Abstract

The invention discloses a preparation method of crocodile collagen, which can improve the added value of the production and processing of crocodiles, reduce environmental pollution and create high economic and social benefit. Pharmacodynamic experiments show that the crocodile collagen has obvious effects in terms of aging resistance, tissue repair, wound healing promotion and immunity enhancement.

Description

field of invention [0001] The invention relates to a crocodile collagen and a preparation method and use thereof. Background technique [0002] Collagen is a white, opaque, unbranched, fibrous protein with a molecule containing sugar and a large amount of glycine, proline and hydroxyproline, mainly found in animal tendons, ligaments, cartilage, skin and other connective tissues. It accounts for 25-33% of the total protein content in the human body or other animals. It has the functions of supporting organs and protecting the human body. Different types of collagen in different tissues are extracted from animals, and their functions and effects are also different. With the development of biochemistry, people's understanding of collagen has gradually improved. Now it has been confirmed that collagen, like immunoglobulin, is rich in diversity and specificity in tissue distribution, and is a functional protein related to the functions of various tissues and organs. . Alligato...
