Somatostatin, also known as growth hormone-inhibiting hormone, is a naturally-occurring peptide hormone of 14 or 28 amino acid residues that regulates the endocrine system. It is secreted by the D cells of the islets to inhibit the release of insulin and glucagon, and is also generated in the hypothalamus, where it inhibits the release of growth hormone and thyroid-stimulating hormones from the anterior pituitary.Somatostatin is a tetradecapeptide which can suppress the growth hormone (GH) secretion and control the pituitary hormone secretion in human CNS.

在细胞中，当葡萄糖被己糖激酶或葡萄糖激酶磷酸化或在糖原分解过程中被磷酸葡萄糖变位酶转化为葡萄糖-1-磷酸时，会产生 D-葡萄糖 6-磷酸 (G6P)。 G6P 位于糖酵解和磷酸戊糖途径的起点。当血糖水平高时，它也可以作为糖原储存。
