Understanding the Occurrence of Natural Phospholipids In problem 1 (b) ill Chapter 8, you weft asked to draw all the possible phosphate-dylserme isomers that form be formed from palmitic and linolenie acids. Which of the PS isomers aft not likely ll> be found in biological membranes?
Expert Solution & Answer
Interpretation Introduction
Interpretation:
The PS isomer which is not likely to be found in biological membranes should be determined.
Concept Introduction:
There are two wide kinds of isomers: stereoisomers and constitutional.
Constitutional isomers vary in connectivity and bonding, whereas stereoisomers vary in 3-D orientation.
Answer to Problem 1P
Two structures having linolenic acid is connected to the initial carbon and palmitic acid is attached to the second carbon.
Explanation of Solution
Lipid is in proximity within biological membranes. Formation of double bond results in the bend in the chain which creates space among lipids.
Phosphatidyl serine molecules contain the big group on glycerol’s third carbon. Due to this group, the 2nd and 3rd carbons of glycerol contain more space as compared to the first carbon.
The fatty acid that attaches to the first carbon is usually a saturated fatty acid. An unsaturated fatty acid attaches to the second carbon.
Phosphatidylserines contain the phosphate bond in the serine residue on the 3rd carbon of glycerol.
Linoleic acid contains two common forms, thus, there are four kinds of different phosphatidylserines created with linoleic and palmitic acid.
The structure is shown as follows:

You were tasked with purifying an untagged transcription factor (molecular weight 65,000Da, isoelectric point unknown) from a contaminant Protein A (molecular weight 50,000 Da, isoelectric point 5.0). You were also instructed to use the protein for crystallization studies after purification.i) In the initial purification step, which type of chromatography should you attempt? Explain your choice and specify the requirements of the buffer solution you should use. ii) Analyzing the proteins recovered from step i) using SDS-PAGE, you still observed a faint band of Protein A in addition to the transcription factor band. Given the limited time available for further purification, you must choose ONE appropriate chromatography method to maximize the chances of separating the two proteins as well as your crystallization studies. Provide a detailed explanation of your selection and the techniques/strategies you would employ to achieve this.

- Patients with pyruvate dehydrogenase deficiency show high levels of lactic acid in the blood. However, in some cases, treatment with dichloroacetate (DCA), which inhibits the kinase associated with the pyruvate dehydrogenase complex, lowers lactic acid levels. How does DCA act to stimulate pyruvate dehydrogenase activity? DCA activates pyruvate dehydrogenase kinase. DCA increases phosphorylation levels of pyruvate dehydrogenase. DCA inhibits pyruvate dehydrogenase kinase. ODCA activates pyruvate dehydrogenase phosphatase. What does this suggest about pyruvate dehydrogenase activity in patients who respond to DCA? The pyruvate dehydrogenase complex is active only when phosphorylated by the kinase. The pyruvate dehydrogenase complex is active only in the presence of the kinase. The pyruvate dehydrogenase complex is completely inactive. The pyruvate dehydrogenase complex displays some residual activity.arrow_forwardThe reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron-transport chain.

[glucose] = What does the calculated substrate concentration at 90% Vmax tell you if normal blood glucose levels range between approximately 3.6 and 6.1 mM? Hexokinase operates near Vmax only when glucose levels are low. Hexokinase normally operates far below Vmax. Hexokinase operates near Vmax only when glucose levels are high.

AG +29 kJ mol¹ (+7 kcal mol-¹) Malate + NAD+ oxaloacetate + NADH + H+ The reaction proceeds readily under physiological conditions. = Why does the reaction proceed readily as written under physiological conditions? The NADH produced during glycolysis drives the reaction in the direction of malate oxidation. The steady-state concentrations of the products are low compared with those of the substrates. The reaction is pushed forward by the energetically favorable oxidation of fumarate to malate. Endergonic reactions such as this occur spontaneously without the input of free energy. Assuming an [NAD+ ]/[NADH] ratio of 8, a temperature of 25°C, and a pH of 7, what is the lowest [malate]/[oxaloacetate] ratio at which oxaloacetate can be formed from malate? [malate] [oxaloacetate]arrow_forwardCalculate and compare the AG values for the oxidation of succinate by NAD+ and FAD.

The electron-transport chain can regenerate FAD, but not NAD+. FAD is an oxidant, whereas NAD+ is a reductant. The oxidation of succinate requires two NAD+ molecules but only one FAD molecule. The oxidation of succinate by NAD+ is not thermodynamically feasible. kJ mol-1 kJ mol-1arrow_forward
- Use the cellular respiration interactive to help you complete the passage. 2,4-dinitrophenol (DNP) was a popular ingredient in diet pills in the 1930s before it was discovered that moderate doses of the compound cause exceptionally high body temperature and even death. Complete the passage detailing how DNP's mechanism of action explains why it causes both high body temperature and weight loss. 2,4-dinitrophenol (DNP) causes of returning to the mitochondrial matrix through to pass directly across the inner mitochondrial membrane instead proteins.

The runner's nutritionist suggests replenishing carbohydrate stores by eating carbohydrates. However, the runner is also concerned about weight loss and wants to know if fats can be directly converted into carbohydrates. How should the nutritionist respond to the runner? Yes, the glyoxylate cycle can be used to convert acetyl CoA into succinate, which can then be converted into carbohydrates. No, the two decarboxylation reactions of the citric acid cycle preclude the net conversion of acetyl CoA into carbohydrates. No, the citric acid cycle converts acetyl CoA into oxaloacetate, but there is no pathway to form glucose from oxaloacetate. Yes, pyruvate carboxylase can convert acetyl CoA into pyruvate, which can be used to form glucose through gluconeogenesis.arrow_forward
