Who is the man responsible for the first modern system of classification

In the 18th century, Carl Linnaeus published a system for classifying living things, which has been developed into the modern classification system.

Six amino acids have side chains that are polar but not charged. these are serine (ser), threonine (thr), cysteine (cys), asparagine (asn), glutamine (gln), and tyrosine (tyr). these amino acids are usually found at the surface of proteins, as discussed in the proteins 2 module.
