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 are polymers of multiple monomer units called amino acid, which have many different functional groups. More than 500 amino acids exist in nature, but the proteins in all species, from bacteria to humans, consist mainly of only 20 called the essential amino acids.
