Why do amino acids act as free radical scavengers and what is the mechanism?
Amino acids act as free radical scavengers due to their ability to donate hydrogen atoms to neutralize and stabilize free radicals by forming a stable radical intermediate. This mechanism involves the amino acid donating a hydrogen atom to the free radical, forming a new radical intermediate which is less reactive and no longer causes cellular damage.
Do all amino acids have R groups that are polar?
Yes, all amino acids have the same basic composition, though the r-groups causes the variation. There are 20 different amino acids.
What is primary structure of a protein and what causes it?
Primary structure of the protein is simply its amino acid sequence. It is the sequence in which amino acids are added during protein synthesis.
Can you Describe how the amino acids changes in the protein affect the function of the protein and how this causes disease?
Changes in amino acids can alter the protein's structure, affecting its function by disrupting its binding sites or enzyme activity, leading to disease. For example, in sickle cell anemia, a single amino acid change in hemoglobin causes it to form abnormal-shaped red blood cells, affecting oxygen transport and leading to the disease's symptoms.
What determines a protein's structure and a function?
A protein's structure is determined by its polarity. Sub-units have polar and non-polar parts. No-polar go in the inside and polar on the outside of the protein. They are attracted to each other and this is what causes the protein's complex patterns.
When present in the blood in elevated levels the amino acids can damage arterial walls and increase the risk of coronarty artery disease?
High levels of certain amino acids in the blood can lead to the formation of harmful byproducts that can damage the arterial walls, increasing the risk of coronary artery disease. It is important to maintain a balanced diet and monitor amino acid levels to reduce this risk.
When present in the blood in elevated levels the amino acid can damage arterial walls and increase the risk of coronary artery disease?

What intermediate would supply the carbon skeleton for synthesis of a five-carbon amino acid?
The intermediate that would supply the carbon skeleton for the synthesis of a five-carbon amino acid is alpha-ketoglutarate. This intermediate is a key component of the citric acid cycle and can donate its carbon atoms in various biosynthetic pathways for the production of amino acids through transamination reactions.
What is an aminolysis?
An aminolysis is an amino derivative of levulinic acid, especially 5-aminolevulinic acid, intermediate in the biosynthesis of porphyrin.
An intermediate substance in the synthesis of norepinephrine?
Dopamine is an intermediate substance in the synthesis of norepinephrine in the body. Tyrosine hydroxylase converts tyrosine to L-DOPA, which is then converted to dopamine by the enzyme aromatic L-amino acid decarboxylase before further conversion to norepinephrine.
What is an aminoadipic acid?
An aminoadipic acid is any amino derivative of adipic acid, especially α-aminoadipic acid which is an intermediate in the metabolism of lysine.
What amino acid component of aspartame or nutarsweet causes PKU?
phenylalanine

What is a Missence mutation?
A mutation that causes the code for the wrong amino acid (apexvs.com)
