Bacterial Peptidoglycan

2007: Q7 - Write an essay on the social organisation and function of bacteriuml peptidogly give the gate Peptidoglycan is a polymer unique to procaryotic booths consisting of polysaccharide and polypeptide chains. It is a go over component of bacterial cell walls. Structure: Peptidoglycan is a extremely crosslinked macromolecule. A disaccharide repeat parting of N-Acetyl Muramic Acid and N-Acetyl Glucosamine forms its backbone. The presence of murein indicates that this is bacterial peptidoglycan as murein is never set up in Archaea. Descending from the N-Acetyl Muaramic molecules be lypoproteins (stem peptides) consisting of D and L amino group Acids. A pentaglycine cross pair joins the D-alinine and L-lysine Amino Acids, inter-linking the Disaccharide repeat regions. Teichoic acids are embedded in the germ plasm membrane (not shown in the diagram) they thread through the peptidoglycan, attaching it to the bacterial cell. hypertext communicate protocol://www.google.ie/imgres?q=peptidoglycan+diagram&hl=en&client=fire put off-a&hs=5Jg&sa=X&rls=org.mozilla:en-US: appointed&biw=1173&bih=511&tbm=isch&prmd=imvns&tbnid=5DRtvUra9oY01M:&imgrefurl=http://pathmicro.med.sc.edu/fox/cell_envelope.htm&docid=0aWG7veP-RdY0M&imgurl=http://pathmicro.med.sc.edu/fox/sa-pep.

In Gram despotic bacteria, such as staph aureus, the peptidoglycan layer is much thicker than in Gram negative bacteria. dissimilar Gram negative bacteria, Gram positive bacteria come no outer membrane. Antibiotics such as penicillin and ampicillin can be used to deal infections involving gram positive bacteria. These antibiotics check over the formation of the peptide cross link up in...If you want to unsex a full essay, order it on our website: Orderessay
