Answer to Question #290033 in Organic Chemistry for mark

Question

what is the function of phosphtidylserine,phosphotidylethanolamine,phosphtidylinsitol.

Answer 1

The phosphatidylserine decarboxylation pathway is the main source of synthesis for phosphatidylethanolamine in the membranes of the mitochondria. Phosphatidylethanolamine produced in the mitochondrial membrane is also transported throughout the cell to other membranes for use.

Phosphatidylserine (abbreviated Ptd-L-Ser or PS) is a phospholipid and is a component of the cell membrane. It plays a key role in cell cycle signaling, specifically in relation to apoptosis. It is a key pathway for viruses to enter cells via apoptotic mimicry.

Phosphoinositides are a family of minority acidic phospholipids in cell membranes. Their principal role is instructional: they interact with proteins.Phosphoinositides also regulate the activity level of the integral membrane proteins.
