Explain how peptide hormones and steroid hormones affect the metabolism of the cell

Complex media contain often protein hydrolysate which are are excellent natural sources of amino acids, peptides and proteins in growth media. It is the most important source for nitrogenous nutrients. They are most often obtained by enzymatic digestion or acid hydrolysis of natural products, such as animal tissues, milk, plants or microbial cultures. The number of available protein hydrolsate, also called peptones, is enormous and can promote and sustain the growth of most common organisms. For the enzymatic digestion often papain, pepsin, trypsin or a mixture of enzymes of the pancreatic juice are taken. Below is a list of often used expressions and the definitions.
 

Several studies have shown acute peripheral administration of PYY 3-36 inhibits feeding of rodents and primates. Other studies on Y2R- knockout mice have shown no anorectic effect on them. These findings indicate PYY 3-36 has an anorectic (losing appetite) effect, which is suggested to be mediated by Y2R. PYY-knockout female mice increase in body weight and fat mass. PYY-knockout mice, on the other hand, are resistant to obesity , but have higher fat mass and lower glucose tolerance when fed a high-fat diet, compared to control mice. Thus, PYY also plays a very important role in energy homeostasis by balancing food intake. [9] PYY oral spray was found to promote fullness. [14] Viral gene therapy of the salivary glands resulted in long-term intake reduction. [15]

It seem this may be presented backwards, somethings reversed. I would suggest that the opiates mimic the naturally occurring substances in our food which when ingested in a healthy manor in a balanced diet poses no threats to health. That opiats being the known evil here are ridding on the body's natural attraction to foods that nature intended to be good for you. This article is trying to asociate  natural atraction to some foods with an benign substance that is no good for you in any way. Guilt by association does not work for me. It may go further to help the nature of addiction to opiats than explain food addictions.

Peptide Bonds The joining of amino acids in the process of making biochemical molecules like proteins is done by bonds which are referred to as peptide bonds. This may be illustrated with the two simplest amino acids, glycine and alanine.
