What Are Peptides?

Peptides are short chains of amino acids that are linked together with peptide bonds. They differ from proteins, which are long chains of amino acids. The shortest peptide chains are oligopeptides, which consist of twenty or less amino acids. Other types of peptides are dipeptides, tripeptides, and tetrapeptides.

Growth hormone secretagogues

Growth hormone secretagogues are substances that boost growth hormone secretion in the body. They are a subclass of Growth Hormone Releasing Hormones and peptides. These compounds stimulate the release of human growth hormone and help the body maintain normal levels of metabolism and body structure. They also stimulate the release of Insulin-like Growth Factor (IGF) which has an anabolic effect in adults.


Skin barrier-building peptides

Peptides are an effective way to promote skin health and protect the skin from harmful elements. They improve the production of collagen, the primary protein in the skin, and strengthen the skin barrier. This helps keep the skin from being damaged by the sun, bacteria, and pollution. In addition to improving collagen production, peptides can also improve the appearance of wrinkles.


Anti-cancer peptides

Anti-cancer peptides (ACPs) are short, linear chains of amino acids that can inhibit the growth of tumour cells. They are usually about 50 AA long and are stabilized by disulfide bonds. They are designed rationally and with high specificity. They are known to inhibit specific oncogenic proteins.

Bioactive peptides

Bioactive peptides, which are small polypeptides derived from natural sources, have a variety of physiological effects. They may reduce cholesterol, lower blood pressure, and inhibit pro-inflammatory cytokines. They also have anti-inflammatory, anti-carcinogenic, and anti-microbial effects. These compounds have the potential to improve health and reduce health care costs.

A growing body of research is focusing on bioactive peptides and their physiological effects in humans. However, there are many variables that affect their levels in the blood. The peptides must be large enough to elicit the desired response, but small enough to minimize harmful effects. This is why it is so critical to develop methods for measuring bioactive peptides in the bloodstream.

Antimicrobial peptides

Antimicrobial peptides (AMPs) are molecules with antibacterial properties. They possess a unique sequence and structure that allows them to selectively bind to negatively charged bacterial cell membranes. This antimicrobial property allows AMPs to disrupt the integrity of bacterial cell membranes.

These molecules are essential for host defenses and have great potential as weapons against antibiotic-resistant bacteria. In addition to their broad spectrum of activity, peptides also have the ability to modulate complex biological responses. The field of antimicrobial peptides is rapidly evolving and multidisciplinary. Here, leading investigators discuss recent developments in the field, as well as current research methodologies and laboratory protocols for isolation and characterization.
