- Proteins are formed by joining the-CO 2 H end of one amino acid with the-NH 2 end of another to form an amide. The-CONH-bond between amino acids is known as a peptide bond because relatively short polymers of amino acids are known as peptides.

Macromolecule The simple summary is that DNA makes RNA, and then RNA makes proteins. DNA, RNA and proteins all consist of a repeating structure of related building blocks (nucleotides in the case of DNA and RNA, amino acids in the case of proteins). In general, they are all unbranched polymers, and so can be represented in the form of a string.

Proteins 1 Proteins are composed of amino acid subunits that form polypeptide chains. 2  Enzymes catalyze biochemical reactions by speeding up chemical reactions, and can either break down their substrate or build larger molecules from their substrate.  The shape of an enzyme's active site matches the shape of the substrate.

All about protein: What is it and how much do you need? Proteins are organic molecules made up of amino acids – the building blocks of life. These amino acids are joined together by chemical bonds and then folded in different ways to create three-dimensional structures that are important to our body’s functioning. A diagram of protein structures.

- How do cells make proteins? Proteins are large, complex molecules, which all your cells are making continuously. Each protein is made up of many amino acids which must join together in the correct order for the protein to work properly. Imagine a car assembly line: to end up with a working car, the workers must know when and where to add each part. Likewise, the cell needs a set of commands for making proteins. This instruction manual is in your genes - found in the cell nucleus. Enlarge Building a protein is a bit like building a car: to end up with a working car, the workers on the assembly line must know when and where to add each part.

What is Protein Synthesis? Protein synthesis is the process by which individual cells construct proteins. Both deoxyribonucleic acid (DNA) and all types of ribonucleic acid (RNA) are involved in this process. Enzymes in the cell's nucleus begin the process of synthesizing protein by unwinding the needed section of DNA, so that RNA can be made.

What subunits make up carbohydrates? proteins? Large carbohydrates consist of small monomers called monosaccharides. All carbohydrates are composed of carbon, hydrogen, and oxygen in a 1:2:1 ratio. Proteins are composed of monomers called amino acids. Amino acids are composed of nitrogen, carbon, hydrogen, and oxygen. Amino acids bond with each other to form polypeptides. When many polypeptides join, they form proteins. Carbs: 5-ring or 6-ring molecules of carbon atoms with hydrogen atoms off to the side of the carbon atoms.

Protein biosynthesis The amino acids are then linked together to extend the growing protein chain, and the tRNAs, no longer carrying amino acids, are released. This whole complex of processes is carried out by the ribosome, formed of two main chains of RNA, called ribosomal RNA (rRNA), and more than 50 different proteins.

- Protein structure. Protein structure is the three-dimensional arrangement of atoms in a protein molecule. Proteins are polymers — specifically polypeptides — formed from sequences of amino acids, the monomers of the polymer. A single amino acid monomer may also be called a residue indicating a repeating unit of a polymer.

- Proteins (also known as polypeptides) are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are jo … ined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues.

What monomers are proteins made of? What is the structure of the monomer that makes up a protein? Jul 10, 2015. proteins have amino acids as monomers. proteins are made up of 21 different L-amino acids. these amino acids are joined together with peptide bonds. peptide bond is a bond between a caboxylic group of one amino acid with amino group of other amino acid.

What Are Protein Polymers? Amino acids form proteins by linking to each other through connections called peptide bonds. Scientists use the term polymerization to refer to the formation of peptide chains and, as the end result of this process, proteins are technically defined as polymers of amino acids.

Protein Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity.

- Proteins are made of long chains of molecules called amino acids. There are 21 different amino acids, resulting in almost endless possibilities. The sequence, the length, and …the folding structure are all easily varied in proteins. By comparison, carbohydrates and lipids have few variations in structure or make-up.

How many Proteins exist in human body? Proteins are long molecular chains made from one of the 20 basic building blocks of life, Amino acids. The amino acids in a polymer are connected together by the peptide bonds between the carboxyl and amino groups of adjacent amino acids. The carboxyl group contains 1 carbon and 1 hydrogen atom and 2 oxygen atoms (CO-OH). The amine group contains 1 nitrogen atom attached to 2 hydrogen atoms (H-N-H).

What elements make up proteins? Proteins are organic molecules composed of Carbon, Hydrogen, Oxygen and Nitrogen. Proteins are crated by linking together amino acids into protein links called polypeptide chains. There are twenty amino acids of which 12 can be synthesized by the human body and 8 must be ingested in the foods we eat. These 8 are referred to as the essential amino acids. Amino Acids have a basic structure of three components, an amino group made of #-H_2N#, a carboxyl group #-COOH# and the last group is called the R-group or variable group which is composed of Carbon, Hydrogen and Oxygen.
