If you look at the biomolecules and see which of them are present inside human bodies, you will be shocked to know that there are not more than four significant types of biomolecules and all the other biomolecules fall under these four categories. The four biomolecules are well explained in the class 11 biology chapter 9 ncert solutions, for your perusal.
Proteins - These are said to be the prime building material present in the human body. From your hair to your skin, muscles to macro and micro organs, all are made from proteins. In addition to this, proteins have the property, which makes your bone strong and yet flexible. However, It has a complex 3-D structure. Proteins are formed when there is a bond between amino acids. The amino acids are from the amine group compound on one end and the other end's carboxyl group compound,so it becomes acidic.
Fats - These fats are also known as lipids, and they help living organisms store energy for long. Fat molecules are relatively compact, and they are lightweight too, so,as a result, they work as a sponge to absorb and store excess amounts of energy.
Carbohydrates - Glucose is another word for carbohydrates. A common form of carbohydrates is sugar which gives you a quick energy source as it is easily broken down. The more complex carbohydrates consist of the glucose subunits, which are strung together by di-saccharides, tri-saccharides, and poly-saccharides.
Nucleic Acid - These nucleic acids are the ones that contain genetic codes and have all the information that is required to build a body. The nucleotide is the basic unit of nucleic acid which is composed of sugar and phosphate structures.
The characteristics that make living organisms different from non-living organisms are growth, breathing, reproduction, digestion, ability to sense, etc. Despite having non-living parts present inside the body, how can a living organism perform all the tasks that make them fall under the category of a living being? With the help of Biomolecules class 11 ncert solutions, you will get to know how the living body works. Also, what biomolecules help a living body perform its daily tasks.
