Peptide, any organic substance of which the molecules are structurally like those of proteins, but smaller. The class of peptides includes many hormones, antibiotics, and other compounds that participate in the metabolic functions of living organisms.
人體的活性物質都是以肽的形式存在,肽是機體完成各種複雜的生理活性必不可少的參與者。肽涉及到人體的各個領域, 肽是生命存在的形式,沒有肽,生命就沒有可能活下去。
Amino acids are a major part of our biology. Known as ”The Building Blocks of Life” – its fairly simple to understand our greatest functional potential in the body is created through protein. Surprisingly 20% of the human body is actually made up of protein and protein has a very important role.
肽是介於氨基酸和蛋白質之間的物質,是由兩個或兩個以上的氨基酸以肽鍵相連的結合物。不同種類不同數量的氨基酸,通過排列組合則可以構築成百上千種肽。
Proteins and peptides are fundamental components of cells that carry out important biological functions. Certain types of peptides play key roles in regulating the activities of other molecules. Structurally, proteins and peptides are very similar, being made up of chains of amino acids that are held together by peptide bonds.
食物中提供的異體蛋白質進入人體後不能直接被人體利用,必須分解成人體需要的20種氨基酸(amino acid),才可能重新組建成人體自身的蛋白質。
