There are numerous types of peptides that have been classified according to their sources and functions. According to the Handbook of Biologically Active Peptides, some groups of peptides include plant peptides, bacterial/antibiotic peptides, fungal peptides, invertebrate peptides, amphibian/skin peptides, venom peptides, cancer/anticancer peptides, vaccine peptides, immune/inflammatory ...
In chemistry, peptides are synthesized by a variety of reactions. One of the most-used in solid-phase peptide synthesis uses the aromatic oxime derivatives of amino acids as activated units. These are added in sequence onto the growing peptide chain, which is attached to a solid resin support. [130]

Creatine peptides promote the release of hormones that influence one's exercise performance, muscle recovery and body composition, which is why some athletes are drawn to the amino acids.
Like D-Peptides and β peptides, peptoids are completely resistant to proteolysis, [5] and are therefore advantageous for therapeutic applications where proteolysis is a major issue. Since secondary structure in peptoids does not involve hydrogen bonding, it is not typically denatured by solvent, temperature, or chemical denaturants such as ...
Figure 1. Classification of peptidomimetics. [1]A peptidomimetic is a small protein-like chain designed to mimic a peptide. [1] [2] They typically arise either from modification of an existing peptide, or by designing similar systems that mimic peptides, such as peptoids and β-peptides.
The threading of the lasso tail is trapped either by disulfide bonds between ring and tail cysteine residues (class I lasso peptides), by steric effects due to bulky residues on the tail (class II lasso peptides), or both (class III lasso peptides). [16] The compact structure makes lasso peptides frequently resistant to proteases or thermal ...
Nonribosomal peptides (NRP) are a class of peptide secondary metabolites, usually produced by microorganisms like bacteria and fungi. Nonribosomal peptides are also found in higher organisms, such as nudibranchs , but are thought to be made by bacteria inside these organisms. [ 1 ]
