The main structural difference between starch glycogen cellulose comes from? In: Human and Animal Interaction Starch‚ glycogen and cellulose are all polymers of glucose. They differ in the type of glucose present and the bonds which link thr glucose monomers together. Starch and glycogen are made from alpha-glucose. This is an isomer of glucose in which the hydroxyl (-OH) group attached to carbon number 1 is below the plane of the ring. Starch is itself composed of two types of polymer:amylose

fitted to equation 7. Note that prior measurements of density on poly(ethylene glycol) + water should perform to calculate the values of V_∅^∞ for the polymer. Table 3 has shown these empirical values for different molalities of poly(ethylene glycol). Some of the researchers 11‚ 18‚ 20 have proposed that the dependency of〖 V〗_∅ on the molality of the polymer is a linear function specified

muds: mud 1 (water + bentonite)‚ mud 2 (water+ bentonite + barite)‚ mud 3(water+ bentonite + barite + polymer)‚ mud 4 (water + bentonite + barite + polymer + CaCl2) in order to compare the rheological properties of each. It was observed that the density of mud 2 increased due to the adding of barite and there was an increase in the density of the muds‚ because of the adding of bentonite‚ polymer and CaCl2. All the mud behave as a Bingham plastic fluid. To conclude‚ with was observed that the components

construction nowadays have been favouring environmental friendly material in construction with the lowest cost possible‚ this section will also discuss about the benefits of each material to the environment. Glass Fibre Reinforced Polymer Glass Fibre Reinforced Polymer or GFRP is a material that can be shaped into almost any shape. The example of GFRP is shown in figure xx. This material can replace cold rolled steel as purlins or girts. If GRFP is utilized‚ the portal frame section can be design

macromolecules functions as each of them do a specific task in the body. Macromolecules are grouped into carbohydrates‚ nucleic acids‚ proteins‚ and lipids. In most cases macromolecules are polymers‚ which is a long molecule which are made by linking together a large number of small‚ similar compounds called monomers. Polymers are formed by a dehydration reaction‚ this happens by the -OH group being removed from one monomer‚ and a

Proteins and some carbohydrate are polymers. In carbohydrates‚ the monomers are monosaccharides. They contain the elements carbon‚ hydrogen and oxygen. In proteins the monomers are called amino acids. They contain carbon‚ hydrogen‚ oxygen and nitrogen. The polymers in our food are insoluble so they cannot be directly absorbed into

REPAIRS‚ REHABILITATION AND RETRO-FITTING | Significance of Ferrocement repairs | After‚ we in India‚ started manufacture of concrete in years 1930’s‚ the negative aspect of concrete started showing after sometime as below:- | - Deterioration due to poor workmanship‚ particularly high water content and corrosion of reinforcement and R.C.C. Technology being new. | - Leakages in concrete due to rain water as well as in water retaining structures | This menace become conspicuous after construction
