Polypeptides are compounds in which alpha-amino acids are linked together by peptide bonds and are also intermediates in protein hydrolysis. A compound obtained by dehydration condensation of two amino acid molecules is called a dipeptide, and analogously, a tripeptide, a tetrapeptide, a pentapeptide, and the like. A compound usually obtained by dehydration condensation of 10 to 100 amino acid molecules is called a polypeptide.
Description:
1. Selank is a nootropic, anxiolytic peptide based drug developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. Selank is a heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. It is a synthetic analogue of a human tetrapeptide tuftsin.
2. Selank is a synthetic analogue of the immunomodulatory peptide tuftsin; as such, it mimics many of its effects. It has been shown to modulate the expression of Interleukin-6 (IL-6) and affect the balance of T helper cell cytokines. It has been shown to influence the concentration of monoamine neurotransmitters and induce metabolism of serotonin. There is evidence that it may also modulate the expression of brain-derived neurotropic factor (BDNF) in rats.
3. Selank, as well as a related peptide drug, semax, have been found to inhibit enzymes involved in the degra
4. These effects are provided without the negative side effects typically associated , such as physical dependence, psychological addiction, and decreased motor ability. In fact, Selank is largely devoid of side effects, with the large majority of researchers claiming that it is a "side effect free" compound. This makes Selank more suitable for long-term use.

Fitness tips
How do you practice pull-ups at home? How to practice without a pole in the pull-ups?
We often say that squat is the king of action, and when considering the upper body, I want to give this crown to the pull-ups.
Pull-ups can exercise most of our upper body muscles, back muscles (latissimus dorsi muscle, rhomboid muscle), arms (two heads and three heads, forearms, grip strength), deltoids and chest muscles
In addition to so many muscle groups, the pull-ups also need very good core strength to support the movement, so it is no exaggeration to say that it is the king of upper body training!
There are many ways to perform the pull-ups, and there are many variations. Usually you only need a fixed horizontal bar!
However, for many people, there is no way to have a bar at any time and place. It is best if you can do pull-up training at home. There is nothing to pull, let yourself keep up to date!
Today, I will introduce you to a very good little trick. You don't need a bar. You only need two towels, you can pull up at home at any time!
Step 1: Choose two towels and tie the knot at one end of the towel.
Step 2: Hang the tied towel on the door
Step 3: close the door, the towel is stuck in the back of the door, avoid sliding
Step 4: Finish, start the pull-up
