The assimilation of Ganoderma lucidum is to synthesize amino acids, nucleic acids, protein, lipids, organic acids and other organic substances. Taking various small molecular organic nutrients and inorganic compounds absorbed from the outside as raw materials, under the catalysis of various enzymes in cells, it provides material basis for the growth, development and reproduction of Ganoderma lucidum and stores energy. In addition, the assimilation of Ganoderma lucidum can also synthesize secondary metabolites, such as antibiotics, vitamins, hormones, pigments, polysaccharides, peptides and so on.
