U1B CARBOHYDRATES

structure and function of carbohydrates

define monosaccharides

• simple carb

• monomers

• when joined together make complex carbohydrate

what is glucose

glucose is a hexose sugar (6 carbon atoms)

it is also a carbohydrate

what is an isomer

chemicals with the same formula but different structure

structure of a alpha glucose

• down

• down

• up

• down

structure of an beta glucose

• up

• down

• up

• down

what are the differences between B/A glucose

• alpha is less stable and more reactive its used by plants to make starch

• beta glucose is more stable and less reactive used by plants to build cellulose

Name 3 key monosaccharides

• Galactose

• Fructose

• Ribose and Deoxyribose

what is the structure of Galactose

• up

• down

• up

• up

info about Galactose

• another isomer of glucose

• same chemical formula but different arrangement of atoms

• very similar properties to glucose

info about fructose

• another isomer of glucose

• found in almost all fruits

• cane sugar, sugar beets and corn

• very sweet

info about Ribose

• important component of RNA and ATP

• essential for cell growth, cell division and energy production
