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.
Amino Acids. Proteins are polymers of amino acids joined together by peptide bonds. There are 20 different amino acids that make up essentially all proteins on earth. Each of these amino acids has a fundamental design composed of a central carbon (also called the alpha carbon) bonded to: 1  a hydrogen. 2  a carboxyl group. 3  an amino group. 4  a unique side chain or R-group.
