Cholesterol
The animal plasma membrane is a layer of phospholipids that is entwined with cholesterol and proteins. Cholesterol makes up a small part of the cell membrane's mass and it is present in every cell of the body. Cholesterol maintains the integrity of the cell membrane. It assists in the immobilization of the outer surface of the cell membrane and it reduces the permeability of the membrane to most biological molecules. Cholesterol also perform roles in cell signaling, maintaining fluidity  and protecting important proteins in the membrane.

Explanation:
%DV label= 27% 
1 cup of cooked collared greens= aprx 266.60 mg of Calcium
Assuming Clara is... 
- a teen, her required adequate intake (RAI)=  1300 mg/ day
- an adult, her RAI= 1000 mg/day
For teenaged Clara
∵27 % DV= 270mg
% daily Calcium=   = 20.8 ≈ 21%
 = 20.8 ≈ 21%
=0.21 
<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>
Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.
