What are the main functions of phospholipids and glyco- lipids in the body?
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.
Main functions of phospholipids :
In biological system, phospholipids allow cell membranes to be fluid. Their unique characteristics allow the cell membrane to take different shapes and expand and shrink when necessary.
Phospholipids can also be used as signal transducers between cells. They can be split to produce products that function as second messengers in cellular systems. As a second messenger, phospholipids can signal for leukocytes to migrate to a site of infection, and they can also inhibit neurons. Phospholipids can also be found in plants and can help produce certain plant hormones.
