Ribbons are typically used for proteins with an alpha/beta fold, like that of brush border enzymes. A ribbon diagram is an attempt to represent the 3-dimensional structure of the protein in the plane of the screen. The alpha chains are represented as ribbons, with their beta chains represented as arcs that appear above or below the respective alpha chains. Arc widths represent beta strand dangles (bulges) while arc colors represent helix directionality.
A Protein Biosynthesized Internally by The Cell.
A protein is a biological polymer composed of amino acids, which are organic compounds that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur (these six elements constitute about 96% of the human body). When arranged in a chain and linked together by peptide bonds and side chains, these compounds form a long-chain polymer known as a protein.
These proteins play essential roles in all living organisms, from simple single-celled bacteria to complex multicellular organisms such as humans. Proteins can be divided into two main categories: structural proteins , which are involved in the construction of the organism’s cells and tissues; and functional proteins , which perform vital functions for the organism’s survival. Examples of functional proteins include enzymes, hormones, antibodies, receptors and transport proteins.
Each type of protein is made up of one or more polypeptide chains . While these chains contain many different amino acids that determine each protein’s unique chemical nature and structure, they also contain some common components. All polypeptide chains have an N-terminus (or amino terminus) that contains an amino group (-NH2), and a C-terminus (or carboxy terminus).
A Protein That Is Broken Down and Used for Energy.
A protein that is broken down and used for energy. A protein is a substance that is made up of amino acids, which are the building blocks of proteins. There are two types of proteins: structural proteins and enzymes. Structural proteins are found in the muscles, tendons, bones, and skin. They include collagen, elastin and keratin.
Enzymes are proteins that help speed up chemical reactions in the body. Examples include lactase (found in milk), amylase (found in saliva) and pepsin (found in the stomach). Proteins can also be used to create hormones such as insulin or adrenaline which are needed for many vital functions within our body.
A Protein Made by A Specific Gene, The Function of Which Is Determined by The Sequence Of Amino Acids, Or Protein Building Blocks.
The correct answer is B. A protein made by a specific gene, the function of which is determined by the sequence of amino acids, or protein building blocks.A ribosome is composed of two subunits: a large and a small subunit. The large subunit consists of three RNA molecules (rRNA) and over 50 different proteins; the small subunit contains one rRNA molecule and over 30 different proteins.
The ribosomal RNA molecules act as catalysts in peptide bond formation; they are essential to protein synthesis.The ribosome can be broken down into a number of functional domains. The main domain is the peptidyl transferase domain, which facilitates the formation of peptide bonds between amino acids (the building blocks of proteins). This domain is located at the interface between the two ribosomal subunits.
A Protein Involved in Chemical Reactions Within the Cell.
A protein is a molecule that plays a vital role in living organisms by facilitating the chemical reactions within a cell. It is a macromolecule, which is made up of one or several long chains of amino acids. There are 10 different types of classifications for proteins and they are often referred to as the building blocks of life because they are essential to the structure, function, and regulation of cells and tissues.
Proteins can be found in all living organisms, including plants and animals. They are made up of smaller molecules called amino acids that are connected together in specific sequences that form what is known as a long chain.
Amino acids have both acidic and basic functional groups on either side of their carbon atom and this allows them to interact with each other to form bonds. A protein’s structure can be described by how its amino acids are arranged along this chain. The sequence in which these amino acids are arranged determines what type of protein it will become

The zinc metallo-beta-lactamase enzyme is one of hundreds of enzymes that zinc metallo-beta-lactamase protein can perform. The zinc complexed structure of the protein is shown in ribbon format with a ball and stick to describe the elements within the molecule. This diagram also shows an alternating color scheme which helps to realize the 3D nature of the molecule’s complex folding patterns. The zinc metal is seen coupled directly to a serine residue via coordination bonds between carbon, nitrogen, and oxygen atoms within the protein backbone.
