BIO 260 Chapter 5-Translation
1. Amino Acid: (aka residue)- protein building block
2. 9: How many essential amino acids are there?
3. 1. zCarbon center
2. Amino Group (+);
3. Carboxyl Group (-) f amino acids
4. R-group; properties vary (aka side chain; Radical group).: The 4 parts o
identity gives each
4. Side Chains: Portion of an amino acid not involved in forming peptide bonds; its chemical
amino acid its unique properties.
- shape the protein/peptide structure
- vary
5. protein shape determines its 'job': what is meant by the phrase "form determines function"?
1/4
, 6. Primary Structure of a Protein: its sequence of amino acids
7. Secondary Structure of a Protein: Interaction between amino acids which causes the primary
structure to fold into this.
- includes z- helices and β- sheets
8. z- helix: secondary structure formed by H bonds between amino acids 4 positions away from each other
9. β- sheet: A recurring structural pattern within proteins with a pleated appearance.
10. Tertiary Structure of Proteins: Secondary structure folds further into this
11. Quaternary Structure of Proteins: Two or more polypeptide chains may asso
ciate, creating this
structure
12. Domain: group of amino acids form a functional unit
13. Codon: a triplet of nucleotides (in DNA or RNA), which together code form an amino acid.
