Cellulose Molecules Made Microfibrils Describe Structure Fiber Consist

Cellulose fibers are composed of microfibrils (~80 cellulose molecules each) forming macrofibrils, held together by hydrogen bonds between cellulose molecules made of beta-glucose monomers.

Las fibras de celulosa están compuestas por microfibrillas (cada una con ~80 moléculas de celulosa) que forman macrofibrillas, unidas por enlaces de hidrógeno entre las moléculas de celulosa compuestas por monómeros de beta-glucosa.

Front Describe the structure of a cellulose fiber.
Back Cellulose fibers:
  • They consist of macrofibrils of cellulose which are made up of many microfibrils
  • Microfibrils contain about 80 cellulose molecules
  • Cellulose molecules have hydrogen bonds between them because they are parallel
  • Cellulose molecules themselves are made up of beta glucose monomers
