Protein chemistry is a huge area which covers things such as:
– protein structure (primary, secondary and tertiary)
– amino acid modification
– how differing amino acid combinations result in alter catalytic capabilities.
– protein modification by attachment of prosthetic groups
and even these 4 general topics can be broken down into further subgroups.
So is there is anything in particular yo are looking to know about then write a comment and I will get back to you.
