PROTEIN & AMINO-ACID FORM COMPARISON
||FUNCTION / VALUE
||Doesn't require digestion; quickly absorbed into
the bloodstream; relatively expensive
||Predigestion speeds entry into digestive system,
but often contains longer chains that must be broken down. Whey and
lactalbumin are examples.
||During exercise, aids in the formation of alanine
from chain glucose, which helps prevent muscle catabolism.
|Di- and Tripeptides
||Two- and three-molecule amino acids that are
||Natural source of protein, often with fiber.
Inexpensive, but incomplete (low in certain essential aminos),
slowly digested and absorbed.
||Natural source containing all essential amino
acids; longer digestion/absorption time, especially with fatty
