Structure of Amino Acids
This group is responsible for the unique properties of each amino acid.
What is the R group?
This reaction links amino acids by forming peptide bonds.
What is a condensation reaction?
This condition, caused by insufficient protein intake, can lead to fatigue and muscle loss.
What is protein malnutrition?
This structure results from the sequence of amino acids in a polypeptide chain.
What is the primary structure?
This term describes the unfolding of a protein due to high Questionerature or extreme pH.
What is denaturation?
The backbone of amino acids consists of this repeating pattern.
What is N-C-C?
These two types of secondary protein structures are stabilized by hydrogen bonds.
What are alpha helices and beta pleated sheets?
These proteins contain all nine essential amino acids.
What are complete proteins?
These amino acids tend to fold into the protein's interior because they are hydrophobic.
What are nonpolar amino acids?
This structure remains intact during denaturation because it involves covalent bonds
What is the primary structure?
This group in an amino acid contains a nitrogen atom bonded to two hydrogen atoms.
What is the amine group (NH2)?
This term describes proteins with a prosthetic group, like hemoglobin.
What are conjugated proteins?
Vegans must carefully combine foods to ensure they obtain these nutrients.
What are essential amino acids?
This type of bond forms between cysteine amino acids in the tertiary structure.
What is a disulfide bridge?
These cellular structures break down defective proteins into amino acids.
What are proteasomes?
This group in an amino acid contains a carbon atom double-bonded to oxygen and single-bonded to a hydroxyl group.
What is the carboxyl group (COOH)?
The three-dimensional structure of a protein results from interactions between these groups.
What are R groups?
This happens when the body begins digesting its own proteins during malnutrition.
What is muscle and organ breakdown?
Charged amino acids can form these bonds with oppositely charged amino acids.
What are ionic bonds?
High pH cause proteins to denature after this point is reached.
What is the optimum pH?
Amino acids differ from each other in this part of their structure.
What is the R group?
This is the process of folding a protein and chemically modifying it to become functional.
What is protein modification?
Examples of these proteins include nuts, seeds, and beans.
What are incomplete proteins?
Proteins with hydrophilic R groups tend to have these groups exposed on their surface.
What are polar R groups?
The process of breaking down and reusing amino acids to synthesize new proteins.
What is recycling by proteasomes?
