Example Sentences

Within the tunnel, Cel7A chops up cellulose -- which has repeating units of glucose -- into two-sugar cellobiose fragments.

From Science Daily

"We aren't exactly sure how the enzyme threads the glucose chain to the tunnel or what exactly goes on inside, but we knew from previous studies that the product that comes out the back door, cellobiose, can interfere with the processing of subsequent cellulose molecules. Now, we know more about how it is interfering."

From Science Daily

The researchers found that cellobiose in solution can bind to the "back door" of the tunnel, which can slow down the exit of subsequent cellobiose molecules as it essentially blocks the way.

From Science Daily

"Because cellobiose is so similar to cellulose, it's maybe not surprising that the little pieces can get into the tunnel," Hancock said.

From Science Daily

Although strategies exist to remove components like xylan and lignin from the cellulose, the researchers said the removal of cellobiose is more difficult.
