Document Summary
Peptidoglycan - polysac cross lonked w short peptides - cell walls. Nonreduicng end: oh group at carbon 4. Attach to c4 / non reducing end. Alpha 1 to 4 for ike everything. 6 glucose units per turn of helix. Proteins that have covalently bonded carbohydrate units attached to them. Important for things outside cell like recognition clotting. Glycolysation - modified by sugar , glycans attach to proteins. Abo system based on polsacch binded, on nonreducing end. Phosphate - pentose and pyrine/prymidine on carbon 1. Adenine and guanine - purines 2 ring. Ribose more reduced form than dna oh vs h. If 2 is oh ampadpatp if its h damp adp. Na have acidic region (invariant region) - hydrophillic. Variable region hydrophobic (armoatic) not protonated/unchaged -nitrogenous bases. No on pur /pyr act as hydrogen bond accpetors. Aromatic pi orbiatls between bases above and below interact help form disulfid bonds. Major groove - distance bewteen phsophate backbone larger.
