Biomolecules are organic molecules that are essential for life and are found in all living organisms. They include carbohydrates, lipids, nucleic acids, and proteins. These biomolecules play crucial roles in a variety of physiological processes, including energy production, cellular communication, and structural support.

There are many different types of biomolecules, each with its own unique structure and function. Carbohydrates are molecules made up of carbon, hydrogen, and oxygen atoms, and they serve as a primary source of energy for living organisms. They can be classified as monosaccharides, disaccharides, or polysaccharides, depending on the number of sugar units they contain.

Lipids are another type of biomolecule that includes fats, oils, and waxes. They are composed of carbon, hydrogen, and oxygen atoms, but in a different ratio than carbohydrates. Lipids are important for energy storage, insulation, and structural support in cells.

Nucleic acids are biomolecules that store and transmit genetic information. There are two types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA stores genetic information in the form of a code made up of four nucleotide bases (adenine, thymine, cytosine, and guanine), while RNA uses the same four bases but also includes the base uracil.

Proteins are complex biomolecules made up of long chains of amino acids. They perform a wide range of functions in the body, including catalyzing chemical reactions, transporting molecules, and providing structural support. There are 20 different amino acids that can be combined in various ways to create different proteins.

 The most common food which has a high in protein are almond, beans, broccoli, chicken, cottage cheese, eggs, fish, milk, oats, pulses, seafood, soy, quinoa and yoghurt. Due to the presence of chiral or asymmetric carbon atoms and the absence of a plane of symmetry carbohydrates are generally optically active. Explain through the Watson-Crick model, the secondary structure exhibited by the nucleic acids. The ring, thus formed is a five-membered ring and is named as furanose with an analogy to the compound furan. Amylose is a long unbranched chain polymer of D-glucose while amylopectin is a branched-chain polymer of D — glucose. During denaturation, the protein molecule uncoils from an ordered and specific conformation into more random conformations. Thus living state is in a non-equilibrium steady-state to be able to perform work that is attained via energy provided by metabolism.
