  2. Cellulose - Wikipedia

    en.wikipedia.org/wiki/Cellulose

    Cellulose is the most abundant organic polymer on Earth. [6] The cellulose content of cotton fibre is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. [7] [8] [9] Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and ...

  3. Biopolymer - Wikipedia

    en.wikipedia.org/wiki/Biopolymer

    Hydrophilic polymers are not water resistant and allow water to get through the packaging which can affect the contents of the package. Polyglycolic acid (PGA) is a biopolymer that has great barrier characteristics and is now being used to correct the barrier obstacles from PLA and starch.

  4. Polymer chemistry - Wikipedia

    en.wikipedia.org/wiki/Polymer_chemistry

    Polymers can be classified in many ways. Polymers, strictly speaking, comprise most solid matter: minerals (i.e. most of the Earth's crust) are largely polymers, metals are 3-d polymers, organisms, living and dead, are composed largely of polymers and water. Often polymers are classified according to their origin: biopolymers; synthetic polymers

  5. Lignocellulosic biomass - Wikipedia

    en.wikipedia.org/wiki/Lignocellulosic_biomass

    It is the most abundantly available raw material on the Earth for the production of biofuels. [1] It is composed of two kinds of carbohydrate polymers, cellulose and hemicellulose, and an aromatic-rich polymer called lignin. [1] Any biomass rich in cellulose, hemicelluloses, and lignin are commonly referred to as lignocellulosic biomass. [2]

  6. Polysaccharide - Wikipedia

    en.wikipedia.org/wiki/Polysaccharide

    Cellulose is used in the cell walls of plants and other organisms and is said to be the most abundant organic molecule on Earth. [6] It has many uses such as a significant role in the paper and textile industries and is used as a feedstock for the production of rayon (via the viscose process), cellulose acetate, celluloid, and nitrocellulose.

  7. Chitin - Wikipedia

    en.wikipedia.org/wiki/Chitin

    Chitin is the second most abundant polysaccharide in nature (behind only cellulose); an estimated 1 billion tons of chitin are produced each year in the biosphere. [1] It is a primary component of cell walls in fungi (especially filamentous and mushroom-forming fungi), the exoskeletons of arthropods such as crustaceans and insects, the radulae ...

    Hydrogen is the most abundant element to the universe—it's actually element number one—and the atomic weight is 1.008, so 10/08 is designated National Hydrogen and Fuel Cell day, because many ...

  9. Biomolecule - Wikipedia

    en.wikipedia.org/wiki/Biomolecule

    After cellulose, lignin is the second most abundant biopolymer and is one of the primary structural components of most plants. It contains subunits derived from p -coumaryl alcohol , coniferyl alcohol , and sinapyl alcohol , [ 15 ] and is unusual among biomolecules in that it is racemic .
