  2. Palmitic acid - Wikipedia

    en.wikipedia.org/wiki/Palmitic_acid

    [9] [10] Its chemical formula is CH 3 (CH 2) 14 COOH, and its C:D ratio (the total number of carbon atoms to the number of carbon-carbon double bonds) is 16:0. It is a major component of palm oil from the fruit of Elaeis guineensis , making up to 44% of total fats. Meats, cheeses, butter, and other dairy products also contain palmitic acid ...

  3. Polymer characterization - Wikipedia

    en.wikipedia.org/wiki/Polymer_characterization

    The characterization of mechanical properties in polymers typically refers to a measure of the strength, elasticity, viscoelasticity, and anisotropy of a polymeric material. The mechanical properties of a polymer are strongly dependent upon the Van der Waals interactions of the polymer chains, and the ability of the chains to elongate and align ...

  4. Micelle - Wikipedia

    en.wikipedia.org/wiki/Micelle

    Micelle formation is essential for the absorption of fat-soluble vitamins and complicated lipids within the human body. Bile salts formed in the liver and secreted by the gall bladder allow micelles of fatty acids to form. This allows the absorption of complicated lipids (e.g., lecithin) and lipid-soluble vitamins (A, D, E, and K) within the ...

  5. Capric acid - Wikipedia

    en.wikipedia.org/wiki/Capric_acid

    Capric acid, also known as decanoic acid or decylic acid, is a saturated fatty acid, medium-chain fatty acid (MCFA), and carboxylic acid.Its formula is CH 3 (CH 2) 8 COOH. Salts and esters of decanoic acid are called caprates or decanoates.

  6. Fatty acid - Wikipedia

    en.wikipedia.org/wiki/Fatty_acid

    Saturated fatty acids have perfectly straight chain structure. Unsaturated ones are typically bent, unless they have a trans configuration. In chemistry , particularly in biochemistry , a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated .

  7. Polymer chemistry - Wikipedia

    en.wikipedia.org/wiki/Polymer_chemistry

    Thus, the measured viscosity of polymers can provide valuable information about the average length of the polymer, the progress of reactions, and in what ways the polymer branches. [11] Composites are formed by combining polymeric materials to form an overall structure with properties that differ from the sum of the individual components.

  8. Necking (engineering) - Wikipedia

    en.wikipedia.org/wiki/Necking_(engineering)

    The amount of strain in the stable neck is called the natural draw ratio [6] because it is determined by the material's hardening characteristics, not the amount of drawing imposed on the material. Ductile polymers often exhibit stable necks because molecular orientation provides a mechanism for hardening that predominates at large strains. [7]

  9. PHBV - Wikipedia

    en.wikipedia.org/wiki/PHBV

    The monomers, 3-hydroxybutanoic acid and 3-hydroxypentanoic acid, are joined by ester bonds; the back bone of the polymer is made up of carbon and oxygen atoms. The property of the PHBV depends upon the ratio of these two monomers in it. 3-hydroxybutanoic acid provides stiffness while 3-hydroxypentanoic acid promotes flexibility.
