Difference Between Collagen and Gelatine

Thekey difference在胶原蛋白和明胶之间胶原蛋白是一种结构protein在皮肤和其他connective tissues动物，而明胶是不可逆转的水解胶原蛋白。

Collagen is the most abundant protein in mammals. Therefore, it contains about 25 – 35% of total body proteins. It has many applications in medicine for treating disorders regarding connective tissues. Gelatine is a common jelling agent that has many applications in food industry. We can produce this compound from collagen that we obtain from body parts of animals such as cattle, chicken, and pigs that are domesticated.

什么是胶原蛋白？

Collagen is the main structural protein found in skin and other connective tissues. It also is the most abundant protein in mammals (25 – 35% of body protein). Furthermore, this compound forms form the combination of amino acids. We can recognize the chemical structure of this compound as a triple-helicase which forms elongated fibrils. The most common tissues of our body where we can find collagen are in fibrous tissues such as tendons, ligaments, and skin.

The nature of collagen can be either rigid or compliant. But sometimes, it may have a rigid to compliant nature depending on the degree of mineralization. Ex: collagen is in rigid form, in bones, compliant at tendons and intermediate at cartilage. Being a structural protein, this compound has many medical uses in treating disorders of bones and skin. It is widely used in the purified form for cosmetic surgical treatments as well.

什么是明胶？

明胶是一种源自胶原蛋白的无色和半透明的食物。这种化合物从动物的各个身体部位，即皮肤，骨骼，鸡，鸡，猪，鱼类等。这种化合物在干燥时脆弱。我们可以通过胶原蛋白的不可逆水解产生这种化合物。它在食品工业中作为杰林代理人以及制药行业的药物生产有很多用途。此外，它在摄影，维生素胶囊的生产以及化妆品制造中也很有用。

This compound has proteins andpeptides. These proteins and peptides hydrolyze partially to form gelatine. There, the natural molecular bonds between collagen strands are broken down to rearrange, forming gelatine. This compound is available as a dry powder in the market. It readily dissolves in hot/boiling water and sets to form a gel when cooling down. But if we dissolve it in cold water, it does not dissolve that much.

此外,这种化合物溶解在许多极地solvents. When dissolved, it is a highly viscoelastic liquid. It is a best-selling jelling agent in cooking. In addition, theater lightening equipment also uses this compound as color gels to change the color of the beam. Apart from that, cosmetics also contain this compound in the name “hydrolyzed collagen”.

胶原蛋白和明胶有什么区别？

Collagen is the main structural protein found in skin and other connective tissues. It is a naturally occurring protein. This compound has a triple-helical structure that forms elongated fibrils. Gelatine is a colorless and translucent food derived from collagen. We can produce this compound from collagen via irreversible hydrolysis. Moreover, it forms by breaking down and rearranging the molecular bonds between the protein and peptides of collagen. This is the main difference between collagen and gelatine.

摘要 - 胶原蛋白与明胶

Collagen is a protein. it has many uses in medicine for treating disorders of body parts because it is the main structural protein of our connective tissues. Gelatine, on the other hand, is a product that we can produce from collagen. The difference between collagen and gelatine is that collagen is a structural protein found in skin and other connective tissues of animals whereas gelatine is irreversibly hydrolyzed collagen.
