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.
A cell membrane is composed of a double layer of phospholipids, more commonly referred to as a phospholipid bilayer, and each phospholipid itself is important to the structure â¦ and function of the cell membrane. phospholipid is made up of a hydrophobic (water-avoiding) tail and a hydrophilic (water-liking) head. the OH group in C1 is esterified with a saturated Fatty acid. the OH group iin C2 is esterified with unsaturated fatty acid.
