Why is cholesterol important in the human body?

Answer 1

Without cholesterol, cell membranes would be too fluid, not firm enough, and too permeable to some molecules. In other words, it keeps the membrane from turning to mush.

Answer 2

Short answer:

Regarding cell activity, you need cholesterol to create cell membranes which help protect your cells. They protect it involving the process of diffusion, which means smaller particles can slide past the membrane, larger ones cannot. Without this, your skin serves no purpose and can even erode just by contact with water

Long answer:

Cholesterol is actually quite important (obviously not in high amounts) to sustain cell membrane growth which helps prevent your cells being destroyed by something as lowly acidic as water. Cholesterol helps promote hormone growth (such as testosterone and adrenaline) It also plays a role in creating vitamin D which if you didn't know helps prevent bone deformities (or osteomalacia) which helps your metabolism. Lastly, it creates bile acids that are critical to be able to digest fats and nutrients. However, you don't need and cholesterol in your diet at all since your liver produces it on it's own simply by ingesting carbohydrates and specific proteins. (In other words, have a healthy diet :)

Answer 3

They stabilize the cellular membrane and give it strength.

Answer 4

because the mitochondria expands and that would be bad in plants

Answer 5

Cholesterol in the cell membrane disturbs the close packing of the phospholipids. It helps to regulate membrane fluidity and is important for membrane stability. I hope this helped:)

Answer 6

Because they are Uniquely Designed to produce, and then provide, both structure and function(s).

Answer 7

Cholesterol provides fluidity to our cellular membranes, serves as the basis for all steroidal hormones, and functions in the production of vitamin D.

Answer 8

it maintains the membrane fluidity
