Question

Describe the properties of an amphipathic alpha helix and identify numbered amino acids in a dodecamer polypeptide that contribute to the chemical properties of this secondary protein structure. Where are amphipathic alpha helices found in a globular cytosolic protein

Answer 1

Answer:

Explanation:

amphipathic alpha helix is an helix in secondary protein that one of the side has hydrophobic head and the other side has hydrophilic tail. This is formed as a result of the amino acids with either hydrophobic or hydrophilic properties is placed on the sides of three or four of the part of the backbone of the polypeptide residue.

In a dodecamer polypeptide that contribute to the chemical properties of this secondary protein structure it is found in Asp 156, Asp 157 and Glu 148.

Amphipathic alpha helices are present on the surface of the globular cytocyclic protein.
