Cholesterin – מילון אנגלי-אנגלי
Cholesterol
Cholesterol, from the
Ancient Greek chole- (
bile) and
stereos (solid) followed by the
chemical suffix -ol for an
alcohol, is an
organic molecule. It is a
sterol (or
modified steroid), a
lipid molecule and is
biosynthesized by all animal cells because it is an essential structural component of all animal (not plant or bacterial)
cell membranes that is required to maintain both membrane structural integrity and
fluidity. Cholesterol enables animal cells to not need a cell wall (like plants and bacteria) to protect membrane integrity and cell viability, thus are able to change shape and move about (unlike bacteria and plant cells which are restricted by their cell walls).
