Proteins are the main building blocks and functional molecules of the cell, taking up almost 20% of a eukaryotic cell's weight, the largest contribution after water (70%). Proteins are made from small molecules called amino acids. There are many types of proteins some of which are: * Structural proteins
which can be thought of as the organism's basic building blocks. An example is collagen, which is the major structural protein of connective tissue and bone.
* Enzymes
which perform (catalyse) a multitude of biochemical reactions, such as altering, joining together or chopping up other molecules. Together these reactions and the pathways they make up is called metabolism. For example the first step in the glycolysis pathway, which is the conversion of glucose to glucose 6-phosphate, is catalysed by the enzyme hexokinase. Usually enzymes are very specific and catalyse only a single type of reaction, however the same enzyme can play a role in more than one pathway.
* Transmembrane proteins
are key in the maintenance of the cellular environment, regulating cell volume, extraction and concentration of small molceules from the extracellular environment and generation of ionic gradients essential for muscle and nerve cell function. An example is the sodium/potassium pump.

What name is given to the building blocks that make up protein as small units that combine together to make up long chains?
Amino acids are the building blocks that make up proteins. These small units combine together in long chains to form proteins, which carry out various functions in the body.
Why is the cell called the basic unit of all living matter?
It is a matter of perspective. Cells are the building blocks for tissue. Tissue is the building block for organs. Organs are the building blocks for the body. Proteins are the building blocks for cells.....molecules are the building blocks for proteins.....atoms are the building blocks for molecules.

What are some nutrients you get from meat?
Protein! Proteins are the building blocks of life. We eat proteins and then digest them all the way down to the amino acids which they were formed from. Then our bodies use them to synthesize the proteins which make us.

Proteins are the building blocks of cells?
pretty much, for the lack of a better answer. Proteins do make up much of the cells, but so do lipids
What does the body use protein for?
The body uses proteins as "building blocks" - proteins are required by the body for everything from cell wall building to muscle control.

Is protein an amino acid?
No, they are the building blocks of protiens, or they make the proteins.
What name is given to the building blocks that make up protein as small units that combine together to make up long chains?
Amino acids are the building blocks that make up proteins. These small units combine together in long chains to form proteins, which carry out various functions in the body.
How do nitrogen and oxygen help make life possible?
Animals need oxygen to breathe, and together with hydrogen, it makes water. Nitrogen is used by plants, and is one of the building blocks for proteins.
What are some examples of monomers in proteins?
Some examples of monomers in proteins include amino acids such as glycine, alanine, and lysine. These monomers are the building blocks that make up the structure of proteins.
