Investigations on cellulose formation in cotton seeds

Summary

In cottonseed-hairs a structural polysaccharide is formed very early. According to DC, IR and X-ray investigation it represents an amorphous cellulose containing a tightly bound protein fraction. Starting with about the 20th day of maturing, crystalline cellulose of constant degree of polymerization is formed, which still contains a constant, though very small fraction of protein, which may be regarded as a residue of the synthesis-apparatus.

Zusammenfassung

Bei Baumwoll-Samenhaaren wird schon sehr frühzeitig ein Strukturpolysaccharid gebildet, das nach DC, IR und Röntgenuntersuchungen eine amorphe Cellulose darstellt und eine fest gebundene Proteinkomponente enthält. Etwa vom 20. Reifetag an wird kristalline Cellulose von konstantem Polymerisationsgrad gebildet, die immer noch einen konstanten, wenngleich geringen Proteinanteil enthält, der möglicherweise den Rest des Syntheseapparates darstellt.
