Document Summary
Do(cid:374)"t (cid:374)eed to memorize sequence of amino acids. Have a disaccharide with a peptide, one difference in peptide in gram positive you have lys, in gram negative you have dap. Think of this unit as being a brick to build a wall. Schematic of cell wall, have a polymer of peptidoglycan units. Have peptide, that allows you to make a polymer / one layer. Within gram positive there are multiple layers, to make a solid / rigid each layer is linked to the next layer, and lipids occur through peptide chains. Gly is an amino acid, found in every organism, dap is unique to gram negative (cid:271)a(cid:272)teria, do(cid:374)"t fi(cid:374)d it i(cid:374) any other organism. Cell wall is build and bacteria wants to get bigger, in order to grow you need to break the box to make it bigger, this is synthesis, which only occurs when the cell wall is growing. This is only done if bacteria is growing or reproducing.
