All 20 Amino acids visible in 3-D on a single page

This page displays the 20 proteinogenic amino acids - those normally involved in the synthesis of proteins - but there are many others with minor molecular differences.
Each molecular model is independently movable in any direction by mouse dragging, and extra information may be revealed by hovering your mouse over the name at the bottom.
Various links highlight molecular features in each section. Clicking on the name below will also bring up individual amino acids in a larger individual viewer.

Every amino acid has an amino group ( -NH₂ : blue, with 2 whites) and a carboxylic acid group (-COOH : grey, with 2 reds and a white). Each one also has a unique R group - 6 or 7 categories. *Start .. stop rotation*	glycine - gly	alanine - ala	valine - val	leucine - leu	isoleucine - ile	ALIPHATIC These R groups are simple (linear) groups of carbon and hydrogen atoms
HYDROXY These R groups have an extra -OH group (red and white)	serine - ser	threonine - thr	lysine - lys	histidine - his	arginine - arg	BASIC These R groups contain extra N atoms which contribute basic (alkaline) characteristics
AROMATIC These R groups have rings based on benzene	phenylalanine - phe	tyrosine - tyr	tryptophan - trp	cysteine - cys	methionine - met	SULPHUR- CONTAINING These R groups contain sulphur!
DICARBOXYLIC & AMIDES These R groups contain -COOH or - CONH₂ groups	aspartic acid - asp	asparagine - asn	glutamic acid - glu	glutamine - gln	proline - pro	IMINO The >NH group (blue dot in the ring) makes this an imino acid, not an amino acid (not a property of the R group)
