Peptides, defined as short chains of amino acids, are fundamental biomolecules involved in numerous physiological processes.

Proteins, composed of essential and non-essential amino acids, are vital for building tissues, immune function, and muscle mass. Complete proteins, found in eggs, meat, and dairy, contain all nine ...

Peptides articles from across Nature Portfolio Atom RSS Feed Peptides are amino acid polymers. They are generally much smaller than proteins and don’t have sufficient activity on their own ...

Amino acids play a fundamental role in regulating how cells respond to drugs. These molecules, which form proteins, act like bricks that communicate with each other within a structure. In this way, ...

We prepared the eleven selected peptide–peptoid hybrids together with undecapeptides ln65 and ln69, as well as the PrAMP oncocin, to be used as positive controls, (46) using high-temperature (60 °C) ...

To emphasize the role played by the S−S bridge in the structural features of somatostatin-14 (SST-14), newly recorded CD and Raman spectra of this cyclic peptide and its open analogue obtained by Cys ...

This review summarizes the biological importance and limitations of native disulfide bonds, surveys established strategies for disulfide bond mimicry, and provide a comprehensive summary of research ...

Collagen peptides are amino acids that form collagen. Understanding how peptides affect your skin can help you make educated choices about your skincare products.
