What are monomeric units?
Answer
Monomeric units are the small, repeating molecular building blocks that are linked together by covalent bonds (polymerization) to form large polymeric biomolecules.
- Monosaccharides (e.g., glucose, fructose) are monomeric units of polysaccharides like starch and cellulose.
- Amino acids (20 types) are monomeric units of proteins (polypeptides).
- Nucleotides are monomeric units of nucleic acids (DNA and RNA).
- Fatty acids and glycerol are building blocks (monomers) of fats and phospholipids.
- Isoprene units are monomers of terpenes and steroids.
