Which root refers to the protein albumin?

• A. Glycos/o
• B. Bi/o
• C. Albumin/o
• D. Crypt/o

Answer: (C)

The combining form for the protein albumin is albumin/o. Albumin is a major plasma protein produced by the liver, and when forming terms that relate to this protein, the form albumin/o is used (for example, albuminemia or albuminuria). The other roots point to different concepts: glycos/o (or glyco-) refers to sugar, bi/o relates to life, and crypt/o means hidden. Thus albumin/o is the appropriate root for this protein.
