Lithium ion inhibits the synthesis of inositol trisphosphate by inhibiting a reaction in the breakdown of inositol trisphosphate. Explain this apparent paradox.
[1-14C]Ribose-5-phosphate is incubated with a mixture of purified transketolase, transaldolase, phosphopentose isomerase, phosphopentose epimerase, and glyceraldehyde-3-phosphate. Predict the distribution of radioactivity in the erythrose-4-phosphate and fructose-6-phosphate that are formed in this mixture.
The glycerol 3-phosphate required for the synthesis of glycerophospholipids can be synthesized from a glycolytic intermediate. Propose a reaction sequence for this conversion

- Homocystinuria 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[1-14C]Ribose 5-phosphate is incubated with a mixture of purified transketolase, transaldolase, phosphopentose isomerase, phosphopentose epimerase, and glyceraldehyde 3-phosphate.

- Sphingosine 1-phosphate (SPP) is important for cell survival. The synthesis of SPP from sphingosine and ATP is catalyzed by the enzyme sphingosine kinase. An understanding of the kinetics of the sphingosine kinase reaction may be important in the development of drugs to treat cancer. The velocity of the sphingosine kinase reaction was measured in the presence and absence of threo-sphingosine, a stereoisomer of sphingosine that inhibits the enzyme.
