The molecules of life

All living things are built from four basic types of "building blocks": sugars, fatty acids, amino acids (which form proteins), and nucleotides (which form DNA and RNA). These molecules are organised in various structures in the cell, including the cell membrane, nucleus, and organelles.

Sugars (a), protein (b), DNA (c) and fats in lipid double layer (d)
