Epithalon is a tetrapeptide associated with telomeres and telomerase. It is secreted by the pineal gland and has a molecular weight of 390.3459. Telomeres are regions of DNA sequencing that halt the degradation of genes and preserve the genetic code. Telomerase replenishes the lost amount of telomeres in the aftermath of a cellular division. Epithalon's overall functionality relates to its association with telomeres and telomerase, which helps maintain the functionality of the body.
