Baker carbohydrate week 5 test 2 Flashcards
Aldoses and Ketoses of
triose
A: Glycerose or glyceraldehyde
K:dihydroxy acetone
Aldoses and Ketoses of
tetrose
A: erythrose
K:erthrulose
Aldoses and Ketoses of
pentose
A: ribose, xylose, arabinose
K: Ribulose, xyluose
Aldoses and Ketoses of
Hexose
A:glucose, galactose
K: Fructose
Isometric forms of fructose
fructofuranose and fructopyranose
**furctofuranose is more stable
what is the only non reducing sugar
sucrose
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.
what are the three main polysaccharides
cellulose, starch, and glycogen
cellulose
have beta 1-4 bonds that humans cannot digest
startch
made of amylose which is alpha 1-4 and linear and amylopectin which is alpha 1-6 every 50 residues
what is unique about chitin
it alternates alpha 1-4 and beta 1-4 every other residue
N- and O- glycosylation
form the backbone of complex carbohydrates
what is a glycoprotein
a protein with oligosaccharide chains covalently attached to their polypeptide side chain
usually short
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
Glycosaminoglycans examples
hyaluronate
chondroitin
keratan sulfate
heparin
