1. What's a cysteine?

Cysteine, more specifically α-amino-β-thiolopropionic acid, is a chemical compound belonging to a group of 22 basic branched-chain amino acids. Cystine is endogenous in nature, it should be included in the list of substances necessary for the proper functioning of our bodies. A characteristic feature is the presence of a thiolic group responsible for the formation of disiar bridges that act on the third-order structure of proteins. Together with homocysteine and methionine, it forms a sulfuric amino acid group.

2. Cysteine and its properties

Cysteine belongs to the group of reactive amino acids, which means that it has a strong effect on the detoxification and regenerative processes of the human body. One of the basic functions of α-amino-β-thiolopropionic acid is its role in the synthesis of glutathione one of the strongest and most effective antioxidants. In association with glycine and glutamine, it is also a basic antioxidant in our body. It is worth mentioning that cysteine also has a powerful cleansing effect.

3. Symptoms of deficiency

Cysteine is mainly present in the protein structures found in the basic products of our fibers the skin, hair and nails mentioned above. A deficiency of cysteine, which is one of the substrates for the synthesis of chondroitinosauric acid, will be manifested primarily by a decrease in the strength of these structures. This can result in easily broken and broken bones, faster degradation and greater nail plate fracture, as well as corneal disorders.

4. It's a performance

Cysteine is an amino acid, but it is in vain to look for it in the market of dietary supplements as a standalone preparation. This compound is most commonly found in various amino acid matrices such as BCAA, EAA or SAA products. In most cases, these are supplements aimed at intensifying regenerative and purifying processes, as well as contributing to the intensification of anabolic conversions. It is equally common as an ingredient in skin and hair cosmetics that contain 1% and 4% of this amino acid respectively. Speaking of natural sources of amino acids, attention should first be paid to high-fat products.
