I just noticed cysteine is spelled as "cystine," which is the dimer form of cysteine in living tissues (look at me!). Anyway, not a big thing but maybe you'll fix it when you have time. Thanks!
Good eye! This is the form of cysteine reported by the USDA - it's much more stable than cysteine on its own and therefore much easier to measure, though I can't quite say why they don't just call it cysteine. The number reported takes into account the amount of cysteine available.
