2) Proteins are polypeptide chains consisting of monomers called amino acids, which are made up of carbon, hydrogen, oxygen and nitrogen. Amino acids are made up of an amino group, an R group a carboxyl group and an alpha carbon, the different R groups of each individual amino acids determines which amino acid they will form.…
Proteins-Macromolecule containing one or more polypeptide chains. are nitrogenous organic compounds that have one or more amino acid chains. They are structural components of body tissues, enzymes and antibodies…
A). The chemical composition and structure of proteins seems quite confusing at first but one it is broken down into levels it is much more understandable. Amino acids are the basic building blocks of proteins and they contain amino, carboxyl and R groups. These R groups that are in the amino acids are what determine the properties of the specific amino acids. For structure, there are 4 levels. The first one being the primary level. These are made up of sequences of amino acids and these amino acids are linked together by peptide bonds. The next level is called secondary. This level is a formation of amino acid chains folded together by a helix formation or a pleated sheet. The bonds between…
General protein structure and chemical bonds: Contains hydrogen, oxygen, carbon, and nitrogen. Comprised of amino acids, a nitrogen (amino) group, a carboxyl (acid) group, a hydrogen, and a side chain (R) which determines protein function and name…
Protein is essential in repairing and making new cells and also supplying the energy needed for an organism to grow…
Proteins are a part of every cell, tissue, and organ in our bodies. The protein we eat is broken down by amino acids that are later used to replace proteins in our bodies. These proteins include meats, poultry, fish, eggs, nuts, seeds, milk and milk products.…
Proteins build cells, cause change in other cells, make enzyme to control functions, and help move material through the plasma membrane.…
Polypeptides are amino acids linked together by peptide bonds therefore creating a structure known as a polypeptide. A polypeptide backbone is a key contributor to the secondary structure of a protein due to the backbone to backbone hydrogen bonding interactions.…
Proteins: a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, collagen, etc., and as enzymes and antibodies.…
Proteins are complex molecules that each has a very unique shape, structure and function. The shape of the proteins is held up by a chain of subunits called amino acids that are connected by peptide bonds. Protein structures are formed by four levels of folding. The primary structure is the linear sequence of amino acids. The secondary structure describes the folding of alpha helixes and beta pleated sheets. The tertiary structure represents the overall shape of the protein and the quaternary structure only occurs in a protein consisting of more than one amino acid chain. When the shape, the structure or the function of proteins is incorrect, it is likely because of some type of change in the sequence of the amino acids or whether a certain amino acid required is present.…
Proteins are made up of groups of twenty different amino acids. In the average adult, twelve of those acids are made in the body, and the other eight we have to ingest through our food. Those eight are called the essential amino acids. Amino acids cannot be stored in the body, so we need to eat foods regularly that contain the essential amino acids. We get most of our high quality proteins from meat and dairy products (Trefil & Hazen, 2013).…
All the four macromolecules=lipids, proteins, carbohydrates and nucleic acids= are essential for the functioning of an organism 's body (Campbell, biology). They work hand in hand to help us survive. For example, Lipids are an immediate energy source. ATP, for example, is used by the body when in energy deficit. Proteins are needed to form muscles and bones. Carbohydrates are the main energy source for the body. Without this energy, we would not be able to…
How do new molecules form to support growth? For a molecule to form, two or more atoms need to join together chemically. Proteins are made of smaller molecules called amino acids. Amino acids contain the elements carbon, oxygen, hydrogen, nitrogen, and sometimes sulfur. Amino acids are used by your cells to build proteins needed for proper cell functioning.…
A Macromolecule is a molecule with a very large number of atoms .The word macromolecule is usually used for describing polymers. Molecules that are made up of smaller molecules are called monomers, there are also Organic Molecules composed of carbon atoms .The functions of the Four big Macromolecules: First, Carbohydrates, carbohydrates is the function of being used for energy production during cellular respiration. Second , Lipids, lipids are used for four things; insulation and long-term energy storage, being a primary component of cell membranes, hormonal functioning, and help control the fluidity of cell membranes, Also lipids or fats are composed of fatty acids . Third, Nucleic Acid, the functions of nucleic acid is storing genetic material, transferring genetic information called DNA and RNA to ribosomes for protein synthesis, that carries Amino acids into place and Polypeptide keeps the chain of amino acids together ,also DNA is composed of nucleotides ,and holds ribosomal subunits together, Deoxyribose replaces hydroxyl in groups . Four, Protein, The functions of proteins are structural support in things such as hair and nails, protection against germs, and bodily movements. Carbohydrates are…
Why should we care about proteins? • Proteins perform structural and functional roles in the body • Your body uses them, to build and repair tissue. It is an important building block of bones, muscles, cartilage, skin, and blood. • Proteins are a major key in making hormones like insulin • Albumin, which is a protein made by the liver acts like the bloods 24-hour service that attaches to and transports fatty acids, calcium, and other substances through the circulatory system to cells throughout the body • Immunoproteins are blood proteins that act like the bodies disease defense system The Essential and Non-Essential Amino Acids • The building blocks of proteins are amino acids • 20 common amino acids (9 are considered essential and 11 are…
