Bimolecular sheet
WebAll cells have a plasma membrane, a protein-lipid bilayer that forms a barrier separating cell contents from the extracellular environment. Lipids comprising the plasma membrane are amphipathic, having hydrophilic and hydrophobic moieties that associate spontaneously to form a closed bimolecular sheet. WebThe two opposing sheets are called leaflets. The favored structure for most phospholipids and glycolipids in aqueous media is a bimolecular sheet rather than a micelle. The reason is that the two fatty acid chains of a phospholipid or a glycolipid are too bulky to fit into the interior of a micelle .

Relating to, consisting of, or … Bimolecular Elementary Reactions. A bimolecular collision requires two chemicals to colloid and from collision theory the rate is proportional to the concentration of each colliding chemical with an overall order of reaction equal to two. That is, if the colliding molecules are the same species, the order of reaction is 2 for that species.
