Expert Solution

Molecular Formula- C9H11NO2

(a)

It is also known as F or endorphenyl, it belongs to a class of phenylalanine & derivatives. Phenylalanine & it's derivatives are compounds containing phenylalanine or a derivative there of it resulting from reaction of phenylalanine at the amino group or carboxy group, or from the replacement of any Hydrogen of the glycine by a heteroatom.

Molecular formula- C6H10CIN3O2

(b) It is an alpha amino acid. It consists alpha amino group, a carboxylic acid group and an imidazole side chain, it is classifying as a positively charged amino acid at physiological pH.

(c)Molecular formula- C3H7NO3

D-serine is a selective full agonist with the glycine site of N-methyl-D-aspertate type glutamate receptor.It is a non-essential amino acid and dextro isomer serine with antipsychotic activity.

Molecular formula- C11H12N2O2

(d) It is also known as Trp or W , belongs to the class of organic compounds and it known as Indolyl carboxylic acids. Compounds containing a carboxylic acid chain with atleast 2 carbon atoms & linked to an indole ring.

How many different primary structures could be formed using the four amino acids alanine, phenylalanine, serine and valine? Write the amino acid sequences (using the three letter code) of all the possible peptides that begin with phenylalanine. You must use each amino acid once and only once in each peptide.
