WebDue to their amphiphilic nature, phospholipids are often used as emulsifiers. Being easily oxidized due to the presence of unsaturated fatty acids, phospholipids also exhibit … Some types of phospholipid can be split to produce products that function as second messengers in signal transduction. Examples include phosphatidylinositol (4,5)-bisphosphate (PIP2), that can be split by the enzyme phospholipase C into inositol triphosphate (IP3) and diacylglycerol (DAG), which both carry out the functions of the Gq type of G protein in response to various stimuli and intervene in various processes from long term depression in neurons to leukocyte signal pathway… how to remove empty lines in python
