peptides

peptides是一個英語單詞，詞性為名詞，譯為“多肽類；縮氨酸”等。多肽是由胺基酸通過醯胺鍵連線形成的化合物，分子量一般小於10kDa或少於40個胺基酸，廣泛參與生物體內系統調節。根據生理功能可分為多肽激素、免疫活性肽、抗菌多肽和抗病毒多肽等類別。多肽組指生物樣本中全部內源性多肽組份，多肽組學則系統性研究其成分、功能及變化規律。

多肽藥物因其活性顯著、毒性低等優勢成為研發熱點，口服司美格魯肽通過SNAC保護劑實現胃部吸收並於2019年獲FDA批准。深度學習技術（如RFpeptides）可精準設計環肽結構以提升靶點結合能力。全球多肽新藥臨床階段達463個，中國占75個；FDA於2023年發布多肽藥物臨床藥理學指南。《Peptides》期刊專注於多肽研究，2015年刊文探討蛻皮抑制激素對甲殼動物基因表達的調控作用。
