Vitamines

Biotin is a water-soluble vitamin, also known as vitamin B7. Biotin is an essential coenzyme for five carboxylases in mammalian cells, which play key roles in the metabolism of glucose, amino acids and fatty acids (Zempleni, 2014). Biotin is also used in biochemistry in affinity purification of proteins in the biotin-avidin and biotin-streptavidin systems. Herein, free biotin is used in the elution step to release the recombinant protein from the resin (Diamandis and Christopoulos, 1991).

L-ascorbic acid, also known as vitamin C, is a natural compound with antioxidant properties. It prevents the degradation of the API in formulations, and acts as a stabilizer to adjust the redox environment and avoid side reactions with reactive species that might oxidize the drug. It is also a buffering agent, helping maintain the desired pH to improve solubility and stability.

Ascorbic acid is an essential vitamin, also known as Vitamin C, which is a naturally occurring organic compound abundant in various fruits and vegetables, including citrus fruits, berries, and peppers. Its mode of action primarily relies on its ability to donate electrons, thereby neutralizing free radicals and reducing oxidative stress at the cellular level. Furthermore, ascorbic acid acts as a cofactor for several vital enzymatic reactions, including collagen synthesis, iron absorption, and the biosynthesis of neurotransmitters.

Gamma-Tocotrienol is a form of vitamin E, which is a lipid-soluble antioxidant sourced predominantly from certain plant oils, including palm oil, rice bran oil, and annatto seeds. It possesses an unsaturated isoprenoid side chain, which differentiates it from tocopherols and contributes to its differing biological activities.

alpha-Tocotrienol is a chemical compound known as a vitamin E isoform, which is derived primarily from certain plant oils, such as palm oil, rice bran oil, and annatto. This compound exhibits a unique unsaturated side chain, distinguishing it from tocopherols and enabling it to integrate into cellular membranes with greater efficiency.

Beta-Tocotrienol is a biochemical compound that belongs to the vitamin E family. It is derived from sources such as palm oil, rice bran, and certain cereal grains. This compound exhibits its mode of action through the modulation of oxidative stress pathways and inhibition of certain enzymes involved in cell proliferation and cholesterol synthesis, which differentiates it from other tocopherols.
