What amino acids can be deaminated directly?
Amino acid serine and threonine
Serine » pyruvate and NH4
Threonine reanimated to alpha ketobutyric acid
7. What will happen to the carbon skeleton of the deaminated amino acids when excessive protein and calories are consumed? a. It is metabolized by the liver to urea b. They will be metabolized to fat c. They will be metabolized to ketones
2) A) Amino acids such as Phe and Val are not known to participate directly in acid-base or covalent catalysis. Explain why B) Mutating a Phe and Val can still have dramatic effects on enzyme activity. Why?

Fill in the Blanks In the biosynthesis or ornithine, the amino acid___________ is oxidatively deaminated to provide its nitrogen.
Additional energy can be provided and body fat can be made when amino acids are converted to acetyl COA Some amino acids enter the TCA cycle directly and therefore, are allowed to continue in the metabolic cycle to generate energy and glucose The availability of nitrogen allows the body to use acetyl COA and glycerol to make some non-essential amino acids.

How are the correct amino acids brought to the rib... How are the corect amino acids brought to the ribosomes for protein synthesis? The amino acids are synthesized directly at the ribosomes by the hydrolysis of dietary protein. OAmino acids are carried in the interior of the DNA double helix, then carried to the ribosomes. OAcetyl-CoA carries the amino acids that match the codon on DNA. O Transfer RNA molecules, whose anticodon loop contains the complementary sequence of an MRNA...
after crossing from the enterocytes into the bloodstream amino acids travel directly to body cells that need them
Question 2 (1 point) Amino acids can be classified as A. Hydrophobic amino acids with nonpolar R groups B. Polar amino acids with neutral R groups but the charge is not evenly distributed C. Positively charged amino acids with R groups that have positive charge at physiological pH. D. Negatively charged amino acids with R groups that have a negative charge at physiological pH. How would the amino acid alanine be classified? Think through your reasoning. L-Alanine H2N-CHC-OH CH3
Amino acids can be classified by the:a. number of carbon–carbon double bonds in their fatty acids.b. number of peptide bonds they can form.c. characteristics of their side chains or "R" groups.d. number of monosaccharides they contain.e. number of disulfide bridges they can form.
A student used chromatography to separate a mixture of amino acids. Since amino acids are invisible on the paper, what can be done to make them visible?
What are amino acids?
