21. Spot 42 RNA mediates discoordinate expression of the E . coli galactose operon. 22. Galactosylceramidase is an enzyme which removes galactose from ceramide derivatives ( galactocerebrosides ). 23. Adding galactose covers up that other sugar and protects the platelets from the macrophages. 24. The galactose is isomerized under alkaline conditions to D-tagatose by calcium hydroxide. 25. Galactose itself comes from the metabolism of the disaccharide lactose into glucose and galactose.26. Galactose itself comes from the metabolism of the disaccharide lactose into glucose and galactose . 27. This galactose monosaccharide can then be further elongated by the addition of a glucose. 28. Leguminous lectins consist of two or four bind either glucose, mannose or galactose . 29. Galactose oxidase belongs to the family of oxidoreductases.30. A remarkable feature of galactose oxidase is that it is a free radical enzyme.
