Macromolecules are polymers that are made from linking building blocks ( ) with bonds by , and can disassemble by .
Carbohydrates are and serve as fuel and building material.
- Monosaccharides such as glucose are sugar monomers and can be linked to form .
- consist of two monosaccharides.
- contain many monosaccharide monomers.
are mostly neutral hydrocarbons and thus are .
- Fats can be with no double bonds in the hydrocarbon chains, or with double bonds.
- Two important classes of in cells are phospholipids and steroids.
Proteins consist of one or more chains, which are polymers of amino acids.
- An is a protein that acts as a , speeding up chemical reactions.
Nucleic acid polymers called are made of monomers.
- DNA is usually composed of two polynucleotide strands wound around each other in a helix.
