Enzyme defect: A disorder resulting from a deficiency (or functional abnormality) of an enzyme. For example, newborns are routinely screened for certain enzyme defects, such as phenylketonuria (PKU) and galactosemia.nzyme defect: A disorder resulting from a deficiency (or functional abnormality) of an enzyme.

It takes Saturn 29.45 years (or 10,759 days) to orbit the Sun. Astronomers call the length of time an object takes to go around the Sun its orbital period. So the orbital period of Saturn is 29.45 years. Saturn. Image credit: Hubble. One of the interesting facts about Saturn is that its axis is tilted off the plane of the ecliptic (just like Earth).
Titan orbits Saturn once every 15 days and 22 hours. Like the Moon and many of the satellites of the gas giants, its rotational period is identical to its orbital period; Titan is thus tidally locked in synchronous rotation with Saturn, and permanently shows one face to the planet.
