指稱存在於皮膚、肌肉、肌腱、韌帶和骨頭中的一種纖維狀細胞外基質蛋白。膠原蛋白的構成是先以甘胺酸¬¬-脯胺酸-羥基脯胺酸作為重覆單元形成線狀的多胜肽鏈，接著每三股分子鏈相互纏繞並與氫鍵交聯，最後形成剛性的螺旋結構。含有膠原蛋白的材質，諸如毛皮，骨頭和魚等，自古以來便用於製作動物膠。膠原蛋白在熱水中會不可逆地水解，或變性形成一種水溶性的明膠。

英文....	The fibrous, extracellular matrix protein in skin, muscles, tendons, ligaments, and bone. Collagen is composed of repeating units of glycine-proline-hydroxyproline that form linear polypeptide chains; three chains are then twisted and interlocked with hydrogen bonding to form a rigid helix structure. Collagen-containing materials, such as hides, bones and fish, have been used to make animal glues since ancient times. Collagen will irreversibly hydrolyze, or denature, in hot water, forming a water-soluble gelatin.
荷蘭語....	Het extracellulaire matrixeiwit in bindweefsel. Onelastische eiwitgroepen die aanwezig zijn in pezen, ligamenten, huidbindweefsel, tandbeen, kraakbeen en botten. Wordt gebruikt in gelatine en dierlijke lijm.
西班牙語....	Proteína de la matriz extracelular en el tejido conectivo.
