Glutamine Peptide GP-1

Product overview

In our research into wheat, Nisshin Seifun Group has focused on gluten, a protein that is believed to play an important role in the texture of bread and udon noodles. Wheat gluten has a higher glutamine content than gluten found in other foods, but it is insoluble in water. Glutamine Peptide GP-1 is a powder with gluten that is partially broken down by enzymes to make it water-soluble so that it can be used in the development of products for a range of different purposes.

Overview of ingredients

Glutamine Peptide GP-1 contains various peptides that are rich in glutamine. Glutamine is a versatile amino acid that is most abundant in muscle tissue, and it plays important roles in the body that include acting as an intermediate metabolite of bioactive compounds, transporting nutrients between tissues, and maintaining body pH. Glutamine is used in the intestine and immune cells (lymphocytes, neutrophils, macrophages) at a rate equal to or greater than that of sugar. Glutamine is similar in name to glutamic acid, which is well known as a flavor component, but it has different structure and functions.

Characteristics of product

Solubility in water

Though glutamine will only form a 3% solution in water, Glutamine Peptide GP-1 has been confirmed to dissolve to a 30% solution in water (approximately 9% glutamine).

Stability in aqueous solution

In a free state, glutamine is unstable because it is easily broken down by heat, water, or gastric acids, and it is easily converted into another component called pyroglutamic acid. Glutamine Peptide GP-1, however, is relatively stable because it consists of peptides of interconnected amino acids.

Efficient supply of glutamine to the body

As a peptide, Glutamine Peptide GP-1 has the advantage of having a number of routes of absorption. Free glutamine is primarily metabolized in the intestines, and it may not contribute to increasing glutamine in the body. However, glutamine dipeptides (e.g., Ala-Gln, Gly-Gln, Arg-Gln) are also absorbed by oligopeptide transporter 1 (Pept-1), thus efficiently delivering glutamine to the blood and tissues.

Application in a wide range of product forms

Glutamine Peptide GP-1 is highly resistant to water and heat and has good processability, making it suitable for use in the development of products in various forms, such as instant beverages, granules, and jellies.
