Collagen

Collagen refers to the group of primary structural proteins necessary for the connective tissues, such as skin and cartilage. 

It is a crucial protein group as it makes up approximately one-third of all the protein present in the human body. There are 28 different types of Collagen; thus, it can be divided into five classes to understand it better.  

Most of the Collagen in our body is Type 1. It is present in skin, organic parts of bones, tendons, and internal organs. The remaining Collagen is found in: 

• Type 2: This type of Collagen is found in the cartilage. 

• Type 3: It is mostly found in the bone marrow and lymphoid tissues. 
• Type 4: It is mostly found in the basement membrane (thin sheets of Collagen that surround most types of tissues). 
• Type 5: This is something found on the surface of the cells or on the hair.  

Therefore, it is a crucial protein that helps heal skin and improve the texture of the same.
