Enzymatic peptides that lead to healthy living
It used to be thought that the body absorbed proteins mostly as amino acids. In recent years, international scientific research has shown that protein is usually absorbed by the body in the form of small peptides after enzymatic hydrolysis of the digestive system, which is easier and faster to be...Read more -
Oligopeptide 10 A peptide that repels acne bacteria
The predominant manifestation of skin lesions in acne is comedones. The reason is that the hair follicle sebaceous glands secrete more oil, after secretion, the discharge is not very smooth, and sometimes the opening will shrink in a piece, it will form acne. Acne is a common type of skin disorde...Read more -
How to increase the solubility of peptides?
Peptides are widely used in the pharmaceutical industry, raw materials, dyes and other fields. The solubility of peptides is a key factor affecting the success or failure of laboratory experiments. Generally, the solubility of peptides is closely related to the amino acid sequence of the whole pe...Read more -
What are the effects of melittin and how to obtain it?
Melittin is the core component and main bioactive substance of bee venom, accounting for about 40%-50% of the dry weight of bee venom. Melittin is strongly alkaline and soluble in water. It is one of the most powerful anti-inflammatory substances known to people at present, and has the following ...Read more -
Synthetic peptides are an important breakthrough in the treatment of stroke
Surveys show that one out of every six people in the world will have a stroke, one person will die from a stroke every six seconds or so, and one person will be disabled for life because of a stroke every six seconds. Stroke is a group of diseases with cerebral ischemia and hemorrhagic damage as ...Read more -
Processing of walnut protein peptides and advantages of the applied membrane separation technique
Walnut protein is a good plant protein resource, but there are few studies on it in our country, especially on its protein hydrolysate walnut polypeptide. Walnut polypeptide is a kind of plant protein with multiple physiological functions. Among them, walnut contains very high essential fatty aci...Read more -
Oligopeptide-68, a polypeptide that can effectively inhibit melanin formation
Our skin color is influenced by the red protein in our blood vessels, the yellow carotenoids in our subcutaneous tissue, and the light pigment mechanism of melanin. Melanocytes are able to form melanin. The color of the skin is mainly affected by the content and distribution of this pigment. The ...Read more -
What conditions can be related to the breakdown of polypeptide synthesis
Drugs can be hydrolyzed by acids, bases, proteases or metal ions under certain conditions. “For example, the half-life of the hydrolysis of dipeptide glycylglycine in 1mol/LNaOH is approximately 2 days at 25 ° C, and 150 days in 1mol/L hydrochloric acid.” However, the difficult-activa...Read more -
Some questions and answers about the solubility of modified peptides
1. What impurities are there in the non-HPLC purified ones? A: Modified peptide and non-modified peptide impurities in crude and desalted modified peptide: such as non-full-length modified peptide and some raw materials such as DTT, TFA, etc. 2. What impurities are purified by HPLC? A: The modifi...Read more -
What is protein purification and classification?
Protein purification is the process of separating protein fractions of a specific purpose from tissues, cells, or protein mixtures. Protein purification should not only promote a strong purity of the isolated protein, but also maintain the biological activity of the protein. Therefore, it is nece...Read more -
What is a glucopolymer? What are its advantages?
1. What is a glucopolypeptide? A high polymer in which numerous glucans are rearranged and cross-linked together is a glucopolymer. All carbohydrates that people usually eat will eventually be converted into glucose to be absorbed by the body and become nutrients. Glucan is a polymer that combine...Read more -
Green and sustainable peptide synthesis industry
Peptide chemical synthesis of choice is basically solid phase peptide synthesis (SPPS), can accept ordinary synthesis of the vast majority of any kind of peptide sequence, mainly containing complex or cyclic peptide products. However, synthetic strategies considering solid-phase peptide synthesis...Read more
