Question

Which of the compounds found in wood are difficult to degrade (or break apart)? (select all that apply.)?

Answer 1

There are four major components found in wood, and these are:

cellulose

starch

protein

Among the four, I believe that cellulose and lignin are the most difficult to degrade because they contain large amount of cross-linked heavy hydrocarbons.

Answer:

cellulose

lignin
