Answer #1

Alanine and phenyalanine would react in both tertiary or quaternary structure with least chances in former than later. The protein's size, shape and reactive properties depend on the number, type and sequence of amino acids. The most important level of bonding in terms of chemical properties is represented by protein's tertiary structure. A protein's attains maximum stability and lowest energy state or reactivity in its tertiary structure. So, in tertiary structure there are least chances of reactivity.

The tertiary structure of a protein is stabilised by various ionic recations between positively and negatively charged sites on amino acid side chains, salt bridges etc.

The quarternary structure of a protein relates to inter relation and arrangement of polypeptides in a protein with more than 2 polypeptide chains.

It is possible to convert the cysteine that is a part of Cys-tRNACys to alanine by a catalytic reduction. If the resulting Ala-tRNACys were added to a mixture of ribosomes along with tRNAs correctly charged with the other 19 amino acids, all the other cofactors and proteins needed to make proteins in vitro, and mRNA for Insulin, what effect on the primary structure, tertiary structure and function of the insulin thus made would you expect?
