Although most amino acids are used to synthesize proteins, they can meet other fates. Which of the statements are true about amino acids and metabolism? True about Amino Acids and Metabolism False about Amino Acids and Metabolism Answer Bank Amino acids are used to synthesize glucose only when blood glucose levels are high. When needed for energy, carbon skeletons from amino acids are oxidized through glycolysis. Nitrogen from amino acid metabolism is incorporated into urea and excreted in urine. Amino acids are converted to fatty acids when excess energy is consumed. Amino acids can be used to produce critical nitrogen-containing compounds. The liver is the main site of amino acid metabolism. After the removal of the amino group, the remaining carbon skeleton can be used for energy or the synthesis of glucose or fat.

Which of the following statements about amino acids is entirely true? There are 4 main types of amino acids_ Amino acids are the biomolecules that acidify the cell, to allow the cells to be broken down and recycled by the body: Amino acids chains make up the 'double helix' of DNA. Amino acids are typically found in the cytoplasm of the cell; where ribosomes incorporate them into protein chains.

Which three statements about amino acids are true? Use the amino acid structures for reference: Ser Thr Met Leu Gly Leucine has an overall charge at physiological pH (7.4). Methionine is a thiol. Ser and Thr are polar amino acids. The Leu side chain does not form hydrogen bonds with other amino acids. Threonine has more than one stereocenter (chiral center). The form of glycine used by the human body is D-glycine.
