You may be wondering what this Cysteine injection is. Sometimes when we are sick and hospitalized, we are unable to eat. At such times, the body has to be given the necessary nutrition through a vein. Cysteine is a very important ingredient that can be contained in a nutritional solution given at such times. Let's talk about this simply today.
Simply put, what is Cysteine?
Cysteine is an amino acid that is essential for our body. Think of our body as a house. The bricks used to build that house are proteins. These amino acids are one of the ingredients used to build those bricks called proteins.
So, when someone is unable to eat by mouth, after surgery, or in a situation like a premature baby, this cysteine is added to nutritional solutions (like saline) given through a vein to help the body make the proteins it needs. In other words, it acts as a protein supplement .
