The left diagram shows a steroid (lipid) hormone (1) entering a cell and (2) binding to a receptor protein in the nucleus, causing (3) mRNA synthesis which is the first step of protein synthesis. The right side shows protein hormones (1) binding with receptors which (2) begins a transduction pathway.
Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription , translation , post translational modifications , and protein folding .
Connective tissues proteins as collagen (zymogen: procolagen), hormones like insulin (zymogen: proinsulin) and proteins involved in development processes and apoptosis (programmed cell death) are activated by proteolysis too. Proteolysis is irreversible, which implies the need of a process of enzyme deactivation.

It raises the concentration of glucose and fatty acids in the bloodstream and is considered to be the main catabolic hormone of the body. It is also used as a medication ...
The neuroendocrine system is the mechanism by which the hypothalamus maintains homeostasis, regulating metabolism, reproduction, eating and drinking behaviour, energy utilization, osmolarity and blood pressure. The regulation of metabolism, is carried out by hypothalamic interconnections to other glands. [77]
Glycogenesis responds to hormonal control. One of the main forms of control is the varied phosphorylation of glycogen synthase and glycogen phosphorylase. This is regulated by enzymes under the control of hormonal activity, which is in turn regulated by many factors.
It is secreted heavily in pulses in between these events. Prolactin plays an essential role in metabolism, regulation of the immune system and pancreatic development. [6] [7] Discovered in non-human animals around 1930 by Oscar Riddle [8] and confirmed in humans in 1970 by Henry Friesen, [9] prolactin is a peptide hormone, encoded by the PRL ...
Progesterone regulates metabolism of carbohydrates, proteins, and lipids, resulting in physiological changes associated with pregnancy. The mix of hormones characteristic of early pregnancy promote natural growth of maternal tissues and weight gain. [ 15 ]
