Lecture 6: proteins Flashcards
proteins
sequences of amino acids held together by peptide bonds
peptide bonds
bonds that form between amino acid monomers
enzymes
a type of protein that makes or breaks specific covalent bonds
What element is found proteins that is absent in the CHOs and lipids?
nitrogen
what element is found in proteins that is not found in DNA?
- sulfur
* phosphorus is found in DNA
which bonds are created during the primary structure of proteins?
peptide bonds
which maintains the secondary structure of a protein?
hydrogen bonds between carboxyl and amino groups
Bonds in tertiary structure
hydrogen bonds, ionic bonds, disulfide bonds, hydrophobic bonds
What molecule codes for the primary structure of protein?
sequence of DNA
Cellulose
- structural carbohydrate for plants
- made up of beta glucose monomers
- structure stability due to hydrogen bonds
- found in plant cell walls
Collagen
- structural protein in animals
- made up of amino acids
- structure stability due to hydrogen bonds
At which level are interactions between the side chains (R groups) most important?
tertiary structure
