Carbohydrate Chemistry Flashcards
Monosaccharide
Simple sugar. Contains multiple chiral centres.
What suffix indicates carbohydrates?
“ose”
How do we classify monosaccharides?
Aldoses: contain aldehyde group
Ketoses: contain ketone group
How are aldoses and ketoses classified?
By the number of carbons they contain. Insert (tri, tetr, pent, hex, hept) immediately before the suffix “ose”
i.e., Aldopentose, Ketohexose
Importance of carbohydrates?
Energy storage and production: glycogen.
Functional & Recognition: glyolispids, glycoproteins on cell surfaces (blood group determinants, protein-protein binding, protein-nucleic acid interactions etc)
Structural: Chitin, Cellulose, Hyaluronic acid (in connective and nervous tissue)
Structural role of carbohydrates?
Hyaluronic acid, cellulose, chitin
