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.
Proteins. Proteins are made of C, H, O, N and S. The building units of proteins are amino acids. Each amino acid contains an amino group, a carboxyl group, a central carbon and hydrogen, and an R group. Variation on R group defines different amino acids. There are 20 different amino acids.
