Fibrillar Precollagen

**PreCollagen fibrils**

**Introduction** Pre-Collagen fibrils (fibrils) are fibrous protein structures found in the skin, ligaments, muscles and other tissues of the body. They play an important role in maintaining the elasticity and strength of tissues, as well as in protecting the body from various damages. Fibrils are composed of three types of proteins - collagen, elastin and fibronectin. Collagen and elastin are responsible for the strength and elasticity of tissues, respectively, and fibronectin binds these two proteins together and ensures their proper organization.

Currently, more and more research is being developed in the field of fibrils. However, many questions about their structure, function and mechanism of action still remain open. In this article we will look at the main aspects of studying PreCollagen fibrils.

**Processes that Control Fibril Formation** Fibril formation is accomplished through processes involving the formation of chains of three different tyrosine kinases, the binding of calcium citrate to the acidic proline and lysine residues on the cell surface and matrix, the formation of a polypeptide chain, and the initiation of cross-linking between chains.
