Collagen - Wikipedia
网页The synthesis of collagen occurs inside and outside of a cell. The formation of collagen which results in fibrillary collagen (most common form) is discussed here. Meshwork collagen, which is often involved in the formation of filtration systems, is another common form of collagen.

网页2023年9月4日 · Collagen is protein molecules made up of amino acids. It provides structural support to the extracellular space of connective tissues. Due to its rigidity and resistance to stretching, it is the perfect matrix for skin, tendons, bones, and ligaments. Collagen can be further divided into several groups depending on the type of structures they form.
