Amino Acids and Polypeptides
Amino acids are compounds that combine to form proteins. They are also needed for vital processes such as the synthesis of hormones and neurotransmitters, as well as the building of protein.
If you would like to buy amino acids for your research projects, we have a wide range of products for you. Scroll down to view our full range of amino acid research hormones and polypeptides for sale.
What are Amino Acids?
According to scientific research, amino acids are organic compounds composed of oxygen, hydrogen, nitrogen, and carbon.
When proteins are broken down, amino acids are left. They are used to make proteins, which help grow[i], repair, break down food, and create energy. Ultimately, amino acids function as a source of energy and are classed into three groups:
Essential amino acids
Nonessential amino acids
Conditional amino acids
Essential Amino Acids
Your body requires 20 different amino acids to function optimally. However, only nine amino acids are considered essential: histidine, isoleucine, leucine, tryptophan, valine, lysine, methionine, phenylalanine, and threonine.
Nonessential Amino Acids
Nonessential amino acids include: alanine, arginine, asparagine, aspartic acid, glycine, proline, serine, tyrosine, cysteine, glutamic acid, and glutamine.
Conditionally Essential Amino Acids
Conditional amino acids are mainly essential in times of illness and stress. These acids include: arginine, cysteine, glutamine, ornithine, proline, serine, tyrosine, and glycine.
What is a Polypeptide?
Polypeptides are chains of amino acids[ii] linked together by protein bonds. Short polypeptides are named based on the number of monomeric amino acids that make them. For example, a dipeptide is comprised of two amino acids sub-units and a tetrapeptide is made of four amino acid sub-units.
At the end of every polypeptide, known as the amino terminal, there is a free amino group. At the other end, there is a free carboxyl group known as the carboxyl terminal.
A polypeptide amino acid sequence is determined by the codons in the mRNA molecules from which it was converted.

Bioregulators: A New Frontier in Peptide Research
The realm of peptide research has witnessed significant advancements over the years, with Bioregulators emerging as a promising category. These specialized peptides hold the potential to revolutionize various fields, from medicine to cosmetics.
What are Bioregulators?
Bioregulators, often termed as “bioactive peptides,” are short chains of amino acid residues that can influence biological processes. Unlike traditional peptides, Bioregulators are specifically designed to interact with cellular mechanisms, guiding them toward a particular outcome, such as regeneration or repair.
How Do Bioregulators Work?
At the molecular level, Bioregulators function by interacting with specific receptors on the cell surface. Once bound, they can modulate cellular activity, either amplifying or inhibiting specific pathways. This targeted approach allows for precise interventions, making Bioregulators a valuable tool in research and therapeutic applications.
Benefits of Bioregulators
Targeted Action: Bioregulators are designed to act on specific cellular pathways, ensuring a focused and efficient outcome.
Versatility: They can be tailored for various applications, from skin rejuvenation to cartilage repair.
Safety: Due to their precise mechanism of action, Bioregulators often exhibit fewer side effects compared to broader-acting compounds.
Advantages Over Traditional Peptides
Precision: Bioregulators offer a higher degree of specificity in their interactions.
Flexibility: Researchers can design Bioregulators for a wide range of applications.
Efficiency: Their targeted nature often results in quicker and more pronounced results.

Melanocyte-stimulating Hormone
If you are looking to buy melanocyte-stimulating hormones for your research projects, we have a full range of products for you to choose from as of August 2023. Scroll down to see our full range of alpha-melanotropin research hormones.
What is Melanocyte-stimulating Hormone?
Melanocyte-stimulating hormone is produced by the skin, hypothalamus, and the pituitary gland. It is the collective name for MSH peptides and plays a key role in producing colored pigmentation in the skin. By inducing specialized skin cells known as melanocytes, it creates a pigment called melanin, which protects cells from DNA damage.
Melanotropin hormones or intermedins are a group of hormones separated into three categories:
Alpha-Melanocyte Stimulating Hormone (a-MSH)
β-melanocyte-stimulating hormone (β-MSH)
γ-melanocyte-stimulating hormone (γ-MSH)
How it Works
Following the release from the pituitary, Alpha-melanocyte-stimulating hormone[i] circulates in the blood and attaches to MCRs on pigment-containing cells known as melanocytes. In humans, the process leads to skin darkening with sunlight exposure functioning as the incentive for MSH production and secretion as research has shown.
MSH Effects
While Melanocyte-stimulating hormone, also known as Alpha-MSH, is mainly known for its effect on pigment cells[ii], it can also supress appetite by manipulating receptors in the brain. That’s why it’s known both as a tanning treatment and as a weight loss treatment.
It also possesses powerful anti-inflammatory effects which can influence aldosterone hormone release, and has an effect on sexual behavior.
Buy Melanocyte-stimulating Hormone
Would you like to purchase melanocyte peptide for your scientific research? It is important to choose a professional, reliable, and respected company from whom to order these hormone chemicals.
