Q. 15.63 - An Introduction to General, Organic, and Biological Chemistry

Question

Where are proteins located in cell membranes?

Step-by-Step Solution

Answer

Peripheral molecules are still only detected on a few of the membrane's surfaces. 

Step 1: Introduction

• Compulsive overeater lipids and proteins constitute the majority of cytoplasmic membrane.
• Lipid bilayers and polyphenols are the two main forms of membrane phospholipids (generally cholesterol). 
• The distinguishing feature of lipids is their tendency to absorb freely in alcohols.

Step 2: Given Information

Additionally, they both seem to have a moisture and dissolving portion.

Step 3: Explanation

Integral proteins reach through to the phospholipids towards both surfaces, whereas peripheral molecules are still only detected on a few of the membrane's surfaces.
