How does cellulose chain grow?

How does cellulose chain grows in a terminal complex, where polymerization and crystallization take place simultaneously. Which chain ends, reducing or non-reducing ones, does UDP-G link to ? Does hydrolytic enzyme have selectivity toward the chain polarity or not? To answer such problems, we established a combined chain-end visualization technique together with electron diffraction. The directionality on cellulose and chitin synthesis as well as biodegradation of some enzymes have been reported.
