BCHS 3304 -EXAM 4 Questions and CORRECT
Answers
carbohydrates are main up of
CH2O chains
monosaccharide
single sugar molecule
oligosaccharide
A polymer containing a small number of monosaccharides.
polysaccharide
large macromolecule formed from monosaccharides
glycosidic bonds
a covalent bond that attaches one monosaccharide to another
what kind of glyosidic bond does cellulose have?
B(1-4) linakge
what kind of glyosidic bond does amylose have?
a(1-4) linkage
chitin
A structural polysaccharide, consisting of amino sugar monomers, found in many fungal cell
walls and in the exoskeletons of all arthropods.
, biofilm
a microbial community that usually forms as a slimy layer on a surface; can create barriers to
antibiotics and can cause big problems in medical devices to oil or water pipes
proteogylcan
protein + GAG, consisting of
oligosaccharides can
- help define protein structure (flexible, etc)
- influence the way proteins fold
- mediate recognition events
lectins
surface proteins that bind to specific carbohydrates
ricin
found in seeds of castor seed plant;
potent poison; 1.8 mh can kill can adult
ribosome inactivating protein, cleaves adenine N-glycosidic bond on 60S
needs B subunit to be deadly
selectin
attaches white blood cells (leukocytes) to endothelial cells
if endothelial cells acquire damage,
the white blood cells help eliminate that damage
