Other claims from this paper (12)
- Method / resource The molar distribution of A and B chains enabled estimation of chains per cluster.
- Observation Cereal amylopectins had more chains per cluster than root and tuber amylopectins.
- Observation C chains appeared to include long and short forms connecting two clusters and occurring in a single cluster, respectively.
- Observation Amylopectin comprised three molecular species.
- Observation The large amylopectin species was major by mole and weight.
- Observation Medium and small amylopectin species were relatively large by mole but very small by weight.
- Observation Three amylopectin species appeared to have similar cluster structure and different numbers of clusters.
- Observation The large and medium species may be granule blocklets and small species immature or degraded products.
- Observation Amylose comprised multiple molecular species of different sizes whose proportions differed by plant source.
- Observation Small amylose species predominated in cereals.
- Observation Large amylose species predominated in root and tuber sources.
- Method / resource Labeling/HPSEC estimates agreed with conventional colorimetric estimates.
