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' .

Cooking oil, for example, is made up of lipids. Lipids are used in the cell membrane precisely because they won't mix with water, meaning they form an effective barrier between the water solution inside the cell and the environment outside.
