Concept explainers
(a)
Interpretation:
The structure of the major product is to be predicted when leucine is treated with
Concept introduction:
The chemical compounds in which carbon is bonded with the acidic and basic group along with hydrocarbon side chain are known as amino acids. The amino acids are classified into acidic, basic, polar, non-polar, essential, and non-essential categories.
(b)
Interpretation:
The structure of the major product is to be predicted when alanine is treated with methanol in the presence of

(a) Tryptophan is an aromatic amino acid. (b) Lysine is positively charged at pH 7. (c) Asparagine has two amide bonds. (d) Isoleucine and leucine are enantiomers. (e) Valine is probably more water-soluble than arginine.arrow_forwardThe amino acid (S)-alanine has the physical characteristics listed under the structure. Label each of the following as optically active or inactive: a solution of pure (S)- alanine; an equal mixture of (R)- and (S)-alanine; a solution that contains 75% (S)- and 25% (R)-alanine.arrow_forward
- Phenylalanine as N-termminus is incorrect. Please provide the correct solution.arrow_forwardA triglyceride can be optically active if it contains two or more different fatty acids.(a) Draw the structure of an optically active triglyceride containing one equivalent of myristic acid and two equivalentsof oleic acidarrow_forward(a) The isoelectric point (pI) of phenylalanine is pH 5.5.
