No, generally proteins have not catalytic properties, typical roles of proteins are
- Components of the body structure (muscles for example);
- Element of information transmission among cells;
- Transportation proteins (like Cholesterol for example that is used tot transport fat molecules in blood)
- Antibodies
and many others
A particular class of proteins however do exist, enzymes, that are the most used catalytic substances in nature.
They are however only a particular category among proteins.

∙ 11y agoYes enzymes are proteins that can lower the energy of the transition state in a reaction which is what a catalyst does. One of the first enzymes to be characterized is called Catalase for it's function as a catalyst in the breakdown of H2O2 into O2 and H2O.

If two proteins contain the same type and number of amino acids but the order in which they link up is different are the properties of the two proteins the same?
no, it changes the properties. ex: phy-lhe is different than lhe-phy sources: exploring creation with biology 2nd edition
What molecule contains all the information a cell needs to make proteins?
The DNA contains the 'blueprints' for proteins.
To manufacture proteins all cells also contain?
Mitochondria
If a cell did not have ribosomes it would be unable to?
synthesize protein, it will not be able to manufactur the proteins which is fundamental for the cells wore work effctively and produce atp energy
Definition is properties detected with your senses?
Physical properties. Colour, shape, state of matter (e.g. solid, liquid, gas), texture, sound, smell, and taste are all physical properties.
Who stated that all not all enzymes are proteins?
Thomas R. Cech and Sydney Altman received the 1989 Nobel Prize in Chemistry "for their discovery of catalytic properties of RNA".
Which is the biology discipline that studies the proteins?
For catalytic proteins, enzymology and for structural biology, structural proteins
What is an abzyme?
An abzyme is an antibody with catalytic properties.
What is abzyme?
An abzyme is an antibody with catalytic properties.
Why is DNA frequently found associated with proteins inside of cells?
Histones are proteins which are associated with DNA and from nucleosomes, which pack the DNA. Transcription factors, proteins involved in DNA synthesis, replication...
How do the properties of proteins make them such useful catalysts?
No
What is a side chain in proteins?
There are no side chains in proteins, but the side chains in amino acids, the building blocks of proteins, determine their unique properties.
What are two other factors that affect the rate of the reaction?
The properties of reactants (reactivity) and catalytic behaviour
Do bio-molecules have common physical and chemical properties?
No. Biomolecules are a diverse group, and do not have common physical and chemical properties. Proteins, carbohydrates, lipids, nucleotides, etc. are all different both physically and chemically.
What form of RNA forms a particle where proteins are assembled?
This catalytic form of RNA is called ribosomal RNA, rRNA.
Do proteins form hormones enzymes and connective tissue?
Enzymes are catalytic proteins. Connective tissue is, well, tissue and is made of cells, but proteins such as collagen do play an important role. Some hormones are proteins and some are not. An example of a protein that serves as a hormone is insulin. However, hormones such as testosterone or thyroxin are NOT proteins.
What is proteins purpose in a cell?
Terrestrial life's central information storage molecule is DNA. The information in DNA is read-out by machinery that is made of proteins (and RNA). The information is also translated into proteins (through RNA). This makes proteins, DNA, and RNA the central informational molecules of life. But of the three classes of molecules, proteins express the most functional complexity. So the short answer is that proteins perform most of the functional processes in a cell.The information in proteins allows them to catalyze the key chemical reactions of life (these reactions are sometimes loosely referred to as metabolism). Most enzymes can make chemical reactions occur, in a regulated fashion, thousands of times faster than they normally occur. Catalytic proteins are called enzymes. Other proteins have seemingly miraculous structural properties. For example, silk is comprised entirely of protein, and is a very strong fiber. Muscle, the eye's lens, and hair are all made of structural proteins.
