(a)
To determine: The structural aspect of the 18-carbon fatty acids can be correlated to the melting point
Introduction:
Fatty acids are a class of lipids. They are non-polar compound this means they can only dissolve in non-polar solvents such as benzene, diethyl ether, and hexane. Fatty acids can be saturated or unsaturated. Saturated fatty acids are those which do no possess any double bond in its structure, For example: Palmitic acid and stearic acid. While unsaturated fatty acids possess one or more double bonds, For example: Oleic acid and linoleic acid.
(b)
To draw: The possible triacyglycerols that can be constructed from glycerol, palmitic acid, and oleic acid, and also rank them in order of increasing melting point.

To determine: The presence or absence of branched-chain fatty acid increase or decrease the fluidity of the membrane.

- Sodium fluoroacetate (FCH 2CO2Na) is a very toxic molecule that is used as rodentpoison. It is converted enzymatically to fluoroacetyl-CoA and is utilized by citratesynthase to generate (2R,3S)-fluorocitrate. The release of this product is a potentinhibitor of the next enzyme in the TCA cycle. Show the mechanism for theproduction of fluorocitrate and explain how this molecule acts as a competitiveinhibitor. Predict the effect on the concentrations of TCA intermediates.arrow_forwardIndicate for the reactions below which type of enzyme and cofactor(s) (if any) wouldbe required to catalyze each reaction shown. 1) Fru-6-P + Ery-4-P <--> GAP + Sed-7-P2) Fru-6-P + Pi <--> Fru-1,6-BP + H2O3) GTP + ADP <--> GDP + ATP4) Sed-7-P + GAP <--> Rib-5-P + Xyl-5-P5) Oxaloacetate + GTP ---> PEP + GDP + CO 26) DHAP + Ery-4-P <--> Sed-1,7-BP + H 2O7) Pyruvate + ATP + HCO3- ---> Oxaloacetate + ADP + Piarrow_forwardTPP is also utilized in transketolase reactions in the PPP.
