21
Q

polysaccharides examples

A

starch, glycogen, cellulose, chitin

22
Q

alpha formation

A

anomeric hydroxyl group below ring

23
Q

beta formation

A

anomeric hydroxyl group above ring

24
Q

storage polysaccharides are made from

A

alpha-monomers

25
structural polysaccharides are made from
beta monomers
26
storage polysaccharides include
complex carbs, starch (planets), glycogen (animals)
27
.
.
28
storage polysaccharides features
digestible, helical phone cord structure and store energy
29
glycogen
storage polysaccharide | 1-6 linkages to form branches
30
branches are good for
releasing energy more at once, not for storage
31
structural polysaccharides
dietary fiber, cellulose (plants), chitin (insects, crustaceans)
32
cellulose made from
beta glucose, 1-4 linkages
33
structural polysaccharides structure
straight linear structure that hydrogen bonds with other strands to form woody fiber
34
animals do not have enzymes to break down/ digest
beta 1-4 linkages
35
oligosaccharides
sugars of 3-40 monomers, many different simple sugars, | highly branched
36
oligosaccharides function
cell recognition/signaling and cell defense
37
blood types result from
oligosaccharides
38
amylose
plants | storage alpha 1-4 helical
39
amylopectin
plants storage alpha 1-4 helical alpha 1-4 branches
40
glycogen
storage animals alpha 1-4 helical alpha 1-4 branches
41
cellulose
structural plants | beta 1-4 lines (wood)
42
chitin
structural animals | beta 1-4 lines (exoskeleton)
43
storage
plants: amylose, amylopectin animal: glycogen
44
structural
plants: cellulose animals: chitin
45
how to tell beta from a structure
top, two oxygens are close together and they are up
46
how to tell alpha from a structure
bottom, oxygens are across and one is facing down
47
monosaccharides 4 main points
1. glucose, galactose, fructose, ribose, deoxyribose 2. general naming (kato vs aldo; di, tri,tetra, penta, hexa) 3. find anomeric carbon 4. # a chain
48
main 2 points of disaccharides
1. glycosidic bond used two diff. hydroxyl | 2. maltose, sucrose, lactose
49
main 2 points of oligosaccharides
1. highly branched | 2. cell recognition and cell defense
50
main 2&3 points for polysaccharides
storage: plants --> 1) amylose alpha 1-4 helical. 2) amylopectin: alpha 1-4 helical and alpha 1-6 branched. 3) animal --> glycogen: a1-4 helical and a1-6 branched structural: plants --> 1) cellulose: b1-4 lines (wood). animals --> 2) chitin b1-4 lines (exoskeleton)
