| Soluble acid invertase and alkaline invertase were assayed as described previously with some modifications. |
| Grape sugar is mainly composed of glucose and fructose, produced after sucrose hydrolysis by invertase during grapevine maturation. |
| The procedure is based on the cleavage of sucrose by invertase to glucose and fructose. |
| Cold sweetening so far has been attributed to soluble, vacuolar invertase rather than to cell-wall-bound invertase. |
| Enzymes shown are invertase, sucrose synthase, cytosolic AGPase, and plastidic AGPase. |
| Following sucrose cleavage by invertase, the liberated glucose and fructose are phosphorylated before undergoing further metabolism. |
