H2S Donor 5a is a H2S donor that could mimic the slow and continuous H(2)S generation process.

Pyridoxal represents an active form of vitamin B6 [1].

Erythronic acid, an endogenous carbohydrate metabolite, is instrumental for research into metabolism-associated disorders. It significantly influences both the development and amelioration of hyperuricemia and is associated with mitochondrial dysfunction in cases of transaldolase deficiency [1].

D-Tagatose (D-(-)-Tagatose), a rare natural hexoketose, is an isomer of d-galactose. D-Tagatose occurs naturally in Sterculia setigera gum, and it is also found in small quantities in various foods such as sterilized and powdered cow's milk, hot cocoa, and a variety of cheeses, yogurts, and other dairy products. It can be synthesized from D-galactose by isomerization under alkaline conditions in the presence of calcium. D-Tagatose have numerous health benefits, including promotion of weight loss, no glycemic effect, anti-plaque, non-cariogenic, anti-halitosis, prebiotic, and anti-biofilm properties, organ transplants, enhancement of flavor, improvement of pregnancy and fetal development, treatment of obesity, and reduction in symptoms associated with type 2 diabetes, hyperglycemia, anemia, and hemophilia.

L-Tartaric acid ((2R,3R)-(+)-Tartaric acid) occurs naturally in many plants, particularly grapes and tamarinds, and is one of the main acids found in wine. It is used as an antioxidant. Salts of tartaric acid are known as tartrates. L-Tartaric acid is a muscle toxin, which works by inhibiting the production of malic acid, and in high doses causes paralysis and death.
