Unlike most abundantly synthesized molecules, such as ATP or DNA, the production of GSH is controlled at the enzymatic level by a holoenzyme, glutamate-cysteine ligase (GCL), a heterodimer composed of a catalytic subunit (GCLC), and a modifier subunit (GCLM)
Unlike many nutrients, B12 is produced exclusively by bacteria and obtained primarily through animal-based foods including meat, fish, eggs, and dairy products
Therapy with bovine pancreatic enzyme extracts is not sufficient to restore cobalamin absorption in dogs with EPI, as intrinsic factor appears to be species-specific

We are currently exploring cationic or neutral water solubilizing groups to replace the carboxylic acids in RT to achieve higher temporal resolution while maintaining homogeneous cellular distribution, which will be reported in the due course
Some advanced protocols combine multiple hair-specific peptides, using each for its unique mechanism
