carbohydrates

HideShow resource information

carbohydrates are made from carbon, hydrogen and oxygen, they store energy. Plant cell wall depend on the structual role of some carbohydrates.

Types of carbohydrates:

  • monosaccharides- 1 molecule
  • disaccharides- 2 molecule
  • polysaccharides- many molecules

THEY ARE ORGANIC BECAUSE THEY CONTAIN CARBON!!

monosaccharides- small organice molecules, building blocks for more complex carbohydrates.

disaccharides- form when 2 monosaccharides units join forming a glycosidic bond by a condensation reaction.

GLUCOSE+GLUCOSE=MALTOSE

GLUCOSE+GALACTOSE=LACTOSE

GLUCOSE+FRUCTOSE=SUCROSE

GLUCOSE- C6H12O6

ALPHA GLUCOSE- CH2OH

BETA GLUCOSE- CH2OH 

when 2 molecules of glucose react a maltose molecule is made and H2O is released. This is called a condensation reaction.

POLYSACCHARIDES:

polysaccharides form from many monomers joined by glycosidic bonds.

STARCH is a polysaccharide. its a polymer of glucose, its found in plants, its an insoluble type of carbohydrate.

plants store glucose as starch so it doesnt affect the osmotic balance of the…
