Amino acids are the small molecule building blocks of peptides and feature, as the name implies, a basic amine functionality and a carboxylic acid functionality disposed about a chiral carbon center. Although many natural amino acids are known, only 22 are so-called proteinogenic, that is they...
The functional group indicated by the arrow is classified as a ___ amine. (A) primary (B) secondary (C) tertiary (D) quaternary One of the two chair structures of cis-1-chloro-3-methylcyclohexane is more stable than the other b...
Describe the differences between secondary structures of DNA and RNA. Given what you know about genetic recombination in bacteria, do you think it is possible for the medical community to stay ahead of antibiotic resistance? Why or why not? Discuss how lipid metabolism is affected with Niemann-Pi...
During the catalytic cycle, amine oxidation to imine reduces a prosthetic flavin moiety, which reacts with O2 to yield H2O2 [126], [127]. Once the flavin is reduced, the rate of O2 binding controls H2O2 generation, with the implication that [O2] influences enzyme activity. The affinity of...
1. Why should care be exercised in handling concentrated acids such as H_2SO_4 and HBr? 2. Why do primary alkyl halides typically undergo S_N2 substitution reactions more rapidly than do secondary or Why does benzoyl chloride react preferentially with an amine rather ...
Saponification is the technical term for the production of soap from fat or lipid. The process involves the reaction between the lipid sample and an aqueous base solution, usually NaOH and KOH, in the presence of heat.Answer and Explanation: ...
Why is bromination more selective than chlorination? Why is benzene less reactive than 1,3,5-cyclohexatriene? Why does benzoyl chloride react preferentially with an amine rather than Na2CO3 or water? Why is it important to use dry tubes for the reactions involving s...
The functional group in a primary amine is the ___ unit. a. -COOH. b. -OH. c. -NH. d. -NH_2. The amino acid lysine has the formula H 2 N ( C H 2 ) 4 C H ( N H 2 ) C O O H . Which functional group is t...
But, since glutamate clearly is associated with many other pathologies, the observations of altered glutamate levels in cancer patients is most likely mechanistically not directly linked to the cancer itself, but rather to secondary biochemical events such as inflammatory responses and thus not ...
a. Secondary b. Tertiary C. More than one response is correct d. Primary. Which of the following amino acids contains sulfur in the side chain? a. Phenylalanine b. Cysteine c. Tyrosine d. Glycine What is the predominant form of each of the following amino acids at pH=11...
