In all instances, however, it is presumed to occur as a result of a reversible transformation of the dissymmetric, optically active substance into an unstable, symmetric one incapable of optical activity; the reverse transformation back from this inactive intermediate is as likely to give one active enantiomorph as the other, so that an inactive mixture results.
Most are previously healthy people who suffered a traumatic brain injury, or oxygen deprivation after a heart attack or stroke, and have been regarded more or less as zombies: patients whose bodies continue to function sometimes for decades but whose minds are incapable of willed activity.

Can you honestly turn your workers into drones incapable of malicious activity, let alone honest mistakes?
Although multinucleated muscle fibers are considered to be permanently differentiated and therefore incapable of mitotic activity, skeletal muscle retains the capacity to repair and regenerate, mainly due to the presence of satellite cells.
Excess H2O2 over-oxidizes the peroxidatic cysteine, rendering Alr4641 incapable of peroxidase activity [ 8].
Numerous metabolic reactions, such as those of the glyoxylate and Entner-Doudoroff pathways, are routinely observed to become dispensable or even incapable of carrying activity under steady genetic and environmental conditions.
Once older patients become incapable of the activities of daily living, such as rising unassisted from a recliner, they are usually institutionalized in nursing homes and assisted living facilities where most remain until death.
These patients are incapable of independent activities of daily living.
