41. In chemical terms, agar is a polymer made up of subunits of the sugar galactose . 42. You're already immune to alpha-1, 3-galactosyl-galactose bonds. 43. After lactose is cleaved it actually forms glucose and galactose ( easily converted to glucose ). 44. In contrast, a galactosemic individual who consumes galactose can cause permanent damage to their bodies. 45. These are formed by the repetitive addition of galactose and N-acetyl-glucosamine units. 46. This enzyme participates in galactose metabolism. 47. First, galactose mutarotase converts ?-D-galactose to ?-D-galactose. 48. First, galactose mutarotase converts ?-D-galactose to ?-D-galactose. 49. First, galactose mutarotase converts ?-D-galactose to ?-D-galactose . 50. Either a galactose or a glucose can be added to a hydroxyl on the lipid ceramide.
