A biochemist figures out how living things work at the level of molecules: how enzymes speed up reactions, how proteins fold, how drugs bind their targets. You can get hired with a bachelor's degree as a research associate or lab technician, but independent scientist roles usually need a PhD, and many involve postdoctoral training. This roadmap is built in three stages. First you master the core science and basic lab thinking. Then you become employable with real bench skills, data analysis in Python or R, and clear scientific writing. Finally you move toward leading projects, determining macr

Stage 1 of 3 · about 20 weeks
Understand the chemistry and biology of the cell well enough to explain why a reaction or pathway works, and do the math and lab arithmetic that backs it up.
General and organic chemistry
Every biological process is chemistry. If you understand bonds, acids and bases, and functional groups, then amino acids, sugars and lipids stop being things to memorize and become things you can predict.
Core biochemistry: proteins, enzymes, metabolism
This is the heart of the job. You need to know how enzymes work, how kinetics describe them, and how glycolysis, the TCA cycle and oxidative phosphorylation connect, because most experiments probe one of these.
Molecular and cell biology
Biochemists study molecules inside cells. Knowing the central dogma, DNA replication, gene regulation and signaling tells you where your protein or pathway sits and what a result means.
Math and statistics for science
Biochemistry is quantitative: concentrations, rates, logarithms, error bars. Good statistics keep you from fooling yourself with noisy data.
Lab basics and record keeping
Reproducible work depends on accurate pipetting, correct solution prep, safety habits and a notebook someone else can follow.
