Q. 15.83 - An Introduction to General, Organic, and Biological Chemistry

Question

Which of the following are found in cell membranes? 

a. cholesterol

b. triacylglycerols

c. carbohydrates

Step-by-Step Solution

Answer

The correct options are (part a) Cholestrol and (part c) Carbohydrates. 

Step 1: Introduction (part a)

Lipids are found naturally components this included fats, waxes, and sterols. triglycerides, for illustration Cholesterol are fats that have included glycerol bonded to three fatty acids, such like fats and oils.      

Step 2: Given Information (part b)

 It also serves as a catalyst for the manufacture of growth factors.

Step 3: Explanation of Incorrect answer (part b)

(part b) Both fats and oils are glycosides in sequence. They are classed as "nonpolar fatty acid-containing lipids." Cattle use fats as protracted energy storage. They're molecules that aren't polar.

Step 4: Given Information (a)

Found in cell membranes.

Step 5: Explanation of Correct Answer (part a)

(part a) Cholesterol is a hydrocarbon that would be an essential constituent of the membrane of animal cells.

Thus the correct options are (a) Cholesterol

Step 6: Given Information (c)

Found in cell membranes.

Step 7: Explanation of Correct Answer (part c)

 It also serves as a catalyst for the manufacture of growth factors. Glycolipids include carbohydrates that've been linked to bilayers in living cells. 

Thus the correct options are  (c) Carbohydrates.
