From: Iron deficiency affects nitrogen metabolism in cucumber (Cucumis sativusL.) plants

Aa	+Fe (0d)/-Fe (7d)		N/C
	root	leaf
Asp	−49	+125	C₄H₇NO₄	0.25
Asn	0	+1.263	C₄H₈N₂O₃	0.50
Gln	−64	+350	C₅H₁₀N₂O₃	0.40
Glu	−53	+138	C₅H₉NO₄	0.20
Gly	−25	+160	C₂H₅NO₂	0.50
Ser	−12	+94	C₃H₇NO₃	0.33
Arg	−96	−35	C₆H₁₄N₄O₂	0.67

Values are the ratio determined between 0 and 7 days of treatment. N/C is the ratio between Nitrogen and Carbon concentration in the molecule.
