Which of the following is class of biological molecules?

Last Updated: 21st February, 2020

There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass.

Similarly, what are the 4 classes of biological molecules?

There are four major classes of Biomolecules – Carbohydrates, Proteins, Nucleic acids and Lipids.

Likewise, what type of biological molecule is glycogen? Glycogen is the storage form of glucose in humans and other vertebrates, and is made up of monomers of glucose. Glycogen is the animal equivalent of starch and is a highly branched molecule usually stored in liver and muscle cells.

Correspondingly, what are the types of biological molecules?

The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.

Which of the following classes of biological molecules include enzymes?

Types of biological macromolecules

Biological macromolecule Building blocks Examples
Lipids Fatty acids and glycerol Fats, phospholipids, waxes, oils, grease, steroids
Proteins Amino acids Keratin (found in hair and nails), hormones, enzymes, antibodies
Nucleic acids Nucleotides DNA, RNA

Is water a biomolecule?

A biomolecule is a chemical compound that naturally occurs in living organisms. As clear from above, the essential constituent of bio-molecules are carbon and hydrogen, and water does not contain carbon ,hence, it can not be considered as a bio-molecule.

How are biomolecules formed?

When monomers are linked together to synthesize a biological polymer, they undergo a process called dehydration synthesis. Amino acids are natural monomers that polymerize at ribosomes to form proteins. Nucleotides, monomers found in the cell nucleus, polymerize to form nucleic acids – DNA and RNA.

What are proteins made of?

Proteins are made up of smaller building blocks called amino acids, joined together in chains. There are 20 different amino acids. Some proteins are just a few amino acids long, while others are made up of several thousands. These chains of amino acids fold up in complex ways, giving each protein a unique 3D shape.

How is a protein?

Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein. These proteins bind and carry atoms and small molecules within cells and throughout the body.

How can you tell a biological molecule is a lipid?

How can you tell a biological molecule is a lipid? Lipids are insoluble in water and have a high proportion of nonpolar carbon-hydrogen bonds. They are composed of glycerol and fatty acids. In a saturated fat, all of the carbons are bonded to two or more hydrogens.

Is water a macromolecule?

Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. In the process, a water molecule is formed.

What are biomolecules proteins?

Amino Acids. Proteins are the most diverse biomolecules on Earth, performing many functions required for life. Protein enzymes are biological catalysts, maintaining life by regulating where and when cellular reactions occur. Structural proteins provide internal and external support to protect and maintain cell shape.

What are lipids made of?

Fats, oils, waxes, and sterols are collectively known as lipids. Like the carbohydrates, the true fats contain only carbon, hydrogen, and oxygen. The molecules of such a lipid are made up of a glycerol molecule with three fatty acid molecules attached to it. This kind of lipid is also called a triglyceride.

Where is maltose found in living organisms?

During digestion, starch is partially transformed into maltose by the pancreatic or salivary enzymes called amylases; maltase secreted by the intestine then converts maltose into glucose. The glucose so produced is either utilized by the body or stored in the liver as glycogen (animal starch).
