Chapter 24, Problem 6P
Interpretation Introduction
Interpretation:
A balanced stoichiometric reaction for the synthesis of phosphatidylethanolamine from glycerol, fatty acyl-CoA and ethanolamine should be written and estimation for
Concept Introduction:
phosphatidylethanolamine synthesis is a combination of two pathways. Phosphatidylethanolamine synthesis starts with phosphorylation of ethanolamine followed by transfer of cytidylyl group from CTP to form CDP-ethanolamine and pyrophosphate. Hydrolysis of this pyrophosphate drives this reaction forward. Then phosphoethanolamine is linked to the diacylglycerol backbone. This diacylglycerol backbone is synthesized by glycerol and fatty acids.

- Glucose and fructose are reducing sugars. Sucrose, or table sugar, is a disaccharide consisting of both fructose and glucose. Is sucrose a reducing sugar? Why or why not? No, because only one anomeric carbon is involved in the glycosidic linkage. No, because both anomeric carbons are involved in the glycosidic linkage. Yes, because the fructose unit can convert to the open-chain form. Yes, because the glucose unit can convert to the open-chain form. Which statements about reducing sugars are true? The oxidation of a reducing sugar forms a carboxylic acid sugar. D-Arabinose (an aldose) is a reducing sugar. Reducing sugars contain keto groups instead of aldehyde groups. A disaccharide with its anomeric carbons joined by the glycosidic linkage cannot be a reducing sugar. A reducing sugar will not react with the Cu² + in Fehlings's reagent.arrow_forwardExamine the pairs of molecules and identify the more-reduced molecule in each pair.
