Which amino acid has the smallest sidechain, and therefore would be a good one in a tight spot or corner in a protein machine?

Select one:

a. alanine

b. leucine

c. valine

d. tryptophan

e. glycine

Solution

The answer is glycine.. Glycine has the smallest side chain among all the amino acids. It\'s side chain is hydrogen \'H\'.. Due to which it can be easily rotated, twisted it bonds can be easily rotated to the appropriate size..

It\'s structure is NH3(+)-CH2-COOH(-).
