Specific triterpenoids like ganoderic acids in Reishi are also known to support liver function, enhance cardiovascular health, and promote relaxation by modulating stress responses.

Beta-Glucans

Beta-glucans are linear or branched polysaccharides composed of D-glucose monomers linked by β-(1→3) and β-(1→6) glycosidic bonds. The triple-helical molecular conformation of beta-glucans enhances their recognition by immune cell receptors, such as Dectin-1 and CR3. This structural specificity activates macrophages and natural killer (NK) cells, facilitating immune responses. Found abundantly in mushrooms such as Lion’s Mane, Shiitake and Turkey Tail, these compounds enhance the activity of immune cells like macrophages and natural killer (NK) cells. Beta-glucans stimulate the production of cytokines, aiding in pathogen defense while maintaining immune balance. They also exhibit prebiotic activity, promoting gut health by supporting beneficial gut microbiota.

Cordycepin inhibits RNA synthesis in certain pathogens and cancer cells, disrupting their replication processes. It also supports energy metabolism and endurance by improving oxygen utilization and ATP production, making it popular among athletes and for respiratory health. The hydrophobic and polar regions of cordycepin enhance its ability to interact with ATP-binding enzymes, improving its efficacy in metabolic pathways and cellular respiration.

Adenosine

Adenosine is a nucleoside composed of adenine and ribose, playing a crucial role in cellular energy transfer as a component of adenosine triphosphate (ATP) and adenosine monophosphate (AMP). It is also involved in signal transduction as part of cyclic adenosine monophosphate (cAMP), which regulates numerous physiological processes. In functional mushrooms like Cordyceps, adenosine contributes to enhanced oxygen utilization, improved cellular energy production, and increased endurance. Its ability to modulate adenosine receptors makes it a promising compound for promoting relaxation, reducing inflammation, and supporting cardiovascular health.

The molecular structure of adenosine includes a purine base linked to a ribose sugar through a β-N9-glycosidic bond. This configuration allows it to interact with enzymes and receptors, influencing energy metabolism and neural signaling pathways. In functional mushrooms, adenosine is valued for its adaptogenic properties, aiding the body’s ability to manage stress and improve physical performance.

Polysaccharide K (PSK)

Polysaccharide K, commonly known as PSK or Krestin, is a protein-bound polysaccharide extracted from Trametes versicolor (Turkey Tail mushroom). It is composed of beta-glucans with a unique molecular structure that includes a protein fraction, enhancing its bioavailability. PSK is renowned for its potent immunomodulatory properties, stimulating natural killer (NK) cells, T-cells, and macrophages to strengthen the body’s immune response.

Clinically, PSK has been widely studied for its anti-cancer effects, particularly in adjuvant therapy for gastrointestinal and breast cancers. It works by inhibiting tumor growth, preventing metastasis, and promoting apoptosis in cancer cells. Its ability to enhance the efficacy of chemotherapy and reduce treatment side effects has made it a cornerstone in integrative oncology. The molecular structure, characterized by branched beta-glucans, plays a key role in its immune-enhancing activity.

Polysaccharopeptide (PSP)

Polysaccharopeptide, or PSP, is another protein-bound polysaccharide derived from Trametes versicolor. Similar to PSK, PSP is composed of beta-glucans but differs in its specific sugar and peptide composition. PSP is known for its broad-spectrum immunomodulatory effects, including the activation of dendritic cells and stimulation of cytokine production, which are critical for adaptive immunity.

PSP has been investigated for its anti-cancer, anti-inflammatory, and antiviral properties.
