Interpretation Introduction
Interpretation:
The products of transamination reaction of isoleucine are to be given.
Concept introduction:
In transamination reactions, an exchange of the amino group of the amino acid with a keto group of a α-keto acid takes place to produce a new amino acid and a new α-keto acid.
To give:
The products of transamination reaction of isoleucine.

A transamination can be summarized as an amino group (-NH3") of an amino acid and the keto group (C=0) of an a-keto acid changing places and forming different amino acid
and a-keto acid products, as in the generic reaction below:
amino acid 1 + a keto acid 1
→ aketo acid 2 + amino acid 2

Draw the a-keto acid product of the transamination of an a-keto acid with an amino acid that has the side chain X.

Some nonessential amino acids are synthesized in the body by a simple transamination. The transamination between
oxaloacetate, an a-keto acid, and glutamate, an amino acid with the side chain -CH2CH2COO¯, proceeds according to
the following reaction:
||
→ -00C-CH2 CH2 C-CO0 + amino acid 2
0OC-CH2 CCOO +0OC-CH2 CH2 CH-COO →
NH3+
Predict the structure of the amino acid product, indicated by amino acid 2, for the reaction.
Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template
toolbars. The single bond is active by default. Include all hydrogen atoms and formal charges.

. In bacteria much of the putrescine is synthesized, not from
ornithine but from arginine, which decarboxylates to yield
agmatine. Formulate a plausible pathway from arginine to
putrescine, using this intermediate.
