Question
Chapter 2, Problem 26P
Interpretation Introduction
Interpretation:
The type of amino acid present in the alpha helix present in the proteins that span biological membranes needs to be determined. The reason for an alpha helix to exist in the environment hydrophobic to the interior of the membrane needs to be explained.
Concept introduction:
Amino acids are organic compounds containing amino as well as
Here, R group is different for different amino acids. This group can be acidic, basic or neutral.

Figure 6 shows three examples of how secondary structure elements can be arranged in relation to one another in the functional, folded form of a complete protein or one compact portion of a protein. The overall three-dimensional shape (or conformation) of a protein is its tertiary structure. • What do you think holds together the various secondary structural elements in a particular three-dimensional pattern?
