Somatrotropin, also commonly referred to as human growth hormone (HGH), is a hormone that is produced in the human body and excreted into the blood b the somatotrope cells of the anterior pituitary gland. It is a single-chain protein that is composed of 191 amino acids with a molecular weight of approximately 22,000 Daltos.GH secretion has many direct and indirect effects on human body. First, GH stimulates the liver's production of insulin-like growth factor (IGF-1). GH stimulates the liver's production of IGF-1.Synthetic version of Humman Growth Hormone is called Somatropin ( 191 amino acid sequence growth hormone. )Somatropin is identical to human body's own GH.
First, what are peptides? They are defined as a compound of two or more amino acids in which a carboxyl group of one is united with an amino group of another. With the elimination of a molecule of water, a peptide bond is formed. Simply put, they are basically just small proteins. Technically, anything with fewer than 50 amino acids is considered a peptide although this is not a hard and fast rule. A di-peptide is made up of two amino acids joined by one peptide bond. Tri-peptides are three amino acids bound by two peptides. So forth and so on. A polypeptide is just a long, unbranched chain of amino acids joined by peptide bonds that is not complex enough to be referred to as a protein. (Proteins are made up of polypeptides.)
Peptides, as we mentioned are made from amino acids. So, intake and production of amino acids is necessary for production of all the peptides needed for the body to work efficiently. Of course, as we age and we go through different times in our lives with different diets, stress, and physical changes some essential amino acids and peptide production is down-regulated. For example, insulin-like growth factor (IGF-1) production is reduced naturally when we are stressed and also as we age. Peptides have many functions in the body, some act like neurotransmitters, others like hormones. Many control and influence how our bodies react to diet and physical exercise. There are also several amino acids that are necessary in a sufficient amount to produce hormones like human growth hormone (HGH). If you aren’t absorbing or making enough of those amino acids, your production of that hormone will be lowered. Those of us interested in fitness and athletic goals, of course, are interested in counteracting these down-regulations so that we can maximize our bodies ability to recover, perform, and meet athletic goals.
Amino acid supplementation is pretty common among fitness buffs, but peptide supplementation is becoming more common. What’s the advantage? Well, peptides are digested and used more readily by the body as they are smaller and your body doesn’t have to break down a larger molecule. Also, peptides are more stable in the body and therefore more beneficial than unstable, unbonded amino acids.
