‘Green’ composites using cellulose fibers as reinforcement promise a sustainable and renewable alternative to petroleum-based plastics. But how green are these composites? Koon-Yang Lee, at Imperial College London, and colleagues at University College London led by Paola Lettieri have quantified the ...
macromolecule.A giant molecule formed by the joining of smaller molecules, usually by a condensation reaction. Polysaccharides, proteins, and nucleic acids are examples of this type of molecule. What does macromolecule mean in biology? Meaning. Biological macromolecule.A large, organic molecule suchas ...
For derived aquaculture sub-products, the most efficient process is recovering important biomolecules such as proteins (collagen, gelatine), polysaccharides (chitosan), lipids (omega 3) or pigments (astaxanthin or beta-carotene). Biomolecules can further be applied for human and animal consumption, ...
but they remain pretty much unchanged. But if you add right amount of warm water, the starch granules swell, break down and release some of their contents into the water. In other words, theygelatinize. You can get a similar affect by mixing starch with cool water and heating it to its...
More complicated examples of the shear rate formula relate shear rate to other properties of liquids such as flow velocity, porosity, permeability and adsorption. This lets you use shear rate in complicated biological mechanisms, such as the production of biopolymers and other polysaccharides....
Seaweed structural polysaccharides are similar to terrestrial plant polysaccharides and primarily consist of celluloses, hemicelluloses, xylans, and mannans, whereas storage polysaccharides, such as carrageenan, alginate, and agar, are more specific to seaweed species and are the most commercially ...
