Parathyroid hormone (PTH) is a peptide hormone that regulates calcium and phosphate balance in the body. PTH is secreted by the parathyroid glands, located near the thyroid gland in the neck. It is also known as parathormone or parathyrin. The active form of PTH, called pTH (1-34) amide, has been shown to stimulate bone resorption and to inhibit bone formation. The amino acid sequence of this hormone starts with arginine and ends with phenylalanine. The N-terminal amino acid residue is an aspartic acid or asparagine and histidine is the only basic residue in this molecule. This molecule has two acidic residues, glutamic acid and aspartic acid, which are found on the side chains of two amino acids: aspartic acid and glutamic acid. Valine is found at position 3 and phenylalanine at position 34.

N-(Fmoc-5-amino-3-oxa-pentyl)succinamic acid is a high quality chemical that is used as an intermediate in the production of pharmaceuticals and other fine chemicals. It is also a reagent for use in peptide synthesis. N-(Fmoc-5-amino-3-oxa-pentyl)succinamic acid has a CAS No. 669073-62-5 and can be used as a useful scaffold for the production of complex compounds. This compound is also useful for research purposes, due to its versatility as a building block with speciality chemical applications.

Fmoc-Tyr(Boc-Nmec)-OH is a hydrophobic amino acid that can be used in the synthesis of peptides. It is soluble in organic solvents and has been shown to have intramolecular cyclization reaction. Fmoc-Tyr(Boc-Nmec)-OH can be coupled with other amino acids using an amide bond, and has been shown to react with cationic groups such as tyrosine residues. This compound is often used in solid-phase peptide synthesis, where the product is cleaved from the resin by the action of aqueous acid or base before being purified. Fmoc-Tyr(Boc-Nmec)-OH can also be used for neutralizing alkaline conditions during peptide synthesis.

H-Arg-Phe-NH2 hydrochloride salt (H-RF) is a physiological agent that has been shown to have effects on the response element binding protein. H-RF is a small, water soluble molecule that has been shown to act as an agonist for peptides and cation channels in vitro. The peptides are involved in the regulation of cardiac function and locomotor activity, while the cation channel regulates the opening and closing of potassium channels. The binding of H-RF to these receptors leads to positive changes in energy metabolism, which may be due to its ability to activate ATPase. H-RF also binds strongly to disulfide bonds found in proteins such as peptide hormones and enzymes. These disulfide bonds are important for maintaining protein structure and function.

VIP (6-28) (human, mouse, rat) trifluoroacetate salt H-Phe-Thr-Asp-Asn-Tyr-Thr-Arg-Leu-Arg-Lys-Gln-Met-Ala-Val-Lys -Lys-Tyr-Leu is a prophylactic agent that is used to prevent the development of intestinal peptide induced myocardial fibrosis. It has been shown to reduce the incidence and severity of cardiovascular diseases. VIP (6/28) has a vasoactive effect on the intestines and may also have an effect on the cardiovascular system.
