Cells create proteins by linking amino acids together into a chain called aPolypeptide. Each link is created by a dehydration reaction between the amino group of one amino acid and the carboxyl group of the next amino acid in the chain. Proteins are composed of one of more polypeptide chains. Your body can make an enormous variety of proteins by arranging different amino acids in different orders
What else can I help you with?
What cellular structure assembles amino acids into polypeptides?
Ribosomes are the cellular structures responsible for assembling amino acids into polypeptides during the process of protein synthesis. Ribosomes are composed of rRNA and proteins and can be found in the cytoplasm or on the endoplasmic reticulum.
What is formed when amino acids formed long chains or polymerize?
Polypeptide chain, precursor to protein. The chain of amino acid itself is not enough to be a functional protein, so it must go through additional changes before it can be functional. The chain may be cut into pieces (proteolysis), have carbohydrates attached to it (glycosylation) or have phosphate groups attached to it (phosphorylation).
What is a chain of more than 50 amino acids?
A chain of more than 50 amino acids is called a protein. Chains of amino acids in general can be called polypeptides - which refers to the type of bond between the amino acids (a peptide bond).
What determines the different shapes and functions of proteins?
A protein's structure is determined by:- the amino acid sequences of its polypeptide chains;- hydrogen bonds between amino acids in polypeptides;- other bonds (e.g. hydrophobic interactions, disulphide bridges) between side chains in the polypeptides; and- the arrangement of polypeptides (in a protein that contains more than one polypeptide)Scientists have mapped the structures of several proteins; however, scientists are still unsure as to how proteins actually form their final structures.The function of a protein is directly related to its structure. For example, a protein that fights a certain bacteria might have a shape that allows it to bind to the bacteria and then destroy it.
What are the polymers of protein?
Proteins are polymers made up of amino acids linked together by peptide bonds. They are long chains of amino acids that fold into specific three-dimensional structures to carry out various functions in the body.
What molecule is formed from polypeptides?
protein
What are chains of amino acids known as?
They are known as protein chains or polypeptides
The pancreatic enzyme that reduces the large protein molecule polypeptides is?
trypsin
What determines the functional structure of a protein?

For example, a protein that fights a certain bacteria might have a shape that allows it to bind to the bacteria and then destroy it.
What part of the cell are polypeptides made in?
Polypeptides are made in the ribosomes of the cell. Ribosomes are responsible for protein synthesis by translating the information from messenger RNA (mRNA) into amino acid sequences, which eventually form polypeptides.
What is a protein made up of three separate polypeptides called?
A protein made up of three separate polypeptides is called a trimer. Trimeric proteins consist of three individual protein subunits that come together to form a functional complex. Each of the three polypeptides in a trimeric protein may contribute unique structural and functional properties to the overall structure.
Polymer of a protien?
Normally you can just refer to the polymers just as proteins, but if you want to be specific, you can say polypeptide, thereby excluding amino acids, dipeptides, and oligopeptides. The monomers of proteins are amino acids.
What uses the amino acid sequences of polypeptides to predict a protein's three-dimensional structure?
Bioinformatics
Which enzyme helps in the digestion of protein?
trypsin and pepsinPepsin in the stomach converts protein into polypeptides ( grouos of amino acids )
Macromolecule made of one or more polypeptides?
A protein is a macromolecule made up of one or more polypeptides. Polypeptides are chains of amino acids linked by peptide bonds, and when one or more polypeptide chains fold into specific 3D structures, they form functional proteins that carry out essential biological functions in living organisms.
What is closely related to proteins?
Many things are closely related to proteins, including polypeptides and amino acids.
How are amino acids polypeptides and peptide bonds related?
Amino acid polypeptides are made up of a chain of amino acids held together by peptide bonds.
