When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein. The polypeptide will then fold into a specific conformation depending on the interactions (dashed lines) between its amino acid side chains.

How does amino acid convert to protein?
Dietary proteins are first broken down to individual amino acids by various enzymes and hydrochloric acid present in the gastrointestinal tract. These amino acids are absorbed into the bloodstream to be transported to the liver and onward to the rest of the body.
Where are amino acids turned into proteins?
The next step in making a protein is called translation. This is when the RNA is converted (or "translated") into a sequence of amino acids that makes up the protein. The translation process of making the new protein from the RNA instructions takes place in a complex machine in the cell called the ribosome.
What determines protein structure?
The primary structure of a protein is determined by the gene corresponding to the protein. A specific sequence of nucleotides in DNA is transcribed into mRNA, which is read by the ribosome in a process called translation.
What is a chain of amino acids called protein?
Proteins consist of one or more chains of amino acids called polypeptides. The sequence of the amino acid chain causes the polypeptide to fold into a shape that is biologically active.
How does protein become ATP?
Lipids are broken down into fatty acids, proteins into amino acids, and carbohydrates into glucose. ... Over a hundred ATP molecules are synthesized from the complete oxidation of one molecule of fatty acid, and almost forty ATP molecules result from amino acid and pyruvate oxidation.
How does protein become energy?
Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins. Broken down into glucose, used to supply energy to cells. Extra is stored in the liver.
How is a protein made step by step?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
Is amino acid a protein?
Amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life.
Where does protein synthesis occur?
Ribosomes are the sites in a cell in which protein synthesis takes place.
How does the sequence of amino acids affect the protein?
The sequence of amino acids of a protein determines protein shape, since the chemical properties of each amino acid are forces that give rise to intermolecular interactions to begin to create secondary structures, such as α-helices and β-strands.
How does sequence of amino acids determine protein shape?
The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape. ... Folded proteins are stabilized by thousands of noncovalent bonds between amino acids.
How do the sequence and composition of amino acids in a protein influence how a protein folds up?
the sequence of amino acids (primary structure) determines how a protein folds. the distribution of attracting and repulsive charges on the amino acids determines how a protein is organised and folded ( and therefore also determines its biological function).
What type of amino acid side chain leads to protein aggregation?
Free thiol groups (also known as sulfhydryl groups) in cysteine amino acid side chains can be oxidized to form covalent disulfide bond linkages or initiate thiol–disulfide exchange [7]. The result is protein polymerization and aggregation.
Which of the following is formed by protein?
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
How do you determine protein sequence?
The two major direct methods of protein sequencing are mass spectrometry and Edman degradation using a protein sequenator (sequencer). Mass spectrometry methods are now the most widely used for protein sequencing and identification but Edman degradation remains a valuable tool for characterizing a protein's N-terminus.
