Scientific profession - sophont who studies biochemistry, or applies that knowledge and techniques in a practical way.
Subfields include microbiology, organic chemistry, elements of physiology and xenobiology, applied (bionano) biochemistry, pharmacology, wetware engineering, psychotropics, neogenics, and biomachinics. Involves study of prebiotic environments and pre-, proto- and cellular biotic metabolism and chemical reactions, the molecular composition of terragen and alien life forms, synthesis and production of crude organobiota; meso- and nano-microscopic analysis and measurement also the effect of various nutrients, drugs, enzymes, hormones, nanites, toxins, and other chemicals on biologicals, the design and synthesis of long chain carbon molecules, and the effect of chemicals and the chemical environment on the growth and metabolism of terragen and xenobiont organisms. Most biochemists have extensive knowledge base and expert system augmentation.
