Noun
any of a group of enzymes (trade name Lactaid) that hydrolyze lactose to glucose and galactose
Source: WordNetAmong mammals, lactase persistence is unique to humans — it evolved relatively recently (in the last 10,000 years) among some populations, and the majority of people worldwide remain lactase nonpersistent. Source: Internet
Lactose is inhibiting the repressor, allowing the RNA polymerase to bind with the promoter, and express the genes, which synthesize lactase. Source: Internet
Eventually, the lactase will digest all of the lactose, until there is none to bind to the repressor. Source: Internet
Humans are born with high levels of lactase expression. Source: Internet
In humans, it requires a special enzyme ( lactase ) for disassembly during digestion. Source: Internet
It is broken down when consumed into its constituent parts by the enzyme lactase during digestion. Source: Internet
