A leuco compound comprises an antioxidant moiety covalently bonded to a leuco moiety. A laundry care composition comprises (a) at least one laundry care ingredient and (b) a leuco compound as described above. A method of treating a textile comprises the steps of (a) providing such a laundry care composition; (b) adding the laundry care composition to a liquid medium; (c) placing textile articles in the liquid medium; (d) optionally, rinsing the textile; and (e) drying the textile articles.

The presence of mild electrophiles, such as aldehydes, during the denaturation of glycoproteins or glycopeptides and subsequent enzymatic deglycosylation reduces artifacts in subsequent analyses of the glycans released from the glycoproteins or glycopeptides.
