Summary of Expertise:

Listed with other top experts in: 

His doctoral thesis pertained to the study of fatty acid synthesising enzymes in the different subcellular fractions of rabbit during the development of atherosclerosis and the effect of estrogens on them. The postdoctoral work at Rice University was on the isolation and characterization of the enzyme, dopa decarboxylase from the rat brain by using different new analytical techniques. Further he studied the substrate specificity of this enzyme. The latter study would help in the development of drugs for Parkinson's disease, a disease in which this enzyme plays a role.

More work of his work done on enzymes is described elsewhere in this biography.



He has worked on the following areas as a principal investigator with a group of scientists on the following areas of animal/human nutrition. --optimizing nutrient compositions with commercial advantage in feeds for animals( ruminants/layers/broilers). --Enhancement of immunity thru' mannon oligosaccharides(cell wall components) in birds. --Feed enzymes to improve the quality of feeds (cellulases, phytases etc) --use of stable forms of vitamin C for prawn nutrition --Made presentations / recommendations on how India can be useful as a source of animal nutrition research with cost advantage --Developed for the first time, a highly sensitive qualitative immunoassay for the detection of ricin (castor toxin)by using antibodies from rabbit serum

food research and development

Besides what has been mentioned above, he worked also on the following areas: --Selenium needs for optimum animal performance. --Initiated work on the production of selenomethionine/selenocysteine by growing yeast in a selenium containing medium (work could not be taken further as he retired from service) --As already mentioned, principal investigator of a patented compound for the enhancement of iron bioabsorption in vegetarians by exploiting the structural similarity between chlorophyll and heme. He was also part of the team on conducting the human volunteer trials with the compound. --successfully worked on increasing levels of omega3/omega 6 fatty acids in egg yolk by manipulating the feeds. --Interacted with NGOs in improving the nutritional status of the masses. --He may be useful in assessing the efficacy of the approaches adopted by international bodies in improving the nutritional status in developing countries.


His research/academic background allowed him to undertake work on the exploitation of commercial phytase as a nutrient. He had studied the enzyme for the first time and this later, led to the extensive use of this India in feeds by various commercial feed manufacturers. In particular, he studied its use with phytate rich cereals/brans to -endogenously liberate phosphate -liberate inositol with several benefits -enhance mineral absorption

nutritional biochemistry

As the Head of Animal Nutrition Research, he worked with a team of efficient scientists, on Protected Proteins for the ruminants, wherein good quality dietary proteins are protected from ruminal degradation through heat or formaldehyde. This approach significantly enhanced the milk yield. This work was successfully commercialised by the establishment of systems in the factories for production/quality control, optimization of levels of incorporation in feeds and assessing the efficacy by the milk yield improvement
