Activities of D-mannose/L-galactose enzymes in extracts from Micro-Tom immature green (IMG) and red (RD) fruitsOne unit of enzyme activity is defined as the number of micromoles of NAD⁺ reduced per minute for L-galactose dehydrogenase activity and cytochrome c reduced per minute for L-galactono-1,4-lactone dehydrogenase activity. Values are mean ±SE of three independent determinations.

	IMG	RD
L-Galactose dehydrogenase	0.34±0.09 a	0.26±0.05 a
L-Galactono-1,4-lactone dehydrogenase	1.14±0.09 a	1.89±0.15 b

Values with different letters are significantly different according to t-test (P <0.05).
