NOW MOST OF US KNOW THAT CHOLESTEROL IS BAD FOR OUR HEALTH AS IT INCREASES THE RISK OF CARDIOVASCULAR DISEASES.
HOWEVER, A TINY AMOUNT IS NECESSARY FOR YOUR BODY. WITHOUT SOME CHOLESTEROL, THE PLASMA MEMBRANE OF OUR BODY CELLS WOULD BECOME TOO FLUID AT NORMAL BODY TEMPERATURE AND ARE LIKELY TO BURST OR RUPTURE.
CHOLESTEROL REDUCES THE PERMEABILITY OF THE PLASMA MEMBRANE TO MOST BIOLOGICAL MOLECULES TOO. CHOLESTEROL ACTS TO STABILIZE AND STRENGTHEN THE PLASMA MEMBRANE, GIVING IT MORE FLEXIBILITY BUT ALSO LESS PERMEABILITY TO WATER-SOLUBLE SUBSTANCES SUCH AS IONS.
