Concept introduction:
The Cahn-Ingold-Prelog rule system ranks the substituents in the chirality center in the order of decreasing
If the sequence of decreasing priority traces a clockwise path, then the configuration is R, and if it traces a counterclockwise path, the configuration is S.
Triacylglycerols can be produced by reactions of glycerols with acyl coenzyme A molecules.
Two acyl coenzyme A molecules add two acyl groups to the

- Write the equation of reactions of Glucose+Cu(OH)2(heat) Glucose+HNO3 a-D-glucopyranose+(CH3CO)2O a-D-glucopyronase+CH3Iarrow_forwardIn step 7 of fatty-acid biosynthesis (Figure 29-5), dehydration of a -hydroxy thioester occurs to give trans-crotonyl ACP. Is the dehydration a syn elimination or an anti elimination?arrow_forwardIn glycerol metabolism, the oxidation of sn-glycerol 3-phosphate to give dihydroxyacetone phosphate is catalyzed by sn-glycerol-3-phosphate dehydrogenase, with NAD+ as cofactor. The reaction is stereospecific, occurring exclusively on the Re face of the nicotinamide ring.arrow_forward
- Write the haworth projection for (A) B_D_glucofuranose (B) a_D_frotopyranosearrow_forwardAlthough only l-amino acids occur in proteins, d-amino acids are often a part of the metabolism of lower organisms. The antibiotic actinomycin D, for example, contains a unit of d-valine, and the antibiotic bacitracin A contains units of d-asparagine and d-glutamic acid. Draw Fischer projections and three-dimensional representations for these three d-amino acids.arrow_forwardGive one specific sample structure (Fischer Projection or Haworth) of the following carbohydrate derivatives: - Uronic acid - Aldaric acidarrow_forward
- Please draw the haworth projection for D-galactaric acid and D-Galacturonic acid.arrow_forward17. .Draw the dash-wedge structure for the beta-furanose anomer of the L-ketohexose shown below.arrow_forwardThe asymmetric center of glycerol-3-phosphate has the R configuration. Draw the structure of (R)-glycerol- 3-phosphate.arrow_forward
