AnswerProteins are composed of amino acid molecules linked together by peptide bonds. They are globular regions that result from the combination of motifs that fold independently from the rest of the polypeptide chain to give a stable structure.

Proteins are complex macromolecules polymers.

. Proteins are very large molecules composed of basic units called amino acids. Proteins are of great nutritional value and are directly involved in the chemical processes essential for life. Proteins are biomolecules composed of amino acids that participate in nearly all cellular activities.

Protein molecules are large complex molecules formed by one or more twisted and folded strands of amino acids. Think of amino acids as train cars that make up an entire train called a protein. The typical protein is constructed from a single set of amino acids.

Correct answer to the question Describe the general composition of a protein molecule. Peptide bond is produced when carboxyl radical of one amino acid reacts with the amino -NH 2 group of the other amino acid. Folding in proteins happens spontaneously.

C H N S and O are typical atoms that compose amino acids. Figure 3-3 The 20 amino acids found in proteins. Proteins structures are made by condensation of amino acids forming peptide bonds.

A protein consists of a polypeptide backbone with attached side chains. Describe the general composition of a protein molecule 2 Describe how the. When amino acids are joined by dehydration synthesis a process that removes water to form a chemical bond they form peptide bonds.

There are three main components of an amino acid the amino group the. Describe the general composition of a protein molecule. Protein highly complex substance that is present in all living organisms.

The importance of proteins was recognized by chemists in the early 19th century including Swedish chemist Jöns Jacob Berzelius who in 1838 coined the term protein a word derived from the. Therefore it is the sequence of the chemically different side chains more Panel 3-1 The 20 Amino Acids Found in Proteins. In addition to containing carbon hydrogen and oxygen amino acids contain nitrogen.

The general structure of α-amino acids is shown in. The amino acid composition of proteins. The secondary structure is determined by the dihedral angles of the peptide bonds the tertiary structure by the folding of proteins chains in space.

A protein contains at least one long polypeptide. Proteins are large molecules consisting of many amino-acids connected by peptide linkages. Proteins are biological polymers composed of amino acids.

Proteins are formed by amino acids which are produced based on the genetic information in a cell. Proteins are organic compounds which are polymers of amino acids. Each amino acid consists of a central carbon.

Describe the general composition of a protein molecule 2 Describe how the from BIO MISC at Community College of Aurora. Describe the general composition of a protein. Occurring in the cytoplasm translation is the process through which proteins are synthesized.

The primary structure of a protein is the specific number and order of amino acids that make up the protein chain called a polypeptide a simple protein molecule. There are 20 different amino acids which make up proteins. There are 20 amino acids commonly found in organisms.

The basic structural formula of amino acids is shown in Fig. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. Short polypeptides containing less than 2030 residues are rarely considered to be proteins and are commonly called peptides or sometimes oligopeptides.

All proteins are made up of amino acids. They are organic compounds made up of hydrogen oxygen carbon and nitrogen atoms. Proteins have complex shapes that include various folds loops and curves.

Amino acids are the proteins building units. Each type of protein differs in its sequence and number of amino acids. The sequence of amino acids in a protein is called its primary structure.

One or more polypeptide chains twisted into a 3-D shape form a protein. Olenka 21 1 year ago. Proteins contribute to the biochemical processes that preserve life.

They consist of 40-400 amino acids except motor and kinase domains that are formed by a much larger number of amino acids. The α-carbon atom also carries a carboxyl group COOH. The common property of all proteins is that they consist of long chains of α-amino alpha amino acids.

They have high molecular weight and are made up of structural units monomers called amino acids. Nucleic acid and protein structure. The α-amino acids are so called because the α-carbon atom in the molecule carries an amino group NH 2.

A protein is a folded polymer structure which contains a polypeptide chain polymer which contains amino acids monomers. Every protein is specially equipped for its function. A protein is a polymer of amino acids.

The individual amino acids are. A polypeptide chain is chain composed of amino acids. School Community College of Aurora.

Amino acids linked together by peptide bonds form a polypeptide chain. The central carbon is bonded to an amine group N H 2 a carboxyl group COOH a hydrogen atom and an R group. Learn vocabulary terms and more with flashcards games and other study tools.

Then the amino acids that are created in the cell are linked together in a certain order.
