Nutritional quality, future research

Future research must focus on critically designed experiments to reveal the nutritional quality of organic food as compared with conventional food. 

Amino acid analysis remains an indispensable tool in a variety of biological research and development fields, e.g. the biochemical study of proteins, quality control in biotechnology and nutrition, and in clinical analyses. The classic chromatographic technologies will be for the foreseeable future the major quantitative tools for amino acid analyses. The techniques are deceptively difficult and there remains a need to standardize techniques for good quantitation. 

As an essential constituent of several important molybdoenzymes. Mo has specific roles in the metabolism of N and S in crop plants. Further studies are needed to determine the detailed structures of these molybdoenzymes and the involvement of different valence states of Mo in their reaction mechanisms. Furthermore, Mo has a wide range of nonspecific effects involving the regulation of many enzymes other than molybdoenzymes, carbohydrate metabolism, reproductive physiology, anion balance, root exudation, plant water relations, and disease incidence in plants. In the future, attempts must be made to understand the precise roles of Mo in DNA stability, protein synthesis, carbohydrate metabolism, plant stress, and disease resistance. Research is also needed on the effects of Mo nutrition on the quality of food grains and vegetable and fruit crops.
