Biophysical chemistry is a physical science that uses the concepts of physics and physical chemistry for the study of biological systems. [1] The most common feature of the research in this subject is to seek an explanation of the various phenomena in biological systems in terms of either the molecules that make up the system or the supra-molecular structure of these systems.

Women selling produce at a market in Lilongwe, Malawi. Food security is the state of having reliable access to a sufficient quantity of affordable, nutritious food.The availability of food for people of any class and state, gender or religion is another element of food security.
While some colleges and universities have dedicated departments of biophysics, usually at the graduate level, many do not have university-level biophysics departments, instead having groups in related departments such as biochemistry, cell biology, chemistry, computer science, engineering, mathematics, medicine, molecular biology, neuroscience ...
Modern biochemistry is considered a sub-discipline of the biological sciences, due to its increased reliance on, and training, in accord with modern molecular biology. Historically, even before the term biochemist was formally recognized, initial studies were performed by those trained in basic chemistry , but also by those trained as physicians .
The scientific approach to food and nutrition arose with attention to agricultural chemistry in the works of J. G. Wallerius, Humphry Davy, and others.For example, Davy published Elements of Agricultural Chemistry, in a Course of Lectures for the Board of Agriculture (1813) in the United Kingdom which would serve as a foundation for the profession worldwide, going into a fifth edition.
Biotechnology has several applications in the realm of food security. Crops like Golden rice are engineered to have higher nutritional content, and there is potential for food products with longer shelf lives. [92] Though not a form of agricultural biotechnology, vaccines can help prevent diseases found in animal agriculture.

Scientific analysis of food and nutrients began during the chemical revolution in the late 18th century. Chemists in the 18th and 19th centuries experimented with different elements and food sources to develop theories of nutrition. [1] Modern nutrition science began in the 1910s as individual micronutrients began to be identified.
