Question

according to biochemistry explain the synthesis steps of peptide hormones?

Answer 1

Peptide hormones are products of conversion. The examples are amino acids and glycoproteins. The synthesis of many peptide hormones is by prohormones, then proteolytically trimmed to make their complete form. In other circumstances, the hormones are initially entrenched within the sequence of a superior precursor, then freed by manifold proteolytic cleavages. The creation of peptide hormones takes place in the endoplasmic reticulum, then moved to the Golgi and packed into secretory vesicles for transfer. The section process might take place in one of the two following pathways.

First of all, regulated secretion is whereby the cell stocks hormone in secretory granules and reliefs them in spurts when roused. The secretion is the utmost utilized pathway. Hence, the way permits cells to conceal a large amount of hormone using less time. Secondly, constitutive secretion is whereby the cell does not pile hormone, however secreting it from secretory vesicles during the process of synthesis.

Notably, the utmost peptide hormones flow boundlessly to further proteins, even though, exceptions do exist. Therefore, the half-life of circulating peptide hormones is only a few minutes.
