A peptide is a chain of amino acids linked to one another by amide (peptide) bonds. A peptide bond is the covalent chemical bond formed when the carboxyl group of one amino acid reacts with the amino group of another. The word peptide is derived from the greek word πεσσειν, which means "to digest." Peptides are an essential part of nature and there are thousands of them that occur naturally in the human body and in animals, but new synthetic peptides are being discovered daily, which show a prom
A peptide is nothing more than a string of amino acids that is similar to, but not identical to, a protein. To understand what a peptide is and how it differs from a protein, it is necessary to first understand what an amino acid is. **What Are Amino Acids?** Amino acids are biologically important molecules, but not all of them are used by living organisms. In fact, the human body requires only 20 different amino acids to function (the case for almost all living things), even though nearly 500 h
## What Are SARMs? SARM stands for selective androgen receptor modulator. This simply means that SARMs are androgen receptor ligands and can therefore bind to androgen receptors A and B. You might think that this means that testosterone is technically a SARMs, but this isn’t the case. Testosterone doesn’t fall into this category because, even though it binds to androgen receptors, it is not selective in its effects. It is this selectivity in action that makes SARMs so useful. Testosterone,
## What Are Peptides? Peptides and proteins are both made up of amino acids that are linked together (by peptide bonds, hence the name) in long chains called polymers. The only thing that separates peptides from proteins is how big they are. While there is no absolute cutoff, peptides are made up of fewer amino acids than proteins and hence are much smaller. In general, any amino acid chain that is longer than fifty residues in length is referred to as a protein. This is because after growing b
The last twenty years of scientific research have shown that peptides have remarkable healing properties. Peptides have been shown to improve heart function, slow the aging process, thwart neurological disease, enhance wound healing, increase bone density, reduce inflammation, help with cartilage repair, and more. From physical injury to free radical damage to the typical metabolic changes that occur with age, peptides are rapidly becoming recognized as key to improving well-being and fighting o
## Trends in Peptide Research As the ability to synthesize synthetic peptides has grown over the decades since the 1920s, something interesting has happened. Science has slowly but surely moved away from simply trying to mimic the structure of natural peptides, a practice which necessarily limited development to shorter peptides, and has instead focused on developing novel peptides that act on receptors of interest even if they bear no resemblance to native peptides. Trend in peptide len
## Voltage-Gated Sodium Channel NaV1.7 Controls Sensitivity to Pain. NaV1.7 sodium channels are nociceptors controlled by the SCN9A gene. A loss-of-function mutation in gene SCN9A reduces NaV1.7 nociceptor firing, causing CIP (Congenital Insensitivity to Pain) Disease. People born with this mutation are unable to feel most injuries, burns, et al. Conversely, there is a gain-of-function mutation in the SCN9A gene that causes NaV1.7 overactivity. It is associated with heightened pain sens
## Peptide Bioavailability (Research Context) Peptides are short chains of amino acids that are widely studied in biochemical, molecular biology, and pharmacokinetic research. A key focus within peptide science is bioavailability, which in experimental settings refers to the extent and rate at which a compound is detectable in systemic circulation or target compartments following administration in laboratory models. Historically, many peptides evaluated in research environments have been
