Chapter 31, Problem 11P

Interpretation Introduction

Interpretation :

The length of the tunnel is 10 nm and the length of the translocon channel is same as the thickness of the phospholipid bilayer. The minimum number of the amino acid residues needs to be calculated.

Concept Introduction :

Amino acids are compounds containing amino as well as acidic group. The general molecular structure of an amino acid is as follows:

  ${\text{H}}_{\text{2}}\text{N}-\text{CH}\left(R\right)-\text{COOH}$

Here, R is different group for different amino acids. If there is more than one amino group present in an amino acid, they are considered as basic amino acids and if there is more than one carboxylic group then they are considered as acidic amino acids.
