Table 4. Branch structure of glycogen and starch.
| Glucan source | β-Amylolysis (%)a | ECLb | A∶B ratioc |
| WT | 48±2 | 6.6 | 1.1∶1.0 |
| M1 | 40±3 | 5.5 | 1.0∶1.0 |
| M2 | 45±5 | 5.8 | 0.9∶1.0 |
| Rabbit-liver glycogen | 32±1 | 5.6 | 1.1∶1.0 |
| Waxy maize starch | 55±1 | 12.3 | 1.6∶1.0 |
a
Values given were determined from at least two duplications.
b
ECL (exterior chain length) = CL (which is equal to DPn in Table 3)×β-amylolysis (%)+2.0.
c
The ratio was calculated based on the mole fraction of (G2+G3) stubs released, by isoamylase and pullulanase hydrolysis, from β-limit dextrin.
