Micromolecules (Acid-soluble Pool)
Defines micromolecules as compounds with molecular weights less than 1000 Da, found in the acid-soluble fraction, including amino acids, sugars, and nucleotides.
What is Micromolecules (Acid-soluble Pool)?
Small organic molecules with molecular weights generally less than 1000 Daltons, found in the acid-soluble fraction of biological tissues.
Key points
- Define micromolecules and the acid-soluble pool.
- Identify the types of molecules present in the acid-soluble pool.
- Understand the process of separating micromolecules from macromolecules.
- Recognize the significance of micromolecules in biological systems.
Common exam trap
Confusing micromolecules with macromolecules.
