cysteeniin
Cysteeniin is a non-essential amino acid, meaning the human body can synthesize it and does not strictly require it from the diet. It plays a crucial role in protein synthesis and metabolism. Cysteine is characterized by its sulfur-containing side chain, which is unique among the common amino acids. This sulfur atom is important for the formation of disulfide bonds, which are vital for the three-dimensional structure and stability of many proteins.
Two molecules of cysteine can form a disulfide bond to create cystine, a more oxidized form of
Dietary sources of cysteine include protein-rich foods such as meat, poultry, eggs, dairy products, and legumes.
