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.

Phospholipids are the essential 'bulk' part of the lipid bilayer that make up cell membranes. Phospholipids have a hydrophylic (water-loving) phosphate head and hydrophobic (w â¦ ater-hating) aliphatic hydrocarbon tails. lipid bilayer is a double layer membrane formed from phospholipids. Phospholipids are composed of a polar head group and non-polar fatty acid tails. The arrangement of the p â¦ hospholipids makes the cell membrane permeable. 4 people found this useful.
