Why are biomolecules important to organisms

Structural polysaccharide: They provide mechanical stability to cells, organs, and organisms. Examples are chitin and cellulose. Chitin is involved in the construction of a fungal cell wall, while cellulose is an important constituent of diet for ruminants. Storage polysaccharides: They serve as carbohydrate stores that release sugar monomers when required by the body. Examples include starch, glycogen, and inulin.

Starch stores energy for plants. In animals, it is catalyzed by the enzyme amylase found in saliva to fulfill the energy requirement. Glycogen is a polysaccharide food reserve of animals, bacteria, and fungi. Proteins are unbranched polymers of amino acid residues.

There are about 22 amino acids that are involved in the synthesis of proteins according to their location and function. Proteins are categorized into four groups depending on their structural organization:. Proteins are essential components of organisms. It participates in almost every process within cells. It is involved in the processes of DNA replication, cell signaling, catalyzing metabolic reactions, construction of cell and tissue structures, and transportation of molecules from one place to another.

Given below are eight groups of proteins that are categorized based on their functional properties. Nucleic acids are macromolecules present in cells and viruses, and they are involved in the storage and transfer of genetic information. The nucleic acid was first discovered by Friedrich Miesher in the nuclei of leukocytes.

Structurally, nucleic acids are polymers of nucleotides or polynucleotides which are phosphate esters of nucleosides. The nucleotides are comprised of three components:. DNAs are the hereditary material that resides inside the nucleus. DNA has two other forms as well, A and Z forms. The conformation DNA will adopt depends on the hydration level, DNA sequence, chemical modification of the bases, the type, and concentration of a metal ion in the solution.

The double helix structure represents two polynucleotides DNA coiled around a central helix. The two strands are antiparallel and interact by hydrogen bonds between complementary base pairs. In some cases, like at low pH, the triple helix form of DNA also exists. It is the genetic material that stores all the information required to be transferred to the progeny. It specifies the biological development of all living organisms and viruses. It is believed that, around 4 billion years ago, RNA was the first genetic material!

Scientists say it is largely because of its self-replicating ability and enzymatic activity. This hypothetical period is known as the RNA world. But when the protein-forming enzymes came into existence, DNA became the most dominating and stable form of genetic material.

The other advantage DNA has is that its double-stranded structure allows for the correction of mutations as well.

RNA is present in all living cells. It has different roles to play in different organisms. It acts as genetic material in some viruses and has enzymatic activity in other organisms where it is called ribozyme. All three have essential roles in the development and maintenance of life. They are involved in the transfer of genetic information for protein synthesis via the processes of transcription and translation outside the nucleus , and they control gene expression as well.

Structurally, RNA exists in both single-stranded primary structure and double-stranded secondary structure forms. The double-helical structure of RNA is present in the A form. Though, the physical basis for this difference is still a mystery. Lipids are organic compounds that are insoluble or poorly soluble in water but soluble in organic solvents like dissolves like such as ether, benzene, or chloroform.

They are hydrophobic and structurally composed of a chain of hydrocarbons. They are chemically more diverse than other biomolecules, and they are primarily involved in membrane structure and energy storage. Other than these lipid molecules, some plasma lipoproteins also exist that are structurally a lipid-protein complex. These complexes function as lipid transport systems in blood.

Some examples of lipoproteins are chylomicrons, low-density lipoproteins, and high-density lipoproteins. Biomolecules are vital for life as it aids organisms to grow, sustain, and reproduce. They are involved in building organisms from single cells to complex living beings like humans, by interacting with each other. The diversity in their shape and structure provides diversity in their functions.

The study of these biomolecules is known as biochemistry. Biochemistry deals with the study of their structures, functions, interactions, and reactions. Several functions of these biological molecules are still a mystery and current advanced techniques are being used to discover more molecules and understand their role in life-sustaining processes.

A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly s pecialized , although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields.

Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record. A biomolecule is any molecule that is produced by a living organism, including large macromolecules such as proteins, polysaccharides, lipids, and nucleic acids, as well as small molecules such as primary metabolites, secondary metabolites, and natural products.

A more general name for this class of molecules is biogenic substances. The top open access journals are peer reviewed scholarly journals of [Your Journal Name or subject name]. These provide high quality, meticulously reviewed and rapid publication, to cater the insistent need of scientific community. There are the following varieties: Triglycerides are a part of cell membranes, they store energy reserve in fat cells. Phospholipids are a part of the nervous tissue cell membranes.

They transport fats, fatty acids and cholesterol. Sterol is cholesterol contained in the cell membrane, excludes the influence of temperature on their stability. It is needed to produce vitamin D, production of male and female sex hormones, brain needs and immune system. Moreover, dialysis is also used to concentrate protein solution.

Water molecules are removed from the inside of the dialysis bag by using hydrophilic polymer such as polyethylene glycol. There are two types of Carbohydrates, simple and complex. Carbohydrates are commonly called sugars and provide the major source of fuel to power the animal body, especially the nervous system.

This type of carbohydrate contains one or two sugar units bonded together. Certain complex carbohydrates, like chitin and cellulose, have a slightly different chemical bond that cannot be broken down in the human bond.

Although it goes unused, these carbs play a vital role as they become fiber that helps scrape the walls of the digestive tract giving it a helpful cleaning of unwanted waste. Foods with a low glycemic index steadily release glucose; while foods with a high glycemic index cause rapid blood sugar spike. Low glycemic index foods like yogurt, broccoli, and grapefruit are good for weight….

The value of the proteins, fats and carbohydrates for the body It is well established that the human body is composed of The remaining Maintaining the normal life of the body depends on the ratio of essential nutrients, healthy diet requires the presence of proteins, fats and carbohydrates in a ratio of 1: 3: 5. Proteins Proteins are the main building material of our body, beside that they are also part of hormones, enzymes and antibodies. Thus, without their participation processes of growth, reproduction, digestion and immune defense are impossible.

Different microorganisms play a significant role in each stage ofthe processes. Therefore, intervention and follow up in all the stages is essential for enhanced and optimum methane production. Polymers are transformed into soluble monomers through enzymatic hydrolysis.
