Cystine is essentially two molecules of cysteine just like how homocystine is essentially two molecules of homocysteine


In cystinuria, there's defective excretion of dibasic amino acids which are cysteine, ornithine, lysine, and arginine

So as cysteine accumulates, two molecules get attached via disulphide bond and cystine forms and accumulates which may lead to formation of hexagonal calculi in the urine

what u said its a matter of perfection except that according to my knowlage the cystine stones doesn't form a stag horn it form a hexagonal cystine crystals.. the stag horn formed by Magnesium-amonium-phosphate (Struvite) Stones

am i right ?!:confused:
