the.com/katal

the unit that measures how fast enzymes turn chaos into useful work

means The SI unit of catalytic activity, equal to one mole of substrate converted per second, used to quantify how fast an enzyme or catalyst does its job.

from Coined in the 20th century from the Greek 'katalysis' (a dissolving or loosening), the same root behind 'catalyst,' with the '-al' ending shaped to sit alongside other SI units. It was formally adopted into the International System of Units in 1999, giving enzyme kineticists a tidy, official way to say 'speed of transformation.'

defined as
one mole of substrate converted per second
named
from Greek katalysis, meaning dissolution
official since
adopted by the SI in 1999
enormous size
one katal is a staggering amount of activity
real units
enzymes work in nanokatals or microkatals
for instance

urease enzyme activity — commonly measured in katals; breaks down urea at ~4.5 katals per gram in laboratory conditions
