UDP-Galactose is a monosaccharide involved in nucleotide sugar metabolism. UDP-Galactose and its derivatives act as a natural agonist for Gi protein-conjugated P2Y14 receptors in the immune system (IC50=0.67 μM, hP2Y14).

Galactonic acid is a sugar acid that is a metabolic breakdown product of galactose. Galactose dehydrogenase is responsible for converting galactose to galactonolactone, which then spontaneously or enzymatically converts to galactonic acid.

Mannose 1-phosphate is an endogenous metabolite. Mannose 1-phosphate can be used to synthesize GDP-Man by the enzyme GDP-mannose pyrophosphorylase.

TRH Precursor Peptide is a precursor peptide of thyrotropin-releasing hormone (TRH). TRH Precursor Peptide formation of TRH in rat brain and pituitary is zinc-dependent.

Saccharopine (L-Saccharopine) hydrochloride, a lysine degradation intermediate, is a mitochondrial toxin. Lysine and α-ketoglutarate are converted into Saccharopine hydrochloride by the lysine-ketoglutarate reductase. Saccharopine hydrochloride is then oxidized to α-aminoapidate semialdehyde and glutamate by the saccharopine dehydrogenase. Saccharopine hydrochloride impairs development by disrupting mitochondrial homeostasis.

Acetyl-coenzyme A (Acetyl-CoA) trilithium is a membrane-impermeant central metabolic intermediate, participates in the TCA cycle and oxidative phosphorylation metabolism. Acetyl-coenzyme A trilithium regulates various cellular mechanisms by providing (sole donor) acetyl groups to target amino acid residues for post-translational acetylation reactions of proteins. Acetyl Coenzyme A trilithium is also a key precursor of lipid synthesis.
