Alanine can be transaminated to directly provide pyruvate for gluconeogenesis. This is because alanine transaminase transfers the amino group from alanine to α-ketoglutarate, forming pyruvate and glutamate, which can then enter the gluconeogenic pathway. Glycine, glutamate, ornithine, and aspartic acid do not directly provide pyruvate for gluconeogenesis.
