Quiz 1 Part 3 Review (Primary-Quaternary Structures) Flashcards
What is it called when bonds hold the amino acids together (Primary)?
It is called peptide bonds.
What are the linear amino acid sequence held together by (Primary)?
They are held by Amide Linkages.
How is the Primary Structure formed?
It is formed by the dehydration synthesis reaction between the amino group of one amino acid and the carboxyl group of another.
What are the two forms of folding (Secondary)?
–> Alpha Helix Formation (Curly)
–> Beta Pleated Sheet (Folded Paper)
How is the structure formed (Secondary)?
Both forms are held together bond due to hydrogen bonds between the amino acids.
How is the structure formed (Tertiary)?
The large scale folding is caused by bonding between the “R” group of amino acids.
What is sulfahydryl (Tertiary)?
They are hydrogen, ionic and disulfide bridges.
What is an enzyme (Tertiary)?
They are the hair fibers, and the globular shape.
How many polypeptide chains are folded together (Quaternary)?
2 or more polypeptide chains are folded together.
Primary Structure
A sequence of amino acids.
Secondary Structure
Occurs when amino acids are linked by hydrogen bonds.
Tertiary Structure
Certain attractions are present between Alpha and Pleated Sheets.
Quaternary Structure
Consists of more then one amino acid chain.
