25
gram positive
piurple dye syicks to petidogycan mixture protein and carbhydrate inside
26
gram emegative
peptidoglycan outisde so dye cant travel thrugh memebrane
27
carbohydrates sugnalling
glyoprotein
28
glycan
o an dnN o = censensus
| N recognised due to certain sequence
29
glycan in blood
```
a = glycan and connected to ligan or protein
b= galctose
o= lack sugar
```
30
glycoaminoglycans
long unbranched repeating carboxyl and sulphate v neg brings in water elastic viscous for sopnal fluiod eye

heteropolysaccaride
heparin binds to anttithrombin
| hylaronic acid hihg neg charge - found in sin draws lots water

proteoglycan
bottlebrush model= largw mix carbohydrate proteins
34
lectin binf to carbohydrate
recognition faste release danger signals
