These additional peptides included a conjugate with selective chemical substitution in the peptide to suppress glucagon activity, a compound with a linker that proved metabolically stable and was incapable of intracellular T3 release, and a third control conjugate that carried a metabolically-inert thyroid hormone

In particular, cellular metabolic state is in constant communication with mitochondrial homeostasis

In addition to variations in the total amount of melanin [8, 9], the size, distribution, and fate of melanosomes within keratinocytes are key determinants in the diversity in skin pigmentation [11, 17, 18]
