The molecular weight of a peptide is derived from the ratio of its average mass to one twelfth the mass of a carbon-12 atom. It is important in peptide synthesis and can be calculated using software. Amino acids are the building blocks of peptides, and their molecular weights range from 57.05 to 156.19. Accurate molecular […]
Peptides are chains of amino acids linked by a peptide bond, classified as polymers. They perform various functions in the body, and longer chains become proteins. The distinction between peptides and proteins is based on length, with proteins being more complex. Peptides are compounds that are formed by linking one or more amino acids with […]
Cyclic peptides are a diverse class of compounds with biological activities ranging from antibiotics to toxins. They are resistant to proteases and can bind proteins in cells. They have an unusual circular structure and can be synthesized with specialized techniques. They are of interest as potential drug sources and as vectors for drug delivery. Natural […]
Different types of companies are involved in the peptide industry, including those that offer sequencing services, custom peptide synthesis, peptide libraries, and peptide suppliers. These companies rely on vendors for enzyme reagents, purified solvents, chemicals, and analytical software. GMP facilities produce peptides on an industrial scale under strict guidelines. Several distinct types of companies are […]
Antimicrobial peptides are small molecules made up of amino acids that act against microbes. They could provide alternative forms of treatment as more microorganisms become resistant to antibiotics. There are over 800 types of antimicrobial peptides, and they attack microorganisms by changing their cell membrane. Synthetic versions of histatins have shown potential in treating infections. […]
Peptide tests detect and identify peptides in a sample, providing information about their concentrations. They are used in research, diagnostics, and pharmaceutical development. Peptide dosages can help diagnose medical conditions, and labs can compare results against a peptide library. Standardized procedures reduce errors, and scientific supply companies sell equipment and solutions. A peptide test is […]
Peptide libraries are chains of amino acids used in research, drug development, and vaccine creation. They can be ordered from companies or synthesized in a lab. Libraries can be customized and come with documentation. Peptides are not strictly controlled and can be ordered easily. A peptide library is a series of peptides, chains of amino […]
Peptide nucleic acid (PNA) is a synthetic polymer similar to DNA and RNA, used in medical treatments and biological research due to its ability to store information and chemical stability. It may have been present during Earth’s earlier history and could have been used as a simpler version of DNA. PNA has found use in […]
Peptides are small polymers made up of amino acids that have various biological activities. Peptide purification is achieved through chromatography, with HPLC being the most common method. Peptide synthesis is often used to prepare rare peptides, and peptide companies can make custom peptides. Peptide purification is also used to identify proteins and to study novel […]
Peptide antigens are short chains of amino acids used to activate the immune system and develop antibodies. They can be used in vaccine development and are often part of larger proteins. Antigens are molecules that generate an immune response, and antibodies are proteins that counteract specific antigens. Peptide antigens are synthesized and injected into animals […]
Peptides are organic molecules made up of amino acids connected by peptide bonds. Synthetic peptides are made outside of cells using solid-phase peptide synthesis. They are used for research purposes, such as verifying the structure of naturally occurring peptides, studying biologically active proteins, and developing new therapeutic techniques. Peptide synthesis is also used to generate […]
Peptide antibodies are produced by the body to fight unusual forms of peptides. Citrulline antibodies attack the amino acid citrulline and are present in up to 80% of people with rheumatoid arthritis. B lymphocyte cells create different types of antibodies to attack specific antigens, and vaccines teach antibodies to destroy new pathogens. Antibodies are Y-shaped […]
Beta peptides are macromolecules made up of beta amino acids that mimic or enhance the effects of alpha peptide drugs. Unlike alpha peptides, beta peptides are not commonly found in nature. Beta peptides are used in medicine as they resist proteolysis. The Arndt-Eistert reaction is used to synthesize beta peptides. A beta peptide is a […]
Amino acid peptides are short chains of amino acids joined by peptide bonds, with less than 50 amino acids. Peptide bonds hold amino acids together and form polypeptides, which can form proteins. Peptides and proteins have various roles in animal cells and are determined by DNA. An amino acid peptide is a molecule that contains […]
Peptides are chains of amino acids that form proteins. Amino acids have amino and carboxylic acid groups, and their structure affects the properties of peptides. Peptide synthesis occurs when amino and carboxylic acid groups bond to form amide groups. Proteins have different levels of structure, including primary, secondary, and tertiary. The tertiary structure determines the […]
Peptide complexes use amino acids to create proteins that nourish the skin, and are advertised as anti-aging creams. They can restore moisture, reverse the effects of overuse, and reduce fine lines and wrinkles. They are a viable option for those who want a more youthful appearance without surgery. Peptide complexes are compounds designed to use […]
