Monosaccharides Little hexagon/pentagon things
Basics • Contain: • Carbon • Hydrogen • Oxygen • Nothing Else
Shimple Shtuff A Little Bonding Session • Carbon does 4 bonds • Nitrogen does 3 bonds • Oxygen does 2 bonds • Hydrogen does 1 bond
Make me, you know you want to! Trioses • Three carbon sugars • This one is called: glyceraldehyde • Aldehyde means this part:
Hexoses • Six Carbon Sugars. • Glucose • Fructose • Galactose • Can be straight chain or, more often than not, in a ring
Glucose • Straight chain: Make it again, Sam
Glucose • Ring form: • Two versions: Alpha and Beta
Drawing Glucose • Has been a question in an exam! • Alpha=DUDD Beta=DUDU (spot the irony). Make it as we go along!
Ribose and Deoxyribose • Found in RNA and DNA. • Yes, you are supposed to know about them. Not their structures though, so it’s not all bad!
SWEET! Monosaccharides • All the sugars we’ve looked at have had the same basic formula. • Have you spotted the pattern?! • Complete: CnH?O? • All monosaccharides are: Soluble and…
