Cholesterol has many uses for the human body including help in producing the outer coating of cells, makes up bile acids, helps with digestion of food in the intestine, and it helps make Vitamin D.

∙ 10y ago- Cholesterol can both be produced by the body itself and obtained from food sources. Cholesterol plays an important part in the human body.
- Cholesterol functions are as follows:
- Hormone production: Cholesterol plays a part in producing hormones such as estrogen, testosterone, progesterone, aldosterone and cortisone.
- Vitamin D production: Vitamin D is produced when the sun's ultraviolet rays reach the human skin surface.
- Bile production: Cholesterol produces bile acids which aid in digestion and vitamin absorption.
- Cell membrane support: Cholesterol plays a very important part in both the creation and maintenance of human cell membrane.

∙ 13y agoI added a link below. But basically it is used to maintain the structure of tissues, and it is the main component of bile which is used in digestion.

∙ 14y agoI can only think of three...
1. cell membrane integrity 2. Hormone precursur
3. energy source

∙ 11y agoNot sure about the functions but I know it's a steroid.

What are the 4 main parts of the plasma membrane?
4 major parts of a plasma membrane * proteins * lipid bilayer * carbohydrates * cholesterol
Four functions of the plasma membrane?
Four functions of the plasma membrane are:1) Serves as a gateway between the fluid inside and outside the cell. 2) Serves as a communicative device ( for molecules to bind to receptor proteins) 3) Identifies a cell coming from a particular individual. 4) Keeps the cell whole and intact.
What does cholesterol do for the plasma membrane?
Cholesterol is found in the membrane. It prevents lower temperatures from inhibiting the fluidity of the membrane and prevents higher temperatures from increasing fluidity. It stabilizes the membrane. Only animal cells have cholesterol in their membranes.
What 5 molecules form plasma membrane?
4+1
What is the difference between the plasma membrane and the cell membrane?
I've studied that the cell membrane is the same as the plasma membrane, this is true. All Cells are bounded by the/a bi-lipid layer. It is what the Cell first constructs and then produces - for export - for the building of 'The Exterior Cell Coat' that 'sets them apart'. 10-4?
What is the composition of plasma membrane?
there are four main parts of the plasma membrane of a cell. 1) the lipid bilayer: this is made up of amphipathic molecules, with the polar heads on the outsides and the non polar tails in the middle. this part is semi-permeable. 2) the proteins: these work as canals to pump larger molecules through the bilayer which couldn't otherwise fit. 3) the carbohydrates: these are different on each cell and are used as the "chemical id tag" for identifying other cells. 4) the cholesterol: this is used to keep the lipid bilayer as plasma instead of turning into a solid. hope this helps (:
What are the four major phospholipids present in the plasma membrane of mammalian cells?
The four major phospholipids present in plasma membrane of mammalian cells are: 1. Phosphatidylcholine 2. Phosphatidylethanolamine 3. Phosphatidylserine 4. Sphingomyelin. For more details click on the link below.
A lipid base molecule primarily composed of 4 interlocking rings of carbon that readily crosses a plasma membrane is?
testosterone
What three functions do lipids serve?
1. Free fatty acids are used as fuel as the produce many ATP. 2. Triglycerides are also used as fuel but are harder to break down than sugars and are stores as fat. 3. Phospholipids make up the basic structure of the cell membrane and the membrane bound organelles. 4. Cholesterol helps to build and maintain cell membranes. It stabilizes the fluid nature of the cell membrane.
What does plasma membrane do in an animal cell?
The plasma membrane, or cell membrane, had many purposes, including:-selective permeability (it controls what goes in and out of the cell)-containing the cytoplasm (and therefore allowing chemical reactions to occur)- offering limited protection to the cell, contrary to popular belief
What molecules are found in plasma membrane?
The plasma membrane's function is that it allows substances to enter or leave the cell. Its importance is that it acts as a boundary, holding the cell constituents together and keeping other substances from entering. It is found underlying the cell membrane in the cytoplasm and provides a scaffolding for membrane proteins to anchor to. -------------------------- The plasma or cell membrane is made up of a double layer of phospolipid molicules with holes through it made from proteins. For an fuller explanation as to how it is structured etc. look in the related link below phospholipids
What are Five functions of the plasma membrane?
6 Functions of Membrane Proteins: 1. Anchors 2. Identifiers 3. Enzymes 4. Receptors 5. Carriers 6. Channels A. Leak Channels B. Gate Channels I only know of four, but here it goes: - a binding site - channels for passive transport - pump for active transport - as identity markers, recognizing other cells i know all 6. --> 1. transport 2. enzymatic activity 3. signal transduction 4. cell to cell recognition 5. intercellular attachment 6. anchoring to cytoskeleton.
