Question

elow is some information about amino acids and a protein. The tolowing are all polar amino acids: serine, threonine, tyrosine The following are all polar, charged amino acids: aspartic acid and glutamic acid are negatively chamged histidine and asparagines are positively charged The following amino acids are nonpolar: valine, leucine, phenylalanine The following is the primary sequence of a particular protein serine, serine, glutamic acid, aspartic acid, histidine, valine, tyrosine, serine, phenylalanine, histidine a. Give an example of two different amino acids from the amino acid sequence given above that could undergo each of the following interactions in this protein: (1) hydrogen bond (2) hydrophobic interaction (3) electrostatic attraction (4) electrostatic repulsion and and and and

Explanation / Answer

1. Hydrogen bond may be formed between serine, thyrosine(proton donor) and histidine (proton acceptor.

2. Valine and phenylalanine are non polar amino acids and undergo hydrophobic interaction.

3.Histidine is positively charged and glutamic acids and aspartic acid both are - ve charged and electrostatic attractions are formed in them.

4. Glutamic acid and Aspartic acid both are - ve charged and repulsive electrostatic interaction occur betwwen them.
