The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).
What is the monomer for a protein?
For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein (Figure 1).
Which of these is not a lipid?
Hence, the correct answer is ‘Polysaccharide‘.
Which molecule is not a carbohydrate?
Which molecule is not a carbohydrate? lipid (A lipid is a hydrophobic polymer, not a carbohydrate.)
What is a central carbon atom?
A carbon atom bonded to only one other carbon atom is a primary carbon atom, which is designated by the symbol 1°. The carbon atom at each end of a carbon chain is primary. For example, butane has two primary carbon atoms.
Which functional groups are polar and nonpolar?
Common functional groups in biology
Is a glucose molecule a monomer?
Sugar Monomers: Glucose is the most common natural monomer. It links together to form polymers of Starch, Cellulose and Glycogen. Glucose also provides a vital source of energy for many organisms.
What is the monomer of glucose?
Monosaccharides contain carbon, hydrogen, and oxygen molecules. These monomers can form long chains that make up polymers known as carbohydrates, the energy-storing molecules found in food. Glucose is a monomer with the formula C6H12O6, meaning it has six carbons, twelve hydrogens and six oxygens in its base form.
What is proteins monomers and polymers?
Proteins – polymers are known as polypeptides
monomers are amino acids. Nucleic Acids – polymers are DNA and RNA
monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group.
Is glucose a lipid?
Answer and Explanation: The molecule “glucose” is characterized as a simple sugar which indicates that it is a type of carbohydrate.
Which of these is a lipid?
Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Lipids are not soluble in water as they are non-polar, but are thus soluble in non-polar solvents such as chloroform.
What are lipids Mcq?
Lipids are energy-rich organic, non-polar molecules. These organic compounds contain carbon, hydrogen and oxygen atoms that form a framework for the structure and function of living cells. They are insoluble in water and only soluble in nonpolar solvents as water is a polar molecule.
What is the glucose molecule?
Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form. Glucose is naturally occurring and is found in its free state in fruits and other parts of plants.
What molecule is a carbohydrate?
A carbohydrate is a naturally occurring compound, or a derivative of such a compound, with the general chemical formula Cx(H2O)y, made up of molecules of carbon (C), hydrogen (H), and oxygen (O). Carbohydrates are the most widespread organic substances and play a vital role in all life.
Is glucose a carbohydrate?
The two main forms of carbs are: simple carbohydrates (or simple sugars): including fructose, glucose, and lactose, which also are found in nutritious whole fruits.
Which statement correctly describes glucose C6H12O6 )?
Which statement correctly describes glucose (C6H12O6)? It is a compound made of twenty-four total atoms of three different elements.
Which atom is a carbon atom?
Carbon (from Latin: carbo “coal”) is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth’s crust.
Is carbon a molecule or element?
Carbon is a chemical element with symbol C and atomic number 6. Classified as a nonmetal, Carbon is a solid at room temperature.
Which functional groups are hydrophobic?
Classifying Functional Groups
An example of a hydrophobic group is the non-polar methane molecule. Among the hydrophilic functional groups is the carboxyl group found in amino acids, some amino acid side chains, and the fatty acid heads that form triglycerides and phospholipids.
How can you tell if a functional group is polar or non-polar?
Instead, it’s about the types of bonds between atoms. When 2 equally strong (electronegative) atoms are bound, the sharing of electrons will be equal between them. If a functional group is composed of an atom that has strong-weak bonds, the group will be polar.
Which functional groups are hydrophilic?
Hydrophilic functional groups include hydroxyl groups (resulting in alcohols though also found in sugars, etc.), carbonyl groups (giving rise to aldehydes and ketones), carboxyl groups (resulting in carboxylic acids), amino groups (i.e., as found in amino acids), sulfhydryl groups (giving rise to thiols, i.e., as found …
Is C6H12O6 a monomer or polymer?
Is C6H12O6 (glucose) a monomer, or a polymer? Monomer d. To summarize, when two monomers are joined, a molecule of water is always removed.
Is glucose a polymer?
Glucose polymers are simply extended chains of glucose otherwise known as starch and cellulose. In terms of dietary supplements, one of the best aspects of glucose polymers is the fact that they have been scientifically proven to provide certain benefits.
Is glucose a carbohydrate monomer?
1. Glucose is one of several different carbohydrate monomers called monosaccharides. To build the ring version of glucose, start by constructing a closed ring formed by five carbon atoms and one oxygen atom.
What are monomers called?
Monomers basically create blocks for molecules, including proteins, starch and many other polymers. Four big monomers are found: amino acids, nucleotides, monosaccharides, and fatty acids. The main forms of macromolecules are those monomers: proteins, nucleic acids, carbohydrates, and lipids.
What type of organic molecule is glucose the monomer for?
|Elements||C, H, O, N, S||C, H, O|
|Examples||Enzymes, muscle fibers, antibodies||Sugar, glucose, starch, glycogen, cellulose|
|Monomer (small building block molecule)||Amino acids||Monosaccharides (simple sugars)|
Is glucose a polysaccharide?
The major component in the rigid cell walls in plants is cellulose and is a linear polysaccharide polymer with many glucose monosaccharide units.
How are monomers and polymers related to the unity and diversity of life?
Within each class of biomolecules, carbohydrates, lipids, proteins, and nucleic acids, there is unity in the fact that the same monomers are used again and again, and diversity results from putting the monomers together in different ways.
How does the formation of nucleic acid polymers differ from the formation of polysaccharides?
Answer. Nucleic acid polymer genrally form either DNA or RNA by differing the base composition. The basic unit of polysaccaride is the monosaccaride which is connected via glycosidic linkage.
How do molecules become polymers and how are polymers broken down relate this back to dehydration and hydrolysis reactions?
When polymers are broken down into smaller units (monomers), a molecule of water is used for each bond broken by these reactions
such reactions are known as hydrolysis reactions. Dehydration and hydrolysis reactions are similar for all macromolecules, but each monomer and polymer reaction is specific to its class.
