Figure 1.

Chemical structures of some proteic and non-proteic compounds contained in Mucuna pruriens

a) N-terminal amino acid sequences of proteins at positions (A) 1, 2, and 4 after gel separation, which are identical, and (B) at position 3, which is identical to those in A with regard to the first 10 aa, and (C) positions 5, 6 and 7, which differ from A in only in 3 aa.

b) The reaction representing the two steps involved in the formation of dopamine from l-tyrosine and the non-protein amino acid L-dopa (the main phenolic compound contained in MP)

c) Chemical structures of d-chiro-inositol and its two galacto-derivatives, O-α-d-galactopyranosil-(1→2)-d-chiro-inositol (FP1) and O-α-dgalactopyranosil-(1→6)-O-α-d-galactopyranosil-(1→2)-d-chiro-inositol (FP2), present in MP seeds.
