<p>Three amino acids are given below:</p>

<p>Alanine :&nbsp;<span class="equation">\(CH_3CH(COOH)(NH_2)\)</span>.</p>

<p>Aspartic acid : HOOC -&nbsp;<span class="equation">\(CH_2CH(COOH)(NH_2)\)</span>&nbsp;and</p>

<p>Lysine :&nbsp;<span class="equation">\(H_2N-(CH_2)_4-CH(COOH)(NH_2)\)</span></p>

<p>(i) Make two tripeptides using these amino acids and mark the peptide linkage in both cases.</p>

<p>(ii) Represent alanine in the zwitter ionic form</p>
