The anomeric carbon in glucose is carbon number:

  1. 1
  2. 2

  4. 6
Show answer and explanation

Correct answer: 1

In glucose, the C1 aldehyde carbon becomes the anomeric carbon when the open chain cyclizes into a ring. It is unique because it can adopt two configurations — alpha (axial OH) and beta (equatorial OH) — which differ in optical and biochemical properties.
