Triplet states generally have much longer lives (take longer to de‐excite) than singlet states and are at a lower energy level.

1. Glucogenic amino acids- which are degraded to pyruvate, α-ketoglutarate, succinyl-CoA, fumarate, or oxaloacetate and are therefore glucose precursors

2. Ketogenic amino acids- which are broken down to acetyl-CoA or acetoacetate and can thus be converted to fatty acids or ketone bodies

Cysteine, tryptophan, and methionine are not common amino acids: together, they constitute approximately 5 percent of the amino acids in a typical protein. Four amino acids—leucine, serine, lysine, and glutamic acid—are the most abundant amino acids, constituting 32 percent of all the residues in a typical protein.
