HaN C COO CH2OH L-Serine COO HaN CH2OH D-SerineExplanation / Answer
Proteins are nothing but the polymer of amino acid in which amino acid is linked to each other by peptide bonds i.e. CO - NH linkage. Hence most perfect answer of your question 1st is peptide bonds i.e. option d
Second question answer is e because D and L serine are enantiomers as well as hydrophilic in nature.
They rotate plane polarised light in different location hence called as optical isomer.
