Sheet Of Cellulose Nitrate Sheet Of Cellulose Polymers
571 wordsPolymers have been around longer than we have. In fact, polymers are as old as life itself, as all life on earth is based on three types of polymers, namely DNA, RNA, and proteins. But this report is about some of the earliest synthetic polymers, that is, polymers made by humans, specifically, the cellulose derivatives. The very first synthetic polymer was of course leather, a modified natural polymer, an artificially crosslinked form of the proteins found in animal skins. Leather tanning was di...

Support For Large Segments Support For Large Polymers
922 wordsBiodegradable polymer sutures Biodegradation: A biological agent (an enzyme, microbe or cell) responsible for degradation. Most degradable polymers are polyesters. Polymers prepared from glycolic acid and lactic acid have found a multitude of uses in the medical industry, beginning with the biodegradable sutures first approved in the 1960 s. Since that time, diverse products based on lactic and glycolic acid and on other materials, including poly (dioxanone), poly (trim ethylene carbonate) copol...

Sugar Molecules Linked Aldehyde Or Ketone Group Monosaccharides
387 wordsThere are three principal kinds of carbohydrates and each are classified according to the number of sugar molecules they contain. Monosaccharides, such as ribose, glucose, and fructose, contain only one sugar molecule. Disaccharides consist of two sugar molecules linked covalently. Familiar examples are sucrose (table sugar), maltose (malt sugar), and lactose (milk sugar). Polysaccharides, such as cellulose and starch, contain many sugar molecules linked together. Monosaccharides are organic com...

Fatty Acids Important Part
603 wordsCarbohydrates and lipids / fats are a very important part of our lives. They have many similarities and differences among each other, which distinguish them from other macromolecules. Carbohydrates, which include sugar and their polymers, are used by organisms for fuel and building material. They come in many various forms going from simplicity to complexity. The simplest, monosaccharides, compose of single sugars whose parts are arranged around asymmetric carbons. They generally have a molecula...

Institute Of Technology Nobel Prize
1,224 wordsMaterial science is the study of the properties of solid materials and how those properties are determined by a material s composition and structure. Most engineers have the primary function of relating the design and production of machinery and components. Materials science and engineers are involved with all aspects of engineering and provide the best material for a large variety of applications. In the workplace materials science and engineers can specify, test, and qualify the materials used...

Liquid Crystal Natural Polymers Polymer
415 wordsPolymers are large molecules composed of smaller molecules called monomers. Monomers are produced and either grow together or are assembled to produce a single polymer. There are synthetic and natural polymers. Some examples of natural polymers would be wood, starches, fingernails, and hair. Synthetic polymers are usually referred to as plastics. Petroleum, is the primary monomer used to produce polymers. An English chemist named Alexander Parkes was the first scientist to produce the first synt...

Plastics Are Made Kind Of Monomer Plastic
628 wordsPlastics are Plastic 2 PLASTICS Plastics are man-made materials that can be shaped into almost any form. They are one of the most useful materials ever created. Our homes, schools, and businesses are filled with plastic products. Imagine cars without synthetic bumpers, dashboards, steering wheels and switches; medicine without plastic hypodermic syringes and artificial hip joints. And what about telecommunications, dependent on plastic telephones, circuit boards and cable insulation. Our enterta...

Due To The Fact Hydrogen Bonds
1,126 wordsProperties of Cellulose Cellulose is a complex carbohydrate, or polysaccharide consisting of 3, 000 or more glucose units. The basic structural component of plant cell walls, cellulose comprises about 33 percent of all vegetable matter (90 percent of cotton and 50 percent of wood are cellulose) and is the most abundant of all naturally occurring organic compounds A natural polymer made up from D-glucose (C 6 H 12 O 6) monomer units, cellulose contains glucose units which link together to form lo...
