Â¿Alguien sabe si Orinoquia se traduce simplemente 'Orinoquia' (del espaÃ±ol al inglÃ©s) o como 'Orinoco delta'? He visto 'Orinoco delta' pero a lo mejor tiene otro matiz. Muchas gracias! IlalÃ³
1 All Biological Membranes are made of the same basic structure. 2  This is composed of molecules called Phospholipids, which form a Phospholipid Bilayer. 3  Phospholipids are fats. 4  They are composed of two Fatty Acid 'tails' and a Phosphate 'head' .
Bacterial membranes are composed of 40 percent phospholipid and 60 percent protein. The phospholipids are amphoteric molecules with a polar hydrophilic glycerol head attached via an ester bond to two nonpolar hydrophobic fatty acid tails, which naturally form a bilayer in aqueous environments.n contrast to bacterial phospholipids, which are glycerol esters of fatty acids, the lipids in membranes of Archaea are diethers of glycerol and long-chain, branched, saturated hydrocarbons called isoprenoids or which are made up of repeating C5 subunits.
