A detail that
surprised us

“

In 1972, Balaram’s PhD publication in the Journal of the American Chemical Society introduced the negative NOE as a unique tool to probe protein structures, a concept still fundamental in NMR spectroscopy today.

The Story

1
In 1972, Padmanabhan Balaram introduced the concept of the negative Nuclear Overhauser Effect (NOE) as a novel probe to study macromolecular structures while completing his PhD at Carnegie Mellon University.
2
🌟 During his postdoctoral research at Harvard in 1972-73, he contributed to the total synthesis of vitamin B12 and the asymmetric synthesis of erythromycin under Nobel laureate Robert Burns Woodward.
3Returning to India in 1973, Balaram joined the Indian Institute of Science’s newly formed Molecular Biophysics Unit, working closely with G.N. Ramachandran to study peptide conformations.
4His pioneering research on the unusual amino acid alpha-aminoisobutyric acid (Aib) revealed its role in stabilizing 310-helices in peptides, advancing knowledge of peptide secondary structures in the 1980s.
