Chemical and Physical Properties Of Water

Extracts from this document...

Introduction

BIOLOGICAL SCIENCES Chemical and Physical Properties Of Water Water is the most abundant material on the earth's surface, typically forming between 70 - 95% of cell mass. It's molecules have an imbalance of charge (they are dipolar) and so this generates the hydrogen bonding between them. ...read more.

Cell Membranes Cell membranes control what enters and leaves a cell, as well as keeping the cell contents together. Much of the membrane is made up of a 'sea' of phospholipids with protein molecules 'floating' in between the phospholipids, the phospholipids are usually arranged in two layers. ...read more.

Conclusion

Has the formula C6H12O6. Glucose and fructose are simple sugars and are isomers, same number of C H O atoms but arranged differently. Fructose has a different shape to glucose and the different shape means it has different properties. Disaccharides - these form when a condensation reaction joins two monosaccharides. 2 glucose molecules form maltose and two fructose molecules form sucrose. Polysaccharides - are giant molecules such as glycogen and cellulose, formed when many single sugars undergo condensation reactions. ...read more.
