Concept explainers
(a)
Interpretation:
The IUPAC name for the following alkane should be determined.
Concept introduction:
Naming
•Name an alkane by determining the number of carbons in the longest continuous chain.
•Assign a name from the compounds in the alkane series (e.g., butane, pentane, and hexane).
•Add the names of substituents attached to the longest chain, writing the name as a single word.
•Number the carbon at which the substituent is attached. Separate the number from the name by a hyphen. Each substituent must have a number.
•The substituents are usually given in alphabetical order, but assigned the number of the carbon to which the substituent is attached.
•Begin numbering at the end of 1°, the chain closest to the first substituent.
•Because they have some similar properties, it is sometimes convenient to refer to some organic compounds as 1° (primary), 2° (secondary), 3° (tertiary), and 4° (quaternary). A primary alcohol contains an alcohol

•Because they have some similar properties, it is sometimes convenient to refer to some organic compounds as 1° (primary), 2° (secondary), 3° (tertiary), and 4° (quaternary). A primary alcohol contains an alcohol functional group attached to a carbon that is, in turn, attached to no other carbons. A secondary alcohol contains a hydroxyl group attached to a carbon that is, in turn, attached to only two other carbons.

- for each pair of biomolecules, identify the type of reaction (oxidation-reduction, hydrolysis, isomerization, group transfer, or nternal rearrangement) required to convert the first molecule to the second. In each case, indicate the general type of enzyme and cofactor(s) c reactants required, and any other products that would result.

She then carries out the same experiment using ATP labeled with 32P in the central position, [ẞ-³2P]ATP, but the 32P does not appear in P; within such a short time. Which statements explain these results? Yeast cells reincorporate P; released from [ß-³2P]ATP into ATP more quickly than P¡ released from [y-³2P]ATP. Only the terminal (y) phosphorous atom acts as an electrophilic target for nucleophilic attack. The terminal (y) phosphoryl group undergoes a more rapid turnover than the central (B) phosphate group. Yeast cells maintain ATP levels by regulating the synthesis and breakdown of ATP. Correct Answerarrow_forwardCompare the structure of the nucleoside triphosphate CTP with the structure of ATP.
