Abstract:
nutrients are closely related to consumer health. In this study, the contents of 22 amino acids in four glutinous rice varieties were quantified by LC-MS-targeted metabolomics, and the relationships between nutritional components and metabolites were analysed. The results demonstrated that gingerglycolipid B and pantothenic acid were significantly negatively correlated with Ala. The Lys and Cys-Cys contents of ZN18 and YZN were significantly higher than those of YCN and ZN20. Citric acid was significantly positively correlated with Lys and Cys-Cys. The ascorbic acid content of YZN and ZN18 was significantly higher than that of YCN and ZN20. YZN had the highest Mn, Zn, Ca, and crude fat contents. Gingerglycolipid B and pantothenic acid were significantly negatively correlated with Mn and Zn. Gingerglycolipid B and pantothenic acid are closely related to other nutritional components, and they are important metabolites formed by the nutrient components of purple glutinous rice.

Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...
