Over 90% of a cell's dry weight is composed of proteins, which are vital for virtually every cellular function. The topic of protein synthesis, therefore, is a fundamental pillar of biology, but its complexity is taught at different levels depending on the educational curriculum, spanning both foundation and higher-tier studies.

Over one-third of the energy used by the human body at rest comes from lipids. The properties of lipids in A-Level biology are diverse and essential for understanding how living organisms function, from energy storage to the structural integrity of cell membranes.

Approximately 90% of the body's energy reserves are stored as lipids within adipose tissue, highlighting their crucial role in long-term energy management. The remarkable efficiency of lipids as an energy store is a fundamental concept in A-level biology, rooted in their unique biochemical properties.
