膠原

膠原蛋白是動物結締組織中的主要蛋白質，也是哺乳動物中含量最高的蛋白質，約佔全身蛋白質含量的25％至35％。 它天然存在於後生動物中，包括海綿。 在肌肉組織中，它是子宮內膜的主要成分。 膠原蛋白構成肌肉組織的1％到2％，佔強壯的肌腱肌肉重量的6％。 食品和工業中使用的明膠來源於膠原蛋白的部分水解。
Collagen is one of the long, fibrous structural proteins whose functions are quite different from those of globular proteins such as enzymes.膠原蛋白是長纖維結構蛋白之一，其功能與球狀蛋白（例如酶）的功能完全不同。 Tough bundles of collagen called collagen fibers are a major component of the extracellular matrix that supports most tissues and gives cells structure from the outside, but collagen is also found inside certain cells.堅韌的膠原蛋白束（稱為膠原蛋白纖維）是細胞外基質的主要成分，支持大多數組織並從外部提供細胞結構，但在某些細胞內部也發現膠原蛋白。 Collagen has great tensile strength, and is the main component of fascia, cartilage, ligaments, tendons, bone and skin.膠原蛋白具有很高的抗張強度，是筋膜，軟骨，韌帶，肌腱，骨骼和皮膚的主要成分。 Along with soft keratin, it is responsible for skin strength and elasticity, and its degradation leads to wrinkles that accompany aging.它與柔軟的角蛋白一起，負責皮膚的強度和彈性，其降解導致皺紋並伴隨衰老。 It strengthens blood vessels and plays a role in tissue development.它增強血管並在組織發育中起作用。 It is present in the cornea and lens of the eye in crystalline form.它以晶體形式存在於眼角膜和晶狀體中。 It is also used in cosmetic surgery and burns surgery.它也用於整容手術和燒傷手術。 Hydrolyzed collagen can play an important role in weight management, as a protein, it can be advantageously used for its satiating power.水解膠原蛋白在體重管理中起著重要的作用，它是一種蛋白質，具有令人滿意的飽足力，因此可以被有利地使用。
