FIGURE 4.

Plasma phenylalanine concentration (A) and L-[ring-²H₅]-phenylalanine enrichment (B) over time during the postabsorptive and 4-h postprandial period following the ingestion of 25 g protein from mycoprotein (MYCO; n = 12), spirulina (SPIR; n = 12) or chlorella (CHLO; n = 12) and execution of a bout of unilateral-resistance leg exercise in healthy young adults. Time 0 represents the time of protein ingestion. Values are mean ± SD. Data were analyzed with two-way repeated-measures ANOVA (time × group), with Bonferroni post hoc tests used to detect differences at individual intervals. Time × group interaction; both P < 0.001. a, significant difference for MYCO compared with SPIR (P < 0.05); b, significant difference for MYCO compared with CHLO (P < 0.05); c, significant difference for SPIR compared with CHLO (P < 0.05). CHLO, chlorella; MPE, mole percent excess; MYCO, mycoprotein; SPIR, spirulina.
