Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.
Range
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
Enzymes in the digestive system and hydrolases are both types of proteins that catalyze chemical reactions to break down molecules. Specifically, hydrolases are a subset of enzymes that catalyze hydrolysis reactions, breaking down molecules by adding water.
Pectinases are hydrolases because they break down the pectin molecule by catalyzing the hydrolysis reaction, where water is used to break the bonds within pectin. Oxido-reductases are enzymes involved in oxidation-reduction reactions, and transferases are enzymes that transfer functional groups between molecules, neither of which describe the function of pectinases.
An abhydrolase is any of a family of hydrolases with an alpha/beta hydrolase fold.
An amidohydrolase is any of a class of hydrolases which act upon amide bonds.
Lysosomes do conatain acid hydrolases that help digest or break down the contents of nonfunctional organelles. This is not necessarily 'dangerous' to the cell, because it only degrades tissue that is not useful.
because the lysosomes are loaded with acid hydrolases
An amidase is another name for an amidohydrolase, any of a class of hydrolases which act upon amide bonds.
The main types of enzymes are oxidoreductases, transferases, hydrolases, lyases, isomerases, and ligases. These enzymes catalyze different types of chemical reactions within cells to help facilitate various metabolic processes.
Phospholipid hydrolases do.
Hydrolases - Hydrolysis of a substrate - digestive enzyme isomerases - change of the molecular form of the substrate - famerase
Lysosomal hydrolases are enzymes that are synthesized in the endoplasmic reticulum and then modified in the Golgi apparatus before being targeted to the lysosomes. Once in the lysosomes, these hydrolases help break down various macromolecules into smaller components for cellular recycling.
