cellibiose

glucose and glucose
b

maltose

glucose and glucose
a

sucrose

glucose and fructose
a

hemiacetal

-alcohol + aldehyde

penicillin

-penicillin binds and inactivates enzymes that crosslink peptidoglycan strands
-interferes w/ cell wall synthesis

peptidoglycan layer

-N-acetylglucosamine and N-acetylmuramic acid
-pentaglycine linkages

bacterial cell wall

-need for fast osmotic changes

glycogen phosphorylase

-cleaves off glucose units from non-reducing end

pancreatic amylase

-continues digestion to maltose and maltotriose

branching

-only 1 reducing end in glycogen
-can be oxidized to free aldehyde

glucosidase

-removes one glucose at a time

amylase

-in saliva
-catalyzes random cleavages

starch

-we can eat
-composed of amylose and amylopectin
-alpha 1-4 bonds
-so we can eat it!
-accessible to hydrolytic anzymes (amylase in saliva)

chitin

-exoskeletons
-B linked

cellulose

-B linked
-structural component in plants
-glycosidic bonds

maltose

-alpha linked
-we can digest

cellibiose

-beta linked
-we can't digest

galacans

-polymer of galactose

glucans

-ploymer of glucose

glycan

-polysaccharide
-linked by glycosidic bonds

uronic acids

-tendency to form internal esters yielding lactones

glycosidases

-catalyze hydrolysis of bonds

glycosidic bond

-peptide bond of carbs

chair and boat

-chair or boat
-2 chair cnoformations depending on whether axial or equatorial

mutarotation

-formation of anomeric carbon changes rotation of polarized light

anomeric carbon

-alpha or beta anomers
-beta= balanced

epimers

-2 sugars that differ in configuration by only 1 chiral carbon

diastereomers

-2 chiral carbons that are not mirror images

enantiomers

-stereoisomers that are mirror images

glycoconjugates

-glycolipids and glycoproteins
