Slightly more nerdy answer: because peptides are small, they can bind directly to cell receptors and trigger specific biological effects
nanomolar in cell culture Important: These are experimental doses used in animal studies and cannot be extrapolated to other species due to significant differences in metabolism, receptor density, pharmacokinetics, peptide degradation rates, and PepT1 expression patterns
Excretion Pathways Limited data on combined excretion indicates: Primarily renal elimination of peptide fragments Hepatic metabolism contributes to overall clearance Copper recycling through normal physiological pathways No evidence of accumulation in chronic dosing studies (animal models) The relationship between rapid plasma clearance and prolonged biological effects represents a key area requiring further mechanistic investigation across all three components

In addition to treating vitamin B12 deficiency, hydroxycobalamin injections have also been used to treat certain types of neuropathy, cyanide poisoning, and other medical conditions
