Social Identity Theory and Group Selection. We can see now that, based on the social identity theory and the aspects we have talked about here, this theory and its fundamental aspects helps us to understand why people join groups.
Phospholipids are a class of lipids that are a major component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid tails and a hydrophilic head consisting of a phosphate group.The two components are joined together by a glycerol molecule.The phosphate groups can be modified with simple organic molecules such as choline.hey can form lipid bilayers because of their amphiphilic characteristic. The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid tails and a hydrophilic head consisting of a phosphate group. The two components are joined together by a glycerol molecule.
The phospholipid has a strongly polar group, the phosphate group which is hydrophilic (likes water) and a lipid or fatty acid part that is hydrophobic (dislikes water), but at â¦ tracted to other lipids and fatty acids with what is called hydrogen bonds which are common between carbon-hydrogen chains.he phospholipids make up most of the cell membrane, the cell  membrane controls what goes in and out of cells and the  phospholipids helps with this because the 'heads' are â¦ hydrophilic  and the 'tails' are hydrophobic.
