1.6 Amino acids
Amino acids are the building blocks for the synthesis of proteins which
includes antioxidant enzymes. Some of the amino acids can directly
scavenge oxygen free radicals. Out of 20 essential amino acids present
in mulberry leaves, four amino acids, Asparagine, Alanine, Proline and
GABA were observed and their structures are shown in figure 4. Mulberry
leaves contains high amino acid contents which are nutritively superior
and also promote growth and development of silkworm [21,22].
