Polysaccharides or glycans Homopolysaccharides Heteropolysaccharides D-Glucose in Nature The most abundant carbohydrate is D-glucose. Cells of organisms oxidize glucose for energy: In animals excess glucose is converted to a polymer called glycogen. Disaccharides On hydrolysis give two molecules of monosaccharides E.g Sucrose (Cane sugar) Lactose (milk sugar) Maltose (malt sugar) Polysaccharides Starch‚ cellulose‚ glycogen On the hydrolysis of

Investigating the Ratio Between Poly-Vinyl Alcohol and Sodium Borate to form a Bouncing Ball Timothy English Gen. Chem. 1 Lab Section: 009 Introduction: Poly-Vinyl Alcohol (PVA) is a water-soluble synthetic polymer that will be used as one element to form the well know bouncing ball‚ along with Sodium Borate (borax)‚ which has a variety of uses because of its weak base. PVA is ideal for this experiment because it is odorless‚ nontoxic‚ has high tensile strength and flexibility. The

colloidal system consists of two separate phases: a dispersed phase (or internal phase) and a continuous phase (or dispersion medium). A colloidal system may be solid‚ liquid‚ or gaseous. Many familiar substances are colloids‚ as shown in the chart below. As well as these naturally occurring colloids‚ modern chemical process industries utilize high shear mixing technology to create novel colloids. The dispersed-phase particles have a diameter of between approximately 5 and 200 nanometers.[2] Such

‘The Secret of Kells’’ was the wild card in the recent Oscar animation race — the little Irish movie no one had heard of‚ let alone seen. Call it luck or a brilliant promotional strategy‚ but the movie opens at the Kendall today with local animaniacs primed to happily pounce. As well they should‚ for “Kells’’ is a visually overwhelming labor of love‚ a hand-drawn medieval adventure tale that seeks and finds cosmic connections. Yes‚ you can still bring the kids. The hero of “Kells’’ is Brendan

thermoplastic polymers are mixed to produce efficient composites. Natural fibers including wood‚ kenaf‚ coir‚ pineapple‚ rice starch and etc. are used to combine with the polymers. Addition of fibers in the materials will affect the mechanical‚ thermal and water absorbent properties. Although‚ many researchers experimented with different types of organic materials‚ there have been a few studies on water hyacinth and its fibers.
