Cysteine, molecular model
Cysteine. Molecular model of the amino acid cysteine. Its chemical formula is C3.H7.N.O2.S. Atoms are represented as rods and are colour- coded: carbon (blue), hydrogen (gold), nitrogen (dark blue), oxygen (red) and sulphur (yellow). Amino acids are the building blocks of proteins. Cysteine is a non-essential amino acid. It can be synthesised by the body and so does not need to come from the diet. Cysteine is an important structural and functional component of many enzymes (proteins that catalyse metabolic reactions). For example, it allows coenzyme proteins to bind to metal cofactor molecules. Without this binding ability, the coenzyme proteins are unable to function as enzymes

EDITORS COMMENTS
This print showcases the intricate molecular model of cysteine, an essential amino acid. The composition elegantly depicts the chemical formula C3. H7. N. O2. S, with each atom represented as color-coded rods. Carbon appears in a striking blue hue, hydrogen in shimmering gold, nitrogen in deep blue, oxygen in vibrant red, and sulphur in a radiant yellow shade. Amino acids serve as the fundamental building blocks of proteins, and cysteine holds a special place among them. Remarkably, this particular amino acid is non-essential since our bodies can synthesize it internally without relying on dietary sources. Its significance lies not only in its structural role but also as a functional component within numerous enzymes that catalyze vital metabolic reactions. One notable function of cysteine is enabling coenzyme proteins to bind with metal cofactor molecules. This binding ability allows these coenzymes to fulfill their enzymatic functions effectively. Without this crucial interaction between cysteine and metal cofactors, these coenzymes would be rendered ineffective. The artistic representation presented here beautifully captures the essence of this complex biochemical compound. It serves as a reminder of the intricacies found within nature's building blocks and highlights the importance of understanding such molecular structures for scientific advancements across various fields like biochemistry and medicine.
