The discovery of cellulose.

definition

It is the “main polysaccharide in living plants, forming the skeletal structure of the plant cell wall”[1] with the formula C6H10O5. It is used in the manufacture of paper and textiles[1].

DISCOVERY

The French chemist Anselme Payen discovered cellulose in 1838. In his 1838 publication[2] he wrote about dissolving ligneous (of or resembling wood) matter in nitric acid, potash and various other solvents and obtaining a precipitate which he thought “fills the cells and which constitutes the true ligneous matter”. Payen also determined the chemical formula of this newfound substance and noted that it was the same as that of starch. Here is a photograph[3] of pure cellulose:

  1. Once I originally commented I clicked the -Notify me when new feedback are added- checkbox and now each time a comment is added I get 4 emails with the same comment. Is there any way you possibly can remove me from that service? Thanks!

    1. Hey! Could you check the end of the emails, I believe there should be an option to unsusbcribe from the notifications. Let us know if that works!

  2. The subsequent time I learn a weblog, I hope that it doesnt disappoint me as a lot as this one. I imply, I do know it was my option to read, but I actually thought youd have something fascinating to say. All I hear is a bunch of whining about something that you could repair in the event you werent too busy on the lookout for attention.
