Breaking down macromolecules are done by _________ reactions.
Proteins are polymers of
Polysaccharides (starch) are polymers of:
Nucleic Acids (DNA & RNA) are polymers of:
____ _____ determine properties of particular amino acids.
What are the 4 amino acid side groups?
- Serine (S)- polar (Hydrophilic)
- Aspartate (D)- Acidic (- charge)
- Lysine (K)- Basic (+ charge)
- Valine (V)- Non-polar (Hydrophobic)

Is a peptide bond polar covalent, nonpolar covalent or ionic?
Covalent Polar Bond
Levels of Protein Structure are:
- Primary structure
- Secondary structure
- Tertiary structure
- Quaternary structure
what structure is the sequence of amino acids
What structure shows how primary sequence is folded?
What structure is the 3-D shape of the protein?
What structures shows how subunits are arranged?
What determine final protein structure and characteristics?
The sequence of Amino Acids.
Amino acid chain folds due to ______ bonding between amino acids
What are the two types of Secondary protein structures?
- 1. Alpha Helix (spiral)
- 2. Beta pleated sheet (hairpin)
