Concept explainers
Interpretation:
To draw the open chain structure of sorbitol and this molecule is five or six membered cyclic acetal it should be identified.
Concept Introduction:
Carbohydrates: These molecules are large class of naturally occurring polyhydroxy
Monosaccharide: It is simple sugar the carbohydrate contain three to seven carbon atoms in respective place.
Aldose: A monosaccharide that contains a one aldehyde group in
Ketose: A monosaccharide that contains a one keto carbonyl group in
Acetal: An acetal is one of organic molecule where two separate oxygen atoms are single bonded to a central carbon atom it is called acetal. In other words compound that has two ether groups

- Name the following fatty acids by the symbol (C:B)arrow_forwardIn the monosaccharide derivatives known as sugar alcohols, the carbonyl oxygen is reduced to a hydroxyl group. For example, D-glyceraldehyde can be reduced to glycerol. However, this sugar alcohol is no longer designated D or L. Why?arrow_forwardThe 6-member pyranose ring of glucose is formed through the interaction of the hydroxyl group on C5 with the aldehyde group What kind of ring is formed when the hydroxyl group on C4 attacks instead? Draw the Haworth projection of the products with all the carbons labelled accordingly and name them Why would ring formation through C6 or C3 be unfavorable?arrow_forward
- Vitamin C is ascorbic acid. If you examine the structure of asorbic acid given in the background secton (equation 2) there is no -COOH group present. In the structure shown, the ascorbic acid is as a lactone or cyclic ester. Write the equation for the hydrolysis (cleaveg by addition of water) of the lactone to the carboxylic acid.arrow_forwardThe conversion of 1,3-bisphosphoglycerate (1,3-BPG) to glyceraldehyde 3-phosphate (GAP) represents a reduction. an oxidation. no change in oxidation state. d reaction isarrow_forwardThe melting points of a series of 18-carbon fatty acids are: stearic acid, 69.6 °C; oleic acid, 13.4 °C; linoleic acid, −5 °C; and linolenic acid, −11 °C.(a) What structural aspect of these 18-carbon fatty acids can be correlated with the melting point?(b) Draw all the possible triacylglycerols that can be constructed from glycerol, palmitic acid, and oleic acid. Rank them in order of increasing melting point.(c) Branched-chain fatty acids are found in some bacterial membrane lipids. Would their presence increase or decrease the fluidity of the membrane (that is, give the lipids a lower or higher melting point)? Why?arrow_forward
- Isomerization of the following ketose can give two aldoses. Draw the structures of the two aldoses and provide their names. CH2OH CH2OH OH ? онarrow_forwardMyristoleic acid is a monounsaturated fatty acid found in small amounts in a variety of foods. Calculate the net ATP yield from the complete β-oxidation of myristoleic acid. The formula of myristoleic acid is shown below (it is assumed that the total ATP production is the same for both saturated and unsaturated fatty acids having the same carbon chain length). CH3-(CH2)3-CHCH-(CH2)7-COOH (Given: The oxidation of one NADH yields 2.5 ATP; the oxidation of one FADH2 yields 1.5 ATP; and the oxidation of one acetyl CoA yields 10 ATP. ) Group of answer choices a. 96 ATP b. 92 ATP c. 94 ATP d. 34 ATP e. 36 ATParrow_forwardName which, if any, of the following groups are notaldose–ketose pairs: d-ribose and d-ribulose, d-glucose and dfructose, d-glyceraldehyde and dihydroxyacetone.arrow_forward
- Tridecane [CH3(CH2)11CH3] is a major component of the repellent that the stink bug Piezodonis guildinii releases from its scent glands when attacked. What fatty acid gives tridecane on decarboxylation?arrow_forwardWhich of the following is a true statement regarding sphingolipid synthesis? (A) The first step in sphingolipid synthesis is the condensation of palmitoyl CoA with aspartate to form b-ketosphinganine.(B) This process requires the reduction of a ketone that uses NADH as the reducing agent.(C) A fatty acid is attached to dihydrosphingosine to form dihydroceramide. (D) FAD is using as an oxidizing agent to remove a double bond from dihydroceramide.(E) The formation of sphingomyelin requires the attachment of a glucose or galactose molecule to ceramide.arrow_forwardThe diversity of functional groups on sugars that can form glycosidic bonds greatly increases the information content of glycans relative to oligopeptides. Consider three amino acids, A, B, and C. How many tripeptides can be formed from one molecule of each amino acid? Now consider three sugars- glucose, glucuronic acid, and N-acetylglucosamine. Use shorthand (eg., Glca(1 → 4)GICUAB(1 → 4)GICNAC) to represent 10 trisaccharides with the sequence Glc-GlcUA-GluNAc. Is your list exhaustive?arrow_forward
