Knowing the chemical properties and bulkiness (molecular weight) of amino acids

Question

Knowing the chemical properties and bulkiness (molecular weight) of amino acids indicates often the functionality of amino acids in protein structure. Sort glycine, tryptophan, phenylalanine, cysteine, and lysine by their molecular weight. Sort from lowest to highest molecular weight. View Available Hint(s) Glycine-cysteine-lysine-phenylalanine-tryptophan Cysteine-glycine-lysine- phenylalanine tryptophan Glycine-cysteine-lysine-tryptophan-phenylalanine Glycine -lysine-cysteine- phenylalanine-tryptophan

Explanation / Answer

Molecular weights of the indicated amino acids are as under-

Glycine - 75

Cysteine - 121

Lysine - 146

Phenylalanine - 165

Tryptophan - 204

Thus, the correct order would be Glycine - Cysteine - Lysine - Phenylalanine - Tryptophan.
