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 up 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, 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 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.
