OEE: Let's move to more examples where lean tools work great; OEE (Overall Equipment Effectiveness) is a great example to demonstrate that, in our industry, there are areas that should leverage OEE as an equipment performance metric, and where OEE does not add value.
Making the world better, one answer at a time. The seven protein classes are structural proteins, storage proteins, defensive proteins, transport proteins, signal proteins, contractile proteins, and enzymes.
There are 20 amino acids that make up proteins. The main chain has an N terminal which is an amino group (NH 2) and a C terminal which is a carboxyl group (COOH). The side chains make each amino acid unique. The 20 different amino acids can be classified into six different classes based on their side chain(R group).
