# Functional Biochemistry > Functional Biochemistry examines how the body's biochemical processes support or disrupt the actual functions of its tissues and organs — energy production, detoxification, hormone balance and immune response — in a living person, dynamically and as an integrated whole, rather than as static laboratory values. The concept of Functional Biochemistry was founded by Chris Astill-Smith D.O. ## Content - [The Field](https://functional-biochemistry.com/#field): What Functional Biochemistry is, and how it differs from classical biochemistry. - [The four functions](https://functional-biochemistry.com/#functions): Energy production, detoxification, hormone balance and immune response. - [Christopher Astill-Smith](https://functional-biochemistry.com/#founder): Biography and career of the founder of the field. - [Career timeline](https://functional-biochemistry.com/#timeline): Dated record of qualifications, teaching and appointments. - [The Mission](https://functional-biochemistry.com/#mission): The purpose of the discipline. - [Core Philosophy](https://functional-biochemistry.com/#philosophy): The four principles underpinning the field. - [Enquiries](https://functional-biochemistry.com/#enquiries): How to make contact. - [Full text](https://functional-biochemistry.com/llms-full.txt): The complete text of the site as markdown. ## Optional - [Privacy](https://functional-biochemistry.com/privacy): How enquiry information is handled. - [Terms](https://functional-biochemistry.com/terms): Terms of use and the educational nature of the content.
