In charge of the biological process. \u201cAlthough scientists have clarified the relationship between amino acids, peptides, and proteins, a key question about the origin of life has never been solved: the synthesis of peptides from amino acids requires the involvement of enzymes; The enzyme that dominates this step is a protein; but to synthesize this protein, we need amino acids to synthesize peptides first. \u201cThis is a classic \u2018chicken first or egg first\u2019 question.\u201d Professor Powner added.<\/p>\n
Previously, many scientists have been studying how amino acids spontaneously form peptides. However, the conditions required for the reaction are extremely harsh and difficult to achieve. In the study, the team focused on aminonitriles, the precursor of amino acids. They found that these molecules are inherently reactive and can directly form peptides without first converting them into amino acids. In other words, the researchers have found a way to synthesize peptides without the need for amino acids.<\/p>\n
\u03b1-amino nitrile coupling has high selectivity for \u03b1-amino nitrile coupling, so there is no need for the existence of the amino acids of these 20 proteins. Two basic characteristics make the peptide binding in water: the reactivity of \u03b1-amino nitrile and pKaH<\/sub> make them connect under neutral pH. N-acylation keeps the peptide product produced by this connection stable and activates the peptide precursor, thus achieving biologically simulated N-C peptide binding.<\/p>\n This model unifies the synthesis of amino nitrile and biological \u03b1-peptide before the origin of life, and points out that the shorter N-acyl peptide nitrile is a potentially feasible substrate in the process of early evolution.<\/p>\n References<\/p>\n Amide bond formation is one of the most important reactions in chemistry and biology, but there is no chemical way to achieve \u03b1-peptide ligation in water without using all 20 …<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[5],"tags":[28,17],"_links":{"self":[{"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/posts\/582"}],"collection":[{"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/comments?post=582"}],"version-history":[{"count":2,"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/posts\/582\/revisions"}],"predecessor-version":[{"id":588,"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/posts\/582\/revisions\/588"}],"wp:attachment":[{"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/media?parent=582"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/categories?post=582"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.creative-peptides.com\/blog\/wp-json\/wp\/v2\/tags?post=582"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n
