Mono-unsaturated (one dbl bond): ch3ch2ch2chchch2ch3
Poly-unsaturated (2+dbl bond): Ch3ch2chchch2chchch3
Can be cis or trans (cis better)
transmembrane(both leaflets): energy, nutrients, electron transport chain
outer: flagellar activity, cell wall synthesis
1. Kill epithelial cells using toxin (RBC for hemoglobin or muscle cells for myoglobin
2. produce iron transport proteins.
NAG---NAM is beta1,4 glycosidic linkage
G+ is 100% crosslinked [4-->3], using indirect linkages ( w/ Gly)
-Direct link (not indirect)
Has initial bilayer, peptidoglycan, then another bilayer.
2nd bilayer has LPS on it.
teichoic acid interact with cell wall. attach to peptidoglycan, stick out with a degree of variability, causing different immune response, etc.
-highly conserved, toxic
2. Core Structure: 8-10 sugars. usually unique (such as KPO)
-link to outer world
3. O side chain: Repeating tetra or penta sugars
-very hydrophillic, repeat between 3-40 times.
Moderate quantities: systemic response such as fever
High quantities (such as in case of bacteremia): Septic shock [can lead to DIC]
Words From Our Students
"StudyBlue is great for studying. I love the study guides, flashcards, and quizzes. So extremely helpful for all of my classes!"
Alice, Arizona State University
"I'm a student using StudyBlue, and I can 100% say that it helps me so much. Study materials for almost every subject in school are available in StudyBlue. It is so helpful for my education!"
Tim, University of Florida
"StudyBlue provides way more features than other studying apps, and thus allows me to learn very quickly! I actually feel much more comfortable taking my exams after I study with this app. It's amazing!"
Jennifer, Rutgers University
"I love flashcards but carrying around physical flashcards is cumbersome and simply outdated. StudyBlue is exactly what I was looking for!"
