The consequences of unconfined quarks which may have been left over from the big bang, especially as to how they might participate in nucleosynthesis, are examined. Possible properties of the fractionally charged nuclei (Q-nuclei) thus produced, including beta-decay half-lives, binding energies, energy level densities, and thermonuclear reaction rates, are studied. Stellar burning cycles are suggested by these considerations in which the Q-nuclei could contribute significantly to stellar nucleosynthesis, even at an extremely low abundance level, provided that they satisfy some constraints. A model is suggested which accommodates all the constraints thus imposed. Possible implications of the existence of Q-nuclei for stellar evolution are considered, and the results of a calculation are presented which confirm that no obvious conflicts with the known parameters of the sun are encountered. The significance of the possible existence of Q-nuclei for future searches for free fractionally charged entities is discussed. Finally, it is noted that any particle which, when added to a nucleus, increases the nucleon binding energy somewhat could perform stellar burning cycles similar to those described in this paper.
