Rennet is a complex of enzymes that digest milk, the primary enzyme being chymosin or rennin.
Lactase
lactase
Lactase is the enzyme that breaks down lactose.
Lactase. (the suffix- ase means an enzyme)
the enzyme is not the right shape for sucrose
lactase
Lactose is digested in the small intestine by an enzyme called lactase. Lactase breaks down lactose into glucose and galactose, which can then be absorbed into the bloodstream. These simple sugars are then used by the body for energy.
Lactase is the enzyme that breaks down lactose.
The enzyme lactose.Lactose.
The enzyme which the body uses to digest lactose is lactase.
A substrate is the substance in which an enzyme act, or a process occurs. For example lactose is a substrate, but water is not.
Lactose intolerance is the inability to efficiently convert lactose into glucose and galactose, a reaction catalyzed by the enzyme lactase. (A rule of thumb for enzyme nomenclature is that many enzyme names typically take most of the name of their substrate and slap an "-ase" at the end.)
Enzymes are highly specific in their action. For example, enzyme maltase acts on sugar maltose and not on lactose or sucrose. Different enzymes may act on the same substrate but give rise to different products. For example, raffinose gives rise to melibiose and fructose in the presnce of enzyme sucrase while in the presence of enzyme melibiase it produces lactose and sucrose. Similarly an enzyme may act on different substrates like sucrase can act on both sucrose and raffinose producing different end products.
Lactase
as a general rule, anything ending in -ase is an enzyme, so lactase is an enzyme that breaks down molecules of lactose
Milk naturally contains the sugar lactose. Lactose-free milk is made by 'pre-digesting' the lactose in the milk. This is done by adding the enzyme lactase to the milk. The enzyme breaks down the lactose and people who can't digest lactose properly (lactose intolerance) can drink the milk without side-effects.
lacZ codes for the enzyme beta-galactosidase, which splits lactose into glucose plus galactose. lacY codes for a "permease" protein that allows lactose to enter the cell, and lacA codes for an enzyme that acetylates lactose.
