Sucrase Enzyme Localized to Taste Cells (IMAGE) Monell Chemical Senses Center Caption Taste cells, identified by presence of T1R (green), also contain the disaccaridase enzyme sucrase (red), which cleaves sucrose into the simple sugars glucose and fructose, which can be detected by both sugar-sensing pathways. Sucrase is preferentially localized in the apical tip of the taste cell, where it can act on sugars from ingested foods. Credit Karen Yee, Monell Center Usage Restrictions Credit required.
