Isoacyl Dipeptides
Isoacyl dipeptides are used to prepare peptide peptides in which the peptide chain is attached to a side chain oxygen atom of a serine or threonine residue instead of alpha nitrogen. Depsipeptides are less susceptible to aggregation than their standard peptide analogues because their structure di...Read more -
For effective anti-aging and anti-aging, palmitoyl tripeptide-5 is indispensable
Due to the increasing pressure of work and life, many people around the age of 20 years old, in the age of vigorous hair, the face is dark yellow, loose and drooping. If you want to achieve a bright, firm and smooth skin after the age of 20, you must have the idea of anti-wrinkle and anti-aging f...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 -
Nesiritide acetate and related precautions were briefly described
The introduction and widespread use of angiotensin-converting-enzyme (ACE) inhibitors and epinephrine P-receptor (P-receptor) blockers in the treatment of heart failure was a key turning point in pharmacotherapy for heart failure. However, the mortality rate of heart failure, especially advanced ...Read more -
Considerations for using the biotin-avidin system
1. avidin (AV) or streptavidin (SA)? Although avidin (AV) and streptavidin (SA) have high affinity for Biotin in some applications (avidin,AV) the main problem is its non-specific combination, This is due to the avidin (avidin,AV) sugar chain and higher electrical point structure (pI). Therefore,...Read more -
β-amino acids and β-high amino acids
β-amino acids and β-isoamino acids have related structures. In both, the amino group is attached to the second carbon atom of the acid group. The difference is the carbon skeleton. The β-amino acid has the same carbon skeleton as the α-amino acid, except that the amine group is attached to a diff...Read more -
Antibody-drug conjugate (ADC) peptide linker
Antibody-drug conjugate (ADC) is a targeted cancer therapy that combines the specificity of a monoclonal antibody with the cytotoxicity of a drug. Peptide adapters play a crucial role in ADC design because they link antibody and cytotoxic payloads, facilitating the control and release of drugs in...Read more -
Acetyl tetrapeptide-11 that makes loose skin moist and elastic
Syndecan-1 is a transmembrane heparan sulfate proteoglycan. The heparan sulfate side chain on the molecular surface of syndecan-1 can bind a series of ligands such as cell adhesion molecules, matrix molecules, growth factors, enzymes and enzyme inhibitors to regulate the interaction between cells...Read more -
What is the role of amino acids in food?
The requirement for essential amino acids in adults is about 20% to 37% of the protein requirement. Amino acids can act as flavoring agents in foods, some as nutritional fortifiers, and some as flavor enhancers. The taste of amino acids: Most amino acids have a taste and play a role in the taste ...Read more -
A brief introduction to gene cloning
gene cloning is the acquisition or generation of the target gene and a vector with independent replication ability to combine (vector) gene patchwork recombination, introduced into the recipient cells for asexual reproduction, and then produce new gene molecules. Since the first DNA molecular clo...Read more -
Acetyl octapeptide -3 – whether used in anti-wrinkle products
Facial wrinkles are an obvious sign and manifestation of skin aging, which is the result of the interaction of endogenous and exogenous factors. Among them, exogenous factors include collagen, elastin or mucopolysaccharide molecules, which directly damage the DNA and extracellular matrix of skin ...Read more -
The role of carnosine in antioxidation
The body’s normal metabolism is an oxidation process, and the older the age, the more oxidized the skin. Metabolites are free radicals, when the amount exceeds the maximum degree of protection of the human body, the skin will have the phenomenon of aging, which is the fundamental reason for...Read more
