Glutathione is protein which contain how many amino acids:

## **Core Concept**
Glutathione is a crucial antioxidant molecule found in cells, composed of three amino acids. It plays a significant role in maintaining cellular redox balance and protecting against oxidative stress.

## **Why the Correct Answer is Right**
Glutathione is a tripeptide, meaning it is made up of three amino acids: glutamic acid, cysteine, and glycine. The sequence of these amino acids in glutathione is γ-glutamylcysteine-glycine. This unique composition allows glutathione to perform its antioxidant functions, including neutralizing free radicals and detoxifying harmful substances.

## **Why Each Wrong Option is Incorrect**
* **Option A:** This option suggests glutathione is made of a single amino acid, which is incorrect because glutathione is a tripeptide.
* **Option B:** This option suggests glutathione is made of two amino acids, which is incorrect because it specifically consists of three amino acids.
* **Option D:** This option suggests glutathione is made of four amino acids, which is incorrect because it has only three.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that glutathione's structure, being a tripeptide, is crucial for its function. It is involved in various cellular processes, including the detoxification of drugs and the maintenance of the cellular redox state.

## **Correct Answer:** . Glutathione contains 3 amino acids.
