Comparisons between the structure and function of collagen and insulin.

Extracts from this document...

Introduction

Comparisons between the structure and function of collagen and Insulin Insulin is a very important hormone and is also it is a fibrous protein, this means its properties are that it is extensible, strong and insoluble it is also a secondary structure which is made up of ? helices and � sheets, where as collagen is a important structural protein found in animals which is a globular protein (a secondary structure bent and folded into spherical shapes) which is soluble which consists of a hydrophobic core which is surrounded by a hydrophilic external surface. ...read more.

Middle

The structure of insulin is a compact cylinder with the carboxyl of polypeptide chain B longer then the rest of the protein. Insulin contains many hydrophobic residues which together form a hydrophobic core where as a collagen molecule is a much larger structure, it consists of three polypeptide chains which each contain around 1000 amino acids which are coiled together to form a triple helix. The collagen polypeptide contains nearly one-third glycine, every third amino acid is glycine, and all the other amino acids are mostly either proline or hydroxyproline. ...read more.

Conclusion

insulin is that mainly increases the rate of synthesis of fatty acids, protein and glycogen, and also inhibits the breakdown of protein and glycogen. A very important part of the process is to stimulate cells such as liver, muscle and fat to remove glucose which causes an overall reduction of blood glucose levels, some other sugars and amino acids are also removed from the blood, which are either used or stored as fat or glycogen. In insulin in your body is not functioning or you are not sensitive it you will form diabetes where as if collagen is not functioning then you may form brittle bone disease. ...read more.

  1. Identification of amino acids by chromatography.

    The charged substances move towards the opposite end and the negligibly charged substances are separated by forming ionic bonds with ions present in the solution. The charge of the protein molecule depends on the amino acid composition and the pH of the solution and so can be separated by charge.

  2. Structure and Functions of Collagen and Insulin.

    Insulin stimulates many metabolic reactions following receptor binding: * stimulates glucose transport * stimulates amino acid transport * increases glycogen synthase activity * increases the rate of general protein synthesis * depresses lipolysis and protein degradation * Insulin is catabolized primarily in the liver and kidney.

  1. Investigating the Rate of the Reaction between Bromide and Bromate Ions in Acid Solution

    When I varied the catalyst: Catalyst Repeat 1 Repeat 2 Repeat 3 Repeat 4 Repeat 5 Time/s Temp/K Time/s Temp/K Time/s Temp/K Time/s Temp/K Time/s Temp/K Mn2+ 313 294.5 298 295.5 202 295 308 295 (Table 4.3.3) These results are so different from the other results that they suggest something serious went wrong.

  2. How does the primary sequence of a protein dictate its structure and function?

    There are three main steps. In initiation (far left) all of the necessary parts of the process are brought together by a small molecule called a ribosome. During elongation, amino acids, the building blocks of proteins, are joined to one another in a long chain.
