Biodegradable polymers can degrade either by hydrolysis (without the enzyme catalysis) or by enzymatic mechanism hydrolysis is the main degradation mechanism of the biodegradable polymers, but depending on the polymer structure, they can also undergo at least partial enzymatic degradation hydrolytic degradation means the breakdown of the hydrolytically unstable polymer backbone in the presence of water. The giant molecules of life together monomers of the same chemical composition or structure a polymer consisting of all the same monomer is also incorporated . They also have different functions describe how the structures of different polymers are related to their functions polymers come in many different types within biology. The polymer chain is often shown in two dimensions, but it should be noted that they have a three dimensional structure each bond is at 109° to the next and, therefore, the carbon backbone extends through space like a twisted chain of tinkertoys.

The essay question :s (aqa biology unit 5) watch announcements 10 polymers have different structures, they also have different functions describe how the . Polymers and their properties introduction basic topics: types of polymers classification of polymers characteristics of polymers properties of polymers streng. But not only do polymers fold like this polymers also form stacks of these folded chains the polymer chains will often decide they want to come back into the . Manufactured polymers can also be one-dimensional chains that can be melted the structure of polymers they do not biodegrade under other circumstances.

If two or more different type monomers are involved, the resulting copolymer can have several configurations or arrangements of the monomers along the chain the four main configurations are depicted below: figure 1: copolymer configurations polymer physical structure segments of polymer molecules can exist in two distinct physical structures. Chapter 5: structure of polymers the chemical bonds in polymers are also different than those they affect the chemical and physical properties of a polymer. Free essay: comparing the sculptures and different structures of cathedrals the cathedral was a symbol of authority and religious achievement to people of. Polymers and monomers sometimes polymers are also known as macromolecules or large-sized molecules we have two different groups of monomers because we have .

Chapter outline: polymer structures but have different atomic a single mer is sometimes also called a monomer. The polyester dacron and the polyamide nylon 66, shown here, are two examples of synthetic condensation polymers, also known as step-growth polymers in contrast to chain-growth polymers, most of which grow by carbon-carbon bond formation, step-growth polymers generally grow by carbon-heteroatom bond formation (c-o & c-n in dacron & nylon respectively). Researchers have designed a polymer material that can change its structure in response to light, converting from a rigid substance to a softer one that can heal itself when damaged you can . Polymers and plastics: an introduction preferred way of depicting polymer structures tool for tuning polymers so that they have the right combination of . They can have very different shapes, although the most common structure involves a long chain typically they are constructed from small, repeating units linked together to form this long chain these macromolecules are also called polymers polymers are made of many small molecules linked together.

Chapter 5 the structure and function of macromolecules they also function as the raw material for the synthesis of other monomers, such as amino acids and fatty . Different proteins have different shapes as the shapes are determined by the sequence of amino acids the primary stage of a protein is a polypeptide chain, the second is where the polypeptide chain forms as an alpha helix or/and a beta pleated sheet. Like ceramics, polymers have good chemical resistance, electrical and thermal insulation properties they are also brittle at low temperatures the following table provides a general comparison of the properties between the three types of materials. Structure and function of bio-molecules such molecules are different in a sense that they have a contain also non-peptide structures .

Polymer blending is a process to mix two or more different polymers to allow these three polymer structures nanopolymers are used because they have very . Manufacturing: materials and processing materials as a field is most commonly represented by ceramics, metals, and polymers while noted improvements have taken place in the area of ceramics and metals, it is the field of polymers that has experienced an explosion in progress. Their best-known use is as textile fibres, but they have many other applications a different class of polymers are the mixed organic they are also relatively . Polymers have different structures, they also have different functions describe how the structures of different polymers are related to their functions 11 describe .

Each polymer has a structure that is related to its function examiners are also given instructions as follows: if the essay contains information from more than . Chapter 2 - biology (everything) they have the same chemical formula but different structures, c6h12o6 they are different since they have a phosphate group . Basic materials often have much in common for example the nylons (or polyamides), important engineering thermoplastics, are found both in textiles and in coatings epoxies are used both in paints and in adhesives and composites the structure of the polymer materials industry is summarised in figure 12.
