Hydrolytic enzyme

Biology  Hydrolysis  Hydrostatic skeleton

Hydrolytic enzymes break down protein, carbohydrate, and fat molecules into their simplest units. The hydrolysis of polymers by hydrolytic enzymes results in free monomers.


Hydrolytic enzymes enable the acrosomal process to penetrate the egg's jelly coat.
The tip of the acrosomal process adheres to special receptor proteins on the egg's surface.
These receptors extend through the vitelline layer, just external to the egg's plasma membrane.

Lysosomal hydrolytic enzymes are manufactured in the rough endoplasmic reticulum (Rough ER), from whence they are transferred in a transport vesicle to the cis face of the Golgi apparatus or complex (see Figure 1).

In biochemistry, a hydrolase is an enzyme that catalyzes the hydrolysis of a chemical bond. For example, an enzyme that catalyzed the following reaction is a hydrolase: ...

Those enzymes are called hydrolytic enzymes, and they break down large molecules into small molecules. For example, large proteins into amino acids, or large carbohydrates into simple sugars, or large lipids into single fatty acids.

The sperm cell that reaches the egg cell triggers the acrosome reaction, a process in which hydrolytic enzymes of the acrosome are released on the external surface of the zona pellucida (the protective layer that surrounds the egg cell).

Lysosome: Lysosomes contain hydrolytic enzymes necessary for intracellular digestion. They are common in animal cells, but rare in plant cells. Hydrolytic enzymes of plant cells are more often found in the vacuole.

However, one lysosomal storage disease, I-cell disease ("inclusion-cell disease"), is caused by a failure to "tag" (by phosphorylation) all the hydrolytic enzymes that are supposed to be transported from the Golgi apparatus to the lysosomes.

Lysosomes, shown in Figure 17, are relatively large vesicles formed by the Golgi. They contain hydrolytic enzymes that could destroy the cell. Lysosome contents function in the extracellular breakdown of materials.

lysosome Cytoplasmic, membrane-bounded organelle that contains digestive and hydrolytic enzymes, which are typically most active at the acid pH found in the lumen of lysosomes.

Maltose in lumen of small intestine binds to maltase
Resulting glucose diffuses into the cytoplasm of epithelial cells
Glucoseis also released back into the intestinal lumen and absorbed further down
Thus, duodenum digests food by HYDROLYTIC enzymes (→H2O) ...

Despite this general belief, neither Justus Liebig nor Ernst Hoppe-Seyler, two eminent chemists, accepted this view. Hydrolytic enzymes such as amylase, maltase, and pepsin were known in the nineteenth century, but were not thought to act within cells.
