The Aminoacids
This page is a placeholder, or under current development; it is here principally to establish the logical framework of the site. The material on this page is correct, but incomplete.
This page contains essential information on the 20 proteinogenic amino acids that every bioinformatician should commit to memory.
Contents
What properties of the 20 proteinogenic amino acids are worthwhile to remember? Obviously, all those that would be inconvenient to look up when we need them. In practice, this means all those properties that allow us to "read" sequences and evaluate pairwise and multiple sequence alignments. These properties include:
- relative size and shape
- relative hydrophobicity
- charge
- key properties of functionally important side chains
- H-bond donor and acceptor functions
- relative abundance
- propensity of amino acids for secondary structure
The contents for this page needs to be reconstructed, please see the Wikipedia page on proteinogenic amino acids in the interim.
