Main Lesson Flashcards
Naturally occurring, unbranched polymer in which the monomer units are amino acid
Protein
Is an amino acid in which the amino group, the carboxyl group and the hydrogen atom are attached to the -carbon ato
alpha-amino acid
What are the classification of amino acids? Explain.
- Nonpolar amino acid
- Polar neutral
- Polar basic
- Polar acidic
Is an amino acid where side chain is not free but attached to the amino group
Proline
What is nonpoar amino acid?
- Nonpolar side chain
- G,A,V,L,I,P,F,M,W
What is polar neutral?
- Side chain that is polar but neutral
- S,C,N,T,Q,Y
What is polar basic?
- second amino group being part of the side chain
- H,K,R
What is polar acidic?
- Second carboxyl group being part of the side chain.
- D,E
What are the two types of amino acids?
Essential and Non-essential
The human body cannot synthesize it in adequate amount, it is needed for protein synthesis
Essential amino acid
What is essential for children’s growth but not for adult?
Arg - arginine
Letters for essential amino acids?
R*,H,M,I,L,K,W,T,F,V
Letters for non-essential amino acids
- C,A,N,D,E,Y,S,Q,G,P
Synthesized by the body
Non-essential amino acids
Protein that contains all of the essential amino acids? This may or not may contain all of the non-essential amino acids.
Complete dietary protein
Is a protein that does not contain adequate amounts.
Incomplete dietary protein
Is an essential amino acid that is missing
Limiting amino acid
Are two or more incomplete dietary protein
Complementary dietary proteins
Are formed by a biochemical reaction that extracts a water molecule
Peptide bonds
Another term for peptide bonds?
Amide bond
What are the types of peptide bonds?
- Dipeptide - 2 or more amino acids
- tripeptide - 3 or more amino acids
- oligopeptide - 10 or 20 amino acids
- polypeptide - w longer unbranded chain of amino acids
What is the primary structure of a protein?
Amino acid sequence
How do proteins arrive at their final shapes?
- Protein folding
- Denaturation of proteins
- Role of chaperones in protein folding
