Question
Chapter 25, Problem 51P
Interpretation Introduction
Interpretation:
Biochemical defects and symptoms of Lesch-Nyhan syndrome are to be determined.
Concept introduction:
Lesch-Nyhan syndrome is an X-linked inherited disorder. It affects about 380,000 people across the globe. Due to this uric acid gets accumulated in the blood and urine, leading to hyperuricemia and hyperuricosuria. This also leads to gout and kidney problems.

- This question should be answered with two or three sentences using relevant biochemical vocabulary.arrow_forwardOrotic aciduria results when one of the enzyme activities of UMP synthetase is absent. This syndrome is characterized by large amounts of orotic acid in the blood and urine, megaloblastic anemia (characterized by large, immature , and dysfunctional red blood cells) and retarded growth. Suggest a possible treatment for this condition.arrow_forwardPKU Worksheet Read the following paragraph about a genetic disorder identified as an inborn error of metabolism. Illustrate your understanding of metabolic pathways and mutations by responding to the guiding questions. Please also use this link ( https://rarediseases.org/rare-diseases/phenylketonuria/ ) for more information. Phenylketonuria (PKU) is an inherited disorder that is identified as an inborn error of metabolism. It is easily detectable during the first days of life through newborn screening tests. A drop of the infant’s blood can determine the presence of the enzyme that is responsible for processing the essential amino acid phenylalanine. With normal enzyme activity, phenylalanine is converted to another amino acid (tyrosine), which is then utilized by the body to produce melanin (pigmentation in hair, skin, eyes), thyroid and other hormones. However, when the phenylalanine hydroxylase enzyme is absent or deficient, phenylalanine abnormally accumulates in the blood. A…arrow_forward

Suppose that you have the peptide Ala-Gly-Tyr-His-Leu and you treat it with FDNB and then 6M HCl. Draw the structures of all the products that you will have in solution (assume all reactions to go to completion).arrow_forwardIn some organisms, isoleucine can be synthesized in a multi-step procedure (a series of enzymatic reactions), beginning with a molecule of threonine. Keeping that in mind explain the experimental results below. Amount of endproduct Activity of threonine (isoleucine) deaminase None Low Medium High Very high High Moderate Very lowarrow_forward
- Using the biosynthesis of aminolevulinate (ALA) as an example, describe at least two techniques that can be used to elucidate detail of a biosynthetic pathway. Please keep brief - 5 sentences/dot points max.arrow_forwardGerhart and Pardee measured ATCase activity in the presence of a variety of purine and pyrimidine derivatives. Their results are presented in Table 2. What compound(s) were the most effective inhibitors? activators? Explain the significance of the metabolites that served as inhibitors or activators in the context of the biosynthetic pathway presented in Figure 1. Table 2: Effect of nitrogen bases, nucleosides and nucleotides on ATCase activity. *Indicates stimulation. (Based on Gerhart and Pardee, 1962.)

- The text describes a form of gout that results from HGPRT deficiency. Propose one or two additional enzyme abnormalities that might similarly lead to hyperuricemia.arrow_forwardSuggest a reason why the amino acids thyroxine and hydroxyproline are produced by posttranslational modification of the amino acids tyrosine and proline, respectively.arrow_forwardHomocystinuria is caused by a defect in cystathionine beta-synthase (or 13-synthase), which leads to an accumulation of homocysteine in the blood. This accumulation causes symptoms such as a tall, thin frame, flushed cheeks, and osteoporosis (thinning of the bones). These individuals should limit their intake of proteins that contain methionine, such as egg whites. Using your understanding of biochemistry, explain why people with Homocystinuria should not consume egg whites and other such proteins.arrow_forward
