K: Fructose

5

Isometric forms of fructose

fructofuranose and fructopyranose
**furctofuranose is more stable

6

what is the only non reducing sugar

sucrose

7

what is an anomeic carbon

a carbon that has for different atoms attached to it.
they are reducing if they have a free OH bound to it.

8

what are the three main polysaccharides

cellulose, starch, and glycogen

9

cellulose

have beta 1-4 bonds that humans cannot digest

10

startch

made of amylose which is alpha 1-4 and linear and amylopectin which is alpha 1-6 every 50 residues

11

what is unique about chitin

it alternates alpha 1-4 and beta 1-4 every other residue

12

N- and O- glycosylation

form the backbone of complex carbohydrates

13

what is a glycoprotein

a protein with oligosaccharide chains covalently attached to their polypeptide side chain
usually short

14

what is a proteoglycan

a subclass of glycoproteins that consist of a protein core with one or more covalently attached glycosaminoglycan chains
usually long chains

15

Glycosaminoglycans examples

hyaluronate
chondroitin
keratan sulfate
heparin

16

What is the important carbohydrate in saliva

mucin
