Use | L-zinc aspartate is an amino acid chelate. Zinc aspartate is an important zinc supplement. Zinc is one of several trace elements necessary for the human body, and its content in the human body is second only to iron. The effects of zinc on human physical growth, mental development and health have been paid more and more attention. Zinc is related to the activity of nearly 300 enzymes in human body. It is widely involved in the metabolism of nucleic acids and proteins, so it also affects the growth, division and differentiation of various cells, especially DNA replication. Zinc can speed up cell division and keep cell metabolism at a high level; it can enhance the phagocytic ability of macrophages; it can promote the development and division of brain cells, and lay a solid material foundation for children's intellectual development. is a new generation of trace element additives, which can be used as food additives and pharmaceutical intermediates |
preparation method | 20g calcium carbonate (calcium content: 38%) is dispersed in 500ml of water, stirred and dissolved, 60g aspartic acid is added to the solution for reaction, and then the solution is continuously stirred until the calcium carbonate and aspartic acid are completely dissolved. Then 30g of zinc sulfate (zinc content: 35%) was added to the reaction mixture to form a white calcium sulfate precipitate. After the reaction was incubated for 30 minutes, the resulting solution was centrifuged to remove the insoluble matter and the clarified supernatant was separated. The supernatant was freeze-dried to obtain about 67 g of soluble zinc L-aspartate. |
