Cysteine Micro Molecule

This is a framework molecular model kit of the Amino Acid Cysteine.  This is part of our new line of MicroMolecules that are one half the scale of our regular framework molecular models at 0.5 inch per 1 Angstrom. The finished molecule literally fits in the palm of your hand.  No assembly required. Stay tuned for the release of all of the amino acids and other series soon to come.

Cysteinyl is a residue in high-protein foods. Although classified as a nonessential amino acid, in rare cases, cysteine may be essential for infants, the elderly, and individuals with certain metabolic diseases or who suffer from malabsorption syndromes. Cysteine can usually be synthesized by the human body under normal physiological conditions if a sufficient quantity of methionine is available.

The majority of l-cysteine is obtained industrially by hydrolysis of animal materials, such as poultry feathers or hog hair. Despite widespread belief otherwise, little evidence shows that human hair is used as a source material and its use is explicitly banned for food additives and cosmetic products in the European Union.

CAUTION: THESE MOLECULES CONTAIN MANY SMALL PARTS NOT SUITABLE FOR CHILDREN UNDER 5 YEARS OF AGE.
