Abstract

1. Purified ovomucin was isolated as an insoluble glycoprotein complex from thick egg white. 2. A homogeneous glycoprotein, designated α-ovomucin, of molecular weight 210000 and containing N-acetylglucosamine (6.7%, w/w), N-acetylgalactosamine (0.6%, w/w), galactose (1.8%, w/w), mannose (4.6%, w/w), N-acetylneuraminic acid (1.0%, w/w) and sulphate (0.7%, w/w), was isolated from preparations of reduced ovomucin by sedimentation equilibrium in a density gradient of caesium chloride formed in the presence of 4m-guanidine hydrochloride. 3. A carbohydrate-rich fraction, designated β-ovomucin (which is homogeneous by sedimentation-velocity analysis in 5m-guanidine hydrochloride but which is heterogeneous by analytical sedimentation equilibrium in a density gradient of caesium chloride in the presence of 4m-guanidine hydrochloride), containing N-acetylglucosamine (11.0%, w/w), N-acetylgalactosamine (8.7%, w/w), galactose (19.2%, w/w), mannose (4.1%, w/w), N-acetylneuraminic acid (13.8%, w/w) and sulphate (2.7%, w/w), was also obtained from preparations of reduced ovomucin by the density-gradient method. 4. Mild acid hydrolysis of the unfractionated ovomucin complex showed that N-acetylneuraminic acid occupied a terminal position of the oligosaccharide chains. 5. Alkaline β-elimination reactions with the unfractionated ovomucin complex indicated that N-acetylgalactosamine was linked by alkali-labile bonds to hydroxy amino acids.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
