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' .
All living things contain organic macromolecules: Lipids, proteins, carbohydrates and nucleic acids. Characteristic for these organic molecules is that they are made up of only a small number of elements: carbon, hydrogen, oxygen, and to smaller amounts nitrogen, phosphorus and sulfur. Lipids are also an important component of the cell membrane. 2  Lipids consist of glycerol and fatty acids tails. 3  The fatty acid tails are long chains of carbon and hydrogen that contribute to the non-polar behavior of fats-they don't mix with (polar) water.
