Bioengineering and Application of Novel Glucose Polymers
Abstract
Glucan phosphorylase, branching enzyme, and 4-α-glucanotransferase were employed to produce glucose polymers with controlled molecular size and structures. Linear or branched glucan was produced from glucose-1-phosphate by glucan phosphorylase alone or together with bracnhing enzyme, where the molecular weight of linear glucan was strictly controlled by the glucose-1-phosphate/primer molar ratio, and the branching pattern by the relative branching enzyme/glucan phosphorylase activity ratio. Cyclic glucans were produced by the cyclization reaction of 5-αglucanotransferases and branching enzyme on amylose and amylopectin. Molecular size and structure of cyclic glucan was controlled by the type of enyzyme and substrate chosen and by the reaction conditions. This in vitro approach can be used to manufacture novel glucose polymers with applicable value.

Emerging modified carbohydrates offer metabolic and energy efficiency advantages by regulating the use of substrates during exercise.
“These emerging modified carbohydrates not only offer metabolic and energy efficiency advantages (by regulating the use of substrates during exercise) but may also benefit certain species of microorganisms in the gut of athletes by acting as a source of non-digestible fiber [90].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
