Glycocholic acid

Manufactured by Yuanye Bio-Technology
Sourced in China

Glycocholic acid is a bile acid produced by the liver. It is a key component in the digestion and absorption of fats and fat-soluble vitamins. Glycocholic acid acts as an emulsifier, helping to break down large fat molecules into smaller ones that can be more easily absorbed by the body.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
