The Molecules of Life Part 1: carbohydrates

The Molecules of Life Part 1 The molecules associated with living things are grouped into four major categories: Carbohydrates Lipids (Fats) Proteins Nucleic Acids

Carbohydrates contain carbon, hydrogen and oxygen in a 1: 2: 1 ratio. The basic building blocks of carbohydrates are monosaccharides (simple sugars). Each monosaccharide has at least 2 hydroxyl groups and an aldehyde or ketone group.

Glucose (C 6 H 12 O 6) is an example of a monosaccharide. ∗ carbon, hydrogen and oxygen in a 1: 2: 1 ratio

Carbohydrates contain carbon, hydrogen and oxygen in a 1: 2: 1 ratio. The basic building blocks of carbohydrates are monosaccharides (simple sugars). Each monosaccharide has at least 2 hydroxyl groups and an aldehyde or ketone group. Glucose is an example of a monosaccharide. Oligosaccharides are sugars that contain a few simple sugar units linked together by covalent bonds. These bonds are formed when hydroxyl groups on adjacent sugars react to produce a molecule of water and link the sugars through a shared oxygen atom. Reactions that build larger molecules from smaller units, while producing water are called condensation synthesis reactions.

Sucrose is an example of an oligosaccharide made up of a glucose and a fructose. glucose fructose

Sucrose is an example of an oligosaccharide made up of a glucose and a fructose. glucose fructose (water is produced) (sugars are linked through a shared oxygen atom) sucrose

Sucrose is an example of an oligosaccharide made up of a glucose and a fructose. Let’s see that again (Nelson Biology 12 animation)

Carbohydrates http: //www. ars. usda. gov/is/kids/weirdscience/story 4/orang ejuice. jpg Monosaccharides and oligosaccharides are used for quick energy. Polysaccharides are formed when dozens, hundreds or thousands of simple sugar units are linked. These molecules are used for energy storage (e. g. starch) or structural components (e. g. cellulose). http: //www. champsmushrooms. ca/champs/images/m ushroom_carton. gif http: //agnews. tamu. edu/dailynews/st ories/SOIL/photos/May 2002 a. jpg http: //www. kohlmaierfarm. com/potatoes. jpg http: //www. hort. purdue. edu/ext/senior/ http: //www. internet-grocer. net/bread. jpg vegetabl/images/large/celery. jpg http: //www. fell 2 earth. com/puzzles/rope. jpg
