Some natural populations of humans with lower protein intakes may not experience this inhibition, leading to more endogenous neAA synthesis from carbohydrate and lipid carbon sources, approaching linear mixing. This is suggested by high .C values in some .-consuming populat

Since a shift in . should largely be the result of peptide bond cleaving, no such estimations are possible.
