  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. 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.

  5. 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 .

  6. Polymer - Wikipedia

    en.wikipedia.org/wiki/Polymer

    Polymer nomenclature is generally based upon the type of monomer residues comprising the polymer. A polymer which contains only a single type of repeat unit is known as a homopolymer, while a polymer containing two or more types of repeat units is known as a copolymer. [22] A terpolymer is a copolymer which contains three types of repeat units ...

  7. Water distribution on Earth - Wikipedia

    en.wikipedia.org/wiki/Water_distribution_on_Earth

    Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.

    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. Xylan - Wikipedia

    en.wikipedia.org/wiki/Xylan

    Xylans are polysaccharides made up of β-1,4-linked xylose (a pentose sugar) residues with side branches of α-arabinofuranose and/or α-glucuronic acids.On the basis of substituted groups xylan can be categorized into three classes i) glucuronoxylan (GX) ii) neutral arabinoxylan (AX) and iii) glucuronoarabinoxylan (GAX).
