cys·tine

 (sĭs′tēn′)
n.
A white crystalline amino acid, C6H12N2O4S2, that is formed from the disulfide linkage of two cysteines during the folding of many proteins, especially keratin, and stabilizes the tertiary structure of the protein.

[From its discovery in bladder stones.]

cystine

(ˈsɪstiːn; -tɪn)
n
(Biochemistry) a sulphur-containing amino acid present in proteins: yields two molecules of cysteine on reduction. Formula: HOOCCH(NH2)CH2SSCH2CH(NH2)COOH
[C19: see cysto- (bladder), -ine2; named from its being discovered in a type of urinary calculus]

cys•tine

(ˈsɪs tin, -tɪn)

n.
a crystalline amino acid, C6H12O4N2S2, occurring in most proteins, esp. the keratins.
[1835–45; < Greek kýst(is) bladder, cyst + -ine2; so called because found in the bladder]

Horizon Pharma plc announced the launch of Cystinosis United, an initiative created for people living with nephropathic cystinosis, a rare genetic metabolic disease that causes the amino acid cystine to accumulate in all organs of the body.
Methionine and cystine are the first-limiting amino acids for fur animals, which have a significant effect on fur growth and quality (Dahlman et al.
We found statistically significant correlations between increased resistance to 5-fluorocytosine and higher activity of acid phosphatase; increased resistance to ketoconazole and higher activity of beta-glucuronidase; increased resistance to miconazole and higher activity of beta-glucosidase; increased resistance to itraconazole and higher activity of N-acetyl-beta-D-glucosidase, as well as increased susceptibility to itraconazole and higher enzymatic activity of cystine arylamidase and naphthyl phosphohydrolase.
Cystinosis is a rare metabolic disease with autosomal recessive inheritance, (1) characterized by the accumulation of cystine crystals in various tissues including the kidneys, bone marrow, pancreas, thyroid, muscle, brain, and eyes.
After percutaneous nephrolithotomy, stone analysis found a calcium oxalate (CaOX) stone in patient-1 and a cystine stone in patient-2.
Each experimental diet was supplemented with crystalline methionine (Met), lysine (Lys), tryptophan (Trp), threonine (Thr), isoleucine (Ile), valine (Val), cystine (Cys), and arginine (Arg) to meet the digestible amino acids (Dig AAs) profile [12].
Cystinuria is an autosomal recessive disorder in which the kidney, due to a genetic defect in the cystine transporter, is unable to reabsorb cystine in the proximal tubule, resulting in urinary hyperexcretion of amino acids cystine, ornithine, lysine, and arginine (COLA).
Cystine crystal deposits start in the cornea and lead to increased sensitivity to light (photophobia) and corneal surface deterioration (keratopathy).
Pharmaceutical scientists in Sunderland have been awarded PS150,000 by the Cystinosis Foundation (CF) UK to support their research, which they hope will help them transform treatment for cystinosis, a devastating illness which occurs when the body becomes unable to process cystine, an amino acid.
Cystine stones result from a rare genetic disorder that causes cystine -- an amino acid, one of the building blocks of protein--to leak through the kidneys and into the urine to form crystals.
