Amino Acids And Peptides Flashcards
What are proteins used for ?
Immunological responses
Muscle skin ligaments hair
Form structural components of animals
What is the simplest amino acid?
Glycine
Amino and acid/carboxyl group of amino acids
The amino group has two H and a N
The acid group has a doble C to O bond and a C to OH bond
What is the bond formed between two amino acids?
Peptide bond
Were does the peptide bond form?
Between the OH on the acid group and the H on the amino group
What breaks down polypeptides ?
The enzyme protease
What does the amino group act as?
A base ( proton acceptor)
What does the carboxyl group act as?
An acid (proton donor)
Amphoteric
Both Acidic and baseic
Why do amino acids work as a buffer?
They resist attempts to change ph
Primary structure of proteins
20 amino acids at every point there are 20 alternatives
Chains made of 100 amino acids
Secondary structure of amino acids
Chain twists and some twist into alpha helix with 36 amino acids every 10 turns
Held together by H bonfs
Beta pleated sheets
Fold into zigzag
H bond further down hold it together
How are tertiary structures formed?
When coils and pleats fold forming a precise shape
This forms a super coiled or spherical structure
How are quaternary structures formed
When more than one polypeptide chain bonds
Held together by bonds that hold tertiary structure
