’
‘In the discussion, Kimball Atwood proposed that it might be possible to put the enzyme cellulase into humans, so that people could consume paper.’
‘They did not yield isoprimeverose; additionally, charophyte material was not digestible with xyloglucan-specific endoglucanase or cellulase to give xyloglucan-derived oligosaccharides.’
