question and answer 100% correct
What is the monomeric unit of Amino Acids
polypeptides?
How many varieties of amino acids are 20
there?
What bond is formed between the Peptide bonds
monomers of the polypeptide?
What is the general structure of an amino A polypeptide is a polymer of amino acids. Each polypeptide
acid? has a unique linear sequence of amino acids, with a carboxyl
end (C-terminus) and an amino end (N-terminus).
What parts are common to all amino acids? A hydrogen, an amino group, and a carboxyl group
What is the part of the amino acid that A R-Group
varies?
How are amino acids grouped? ...
, Why are amino acids called "acids?" They all contain the carboxyl group (-CO2H), which is acidic.
What parts of the amino acids are ...
joined with the peptide bond?
In what conditions does the carboxyl ...
group (-COOH) ionize to (-COO-)?
What is the difference between a Proteins are composed of α-amino acids linked together
polypeptide and a protein? by peptide bonds into polypeptide chains. An amino
acid is characterized by an amino group (-NH2) and a
carboxylic acid group (-COOH) linked to a carbon,
known as the α-carbon.
What is meant by "C-terminus" and There's an amine group on one end of the protein and a
"N-terminus?" carboxyl group on the other. They call the end with the
amine on it the "N terminus" because the chemical
formula for amine is NH2 while the end with the
carboxyl group on it is named the "C terminal" because
the chemical formula of a carboxyl is CH2. The N terminus
is the end that amino acids are added onto when mRNA
is translated in protein synthesis.
What level of protein structure do α-helices Secondary structure
and β-pleated sheets form?
What type of bonds do α-helices and Hydrogen Bonds
β-pleated sheets depend on?
3 dimensional structure depends on Interactions among various side chains (R groups).
interactions between the R groups, what
type of interactions contribute to tertiary
structure?
What is denaturation and what causes it? A process in which proteins or nucleic acids lose the
quaternary structure, tertiary structure and secondary
structure which is present in their native state. Alterations
in pH, salt concentration, temperature, or other
environmental factors can cause a protein to unravel.
Folding is assisted by a group of Chaperonins
proteins call _.
Why is misfolding a problem? They can lead to diseases such as Alzheimer's, Parkinson's,
and mad cow disease.
What are the 2 major nucleic acids? 1. Deoxyribonucleic Acid (DNA)
2.Ribonucleic Acid (RNA)
What is the monomeric unit of nucleic acid? Nucleotides
What sugar is used in RNA? Ribose
