Basic knowledge review
- What is collagen?
Collagen is a natural protein, derived from the Greek word for “glue”.It is one of the most abundant proteins in mammals, accounting for 25%-35% of the body's total protein content. It is the fibrous connective tissue that connects our bodies together.Collagen consists of three long chains containing more than 1,000 amino acids wound to form a three-strand spiral. This unique structure can generate slender fibrils.Collagen has a high content of hydroxyproline, glycine and proline. This atypical amino acid structure has led us to discover 28 kinds of collagen, which are distributed in different parts of the body and are divided into several groups according to their composition, namely fibronectin (Type I, II, III, V, XI) or non-fibronectin (accounting for most of the other types).
Collagen and human history
Collagen has a long history of application in human history.Hundreds of years ago, people extracted collagen from beef or pig bone soup to make full use of various parts of the animal's body and avoid waste.Our ancestors quickly recognized the value of this protein.In the 12th century, the abbot and scholar Hildegard von Bingen recommended that people drink broth made from calf hooves (containing collagen) to relieve joint pain.Napoleon also believed it and supplied his troops with this nutritious drink.
Therefore, gelatin extracted from collagen has quickly been widely used, not only in food, but also in industry.With its unique physical and chemical properties and functions, collagen is widely used in many fields.
