Amino acid images

Browse our molecular model images of amino acids – from alanine to valine

Amino acids are known as the building blocks of proteins. The majority of amino acids are made up of hydrogen atoms (white), oxygen atoms (red), carbon atoms (black/grey) and nitrogen atoms (blue). Some also have sulfur atoms (yellow). This gallery will help you to understand he structures they share and the R-groups unique to each.
