Match the structural lipid with its general function. Choose the best answer. acts as a second messenger in signaling transduction is the most abundant membrane lipid has a role in blood clotting cascade defines microdomains within the plasma membrane is the most abundant lipid within brain tissue aids in budding and fusion of vesicles A. PI: phosphatidylinositol B. PC: phosphatidylcholine C. PS: phosphatidylserine D. Chol: cholesterol E. SM: sphingomyelin F. PE: phosphatidylethanolamine

Expert Solution

A. PI: phosphatidylinositol - acts as a second messenger in signaling transduction

Phosphatidylinositol (PI) acts as a lipid second messengerin the regulation of signal transduction, actin cytoskeleton dynamics, adhesion, vesicle trafficking, and motility.

B. PC: phosphatidylcholine - is the most abundant lipid within brain tissue

PC(16:0/18:1) is the most abundant species of phosphatidylcholine is in the brain.

C. PS: phosphatidylserine - has a role in blood clotting cascade

The main biological function of phosphatidyl serine in cells is blood coagulation and apoptosis,

D. Chol: cholesterol - is the most abundant membrane lipid

Phospho-lipids, glycolipids, and cholesterol are the three major kinds of membrane lipids.

E. SM: sphingomyelin - defines microdomains within the plasma membrane

Sphingomyelin is associated with lipid microdomains in the plasma membrane known as lipid rafts.

F. PE: phosphatidylethanolamine - aids in budding and fusion of vesicles

Phosphatidylethanolamine has a central role in the budding and fusion of vesicles.

1. Choose the best match. Each of the answer can only be used once! This type of bonds occurs both between fully charged group and between the partially charged groups on polar molecule. Hydrogen bonds This type of bonds forms when two atoms come very close together to share one or more of their electrons. Covalent bonds This type of bonds form when a hydrogen atom is â sandwichedâ between two electron-attracting atoms (usually oxygen or nitrogen). Hydrophobic forces This...

Discuss the general structure and function of lipid rafts Compare the 3 types of membrane proteins in terms of their affinity for the hydrophobic interior of the membrane and the functions they typically have in cells. Think about how some of these functions are dependent on the presence of other types of membrane proteins (e.g. given that some peripheral membrane proteins anchor integral membrane proteins, how would removing peripheral proteins affect the mobility of integral membrane proteins?) Discuss the meaning...
