Default pattern

This pattern is based on the WHO 2002 technical report on protein and amino acid requirements in human nutrition, page 245. It corresponds to amino acid requirements for adults, given in g per kg of body mass. Absolute quantities shown below correspond to daily requirements for a 62 kg adult. Methionine+cysteine requirements were translated into separate methionine and cysteine requirements with relative proportions of 70%/30%. Similarly for phenylalanine+tyrosine requirements.
