DSIP CAS62568-57-4 human growth Peptides muscle building supplements​

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.

Product Details

Description:

Delta sleep-inducing peptide, abbreviated DSIP, is a neuropeptide that when infused into the mesodiencephalic ventricle of recipient rabbits induces spindle and delta EEG activity and reduced motor activities.

Delta sleep-inducing peptide was first discovered in 1974 by the Swiss Schoenenberger-Monnier group who isolated it from the cerebral venous blood of rabbits in an induced state of sleep. It was primarily believed to be involved in sleep regulation due to its apparent ability to induce slow-wave sleep in rabbits, but studies on the subject have been contradictory.

DSIP is an amphiphilic peptide of molecular weight 850 daltons with the amino acid motif: N-Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu-C
It has been found in both free and bound forms in the hypothalamus, limbic system and pituitary as well as various peripheral organs, tissues and body fluids. In the pituitary it co-localises with many peptide and non-peptide mediators such as corticotropin-like intermediate peptide (CLIP), adrenocorticotrophic hormone (ACTH), melanocyte-stimulating hormone (MSH), thyroid-stimulating hormone (TSH) and melanin concentrating hormone (MCH). It is abundant in the gut secretory cells and in the pancreas where it co-localises with glucagon.

In the brain its action may be mediated by NMDA receptors. In another study Delta sleep-inducing peptide stimulated Acetyltransferase activity through α1 receptors in rats.It is unknown where DSIP is synthesized.

Fitness Tips~~

Supine leg lift: supine leg lift exercise abdominal rectus lower part graphic tutorial
Lying Leg Raise, for people with weak upper limbs, it is easier to control the lifting leg on the plate. A little more difficulty can be placed on the sloping board for the upper reclining leg, called the Incline Leg Raise.

Target exercise muscle: lower rectus abdominis (lower abdomen)

Action essentials:

1. Lying on a mat or a flat bench (but both hands should be able to hold the stool to keep it stable). During the movement, the upper back, arms and hands are kept fixed.

2. Close and straighten your legs, lift your legs until the thighs are perpendicular to the ground; pause, recover, repeat

Precautions:

1. Close and straighten your legs during the movement. Lift your legs up to the vertical position. Do not leave the lower back, otherwise the back will start to participate.

2. When restoring your legs, do not touch them to the ground to keep your abdominal muscles strained.

3. Do not use inertia to complete the action, slow down the speed and rely on the strength of the abdominal muscles to control

4. Increase the difficulty to clamp the dumbbells on both legs; or after lifting the vertical position of the legs, further move the legs up vertically.

5. It is also possible to alternate legs, 4 time abs, refer to "Abdominal Exercise Video: Eight Basic Actions"
