Breaking Down the Main Functions of Carbohydrates: A Listicle

 Carbon, hydrogen, and oxygen atoms combine to form the macromolecules known as carbohydrates.
It is mostly present in plant foods as lactose and in dairy goods as glucose.

The molecular formula for carbohydrates is (CH2O)n, where n is the number of carbons in the molecule. Put more simply, a carbohydrate molecule is made up of one carbon atom, one oxygen atom, and two hydrogen atoms in a certain ratio. This indicates that the ratio of carbon to hydrogen to oxygen in carbohydrate molecules is 1:2:1. The name "carbohydrate" has its origins in a formula that consists of two components: carbon (carbo) and water (hydrate).

These are chemical compounds with several hydroxyl groups originating from the carbon chain that are arranged as aldehydes or ketones.

Any one of the following three forms can be used to structurally represent carbohydrates:

  • Open chain structure: Carbohydrates have a long, straight chain structure.
  • The glucose's first carbon condenses with the -OH group of the fifth carbon to produce a ring structure under the hemi-acetal structure.
  • The pyranose ring structure, a chemical structure with five carbon atoms and one oxygen atom, is what is known as the Haworth structure.



Below is a discussion of the roles that carbohydrates play in the human body:

  •  Carbohydrates aid in the breakdown of protein molecules, the removal of dehydration, and the removal of ketosis, among other processes.
  • They function as main sources of energy.
  • They supply energy.
  • They support blood glucose control.
  • They give several non-essential amino acids their carbon skeleton through synthesis.
Production of Energy: Carbohydrates are primarily responsible for the body's cells' ability to produce energy. When it comes to energy sources, many cells favor glucose above other substances like fatty acids. Certain cells can only use glucose as their energy source, such as red blood cells.

The first stage of the breakdown of glucose is known as glycolysis, and it involves a complicated set of ten chemical steps. The mitochondria, the cell's power plant, is where the second stage of glucose breakdown takes place. More energy is produced by removing two oxygen atoms and one carbon atom. These carbon bonds release energy, which is transferred to another area of the mitochondria to be used by the cell's energy system in the form that is most useful.




Energy Storage: Extra glucose in the body is stored as glycogen, most of which is kept in the liver and muscles, when the body has enough energy to support its operations. Because glycogen molecules are extremely branched and can hold over 50,000 single glucose units, they can quickly distribute glucose to cells when needed.

Constructing Macromolecules: While the majority of ingested glucose is used to produce energy, some glucose is converted to the essential building components ribose and deoxyribose, which are found in RNA, DNA, and ATP.

In addition, glucose is needed to produce the molecule NADPH, which is involved in several other chemical reactions in the body and is crucial for defense against oxidative stress. Excess glucose can be converted to fat if all of the energy is used to meet the body's demands for construction.

Sparing Protein: Glucose is released from amino acids when the body cannot utilise all of the glucose that is there. Since amino acid molecules cannot be stored, this process necessitates the breakdown of proteins, mostly from muscle tissues. When there is enough glucose available, the body's necessary protein breakdown is essentially prevented from being utilized to produce glucose.

Lipid Metabolism: The body uses lipids less readily as an energy source as blood glucose levels rise. As a result, too much glucose has a "fat-sparing" impact. The reason for this is that elevated blood glucose levels promote the release of the hormone insulin, which instructs cells to use glucose rather than fats for energy synthesis.

The onset of ketosis is also halted by adequate blood glucose levels. A rise in ketone bodies in the blood causes the metabolic disorder known as ketosis. When there is not enough glucose available, as occurs during fasting, cells can turn to the alternate energy source known as ketone bodies.


Simple carbohydrates are made up of one or two sugars with a simple molecular structure (monosaccharides or disaccharides). These are readily converted to energy, which raises blood sugar levels quickly and causes the pancreas to secrete more insulin.

Examples include glucose, galactose, ribose, fructose, lactose, maltose, and sucrose.

Foods: candies, colas, fruit juice, corn syrup, honey, and table sugar

Complex carbohydrates are made up of three or more sugars, either polysaccharides or oligosaccharides, bound together by a more intricate chemical connection. These have a more gradual influence on the rise in blood sugar because they take longer to digest.

Examples include dextrin, rutinulose, amylose, cellulose, and cellobiose.

foods include brown rice, apples, broccoli, lentils, spinach, and unprocessed whole grains.

Use of apomixis in Plant Breeding

 Use of  apomixis in Plant Breeding  The Greek terms "APO" (away from) and "mixed" (the process of mixing or mingling) are the roots of the word "apomixis." It describes how a plant grows from a seed without the need for fertilization or typical sexual reproduction. The easiest way to define apomixis is as a reference to the asexual process. The resultant plant is a female parent plant clone. The female gametophyte, or embryo sac, is created during sexual reproduction by developmental processes that take place inside the ovule. After double fertilization, the resultant components are the embryo and endosperm. In higher plants, apomixis is a common occurrence. More than 35 groups of plants, including the Gramineae, Rosaceae, Compositae, and Rutaceae, are known to be apomictic. Apomixis is seen in major grains like wheat and maize. Apomixis Types There are three commonly known kinds of apomixis: adventitious embryony, apospory, and diplospory. Diplospory T...

Unfoldings of truth behind the conjugation in bacteria

            Unfoldings of truth behind the conjugation in bacteria  The world is home to a vast variety of bacteria. By binary fission, they divide rapidly, creating identical daughter cells. Thus, vertical transmission—the transfer of genetic information from the mother to the offspring—occurs. Bacterial conjugation is a mechanism of transfer of genetic material by which one bacterium transfers genetic material to another through direct contact. Pilus Formation. The donor cells (F+ cells) form a sex pilus and begin contact with an F- recipient cell. Conjugation in Bacteria  DNA is transferred from one bacterium to another during conjugation. DNA is transferred between cells once the donor cell uses a feature known as a pilus to get itself near to the recipient. This DNA typically takes the shape of a plasmid. The fertility factor, also known as the F factor, is a region of DNA found in donor cells that usually causes them to function as donors. T...

Gene Silencing : A brief review

  Gene Silencing : A brief review  Controlling the expression of genes is a phenomenon known as gene silencing. There are two ways to regulate gene expression: translation and transcription. Gene silencing and gene knockdown, in which gene expression is decreased, are quite similar. It must be distinguished from gene knockout, which is the total removal of a gene from the genome. Silencing of Transcriptional Genes Transcriptional gene silencing is the term used to describe the silencing of genes at the transcriptional level. It is a process of alteration in which the machinery of transcription is disabled. The techniques for transcriptional gene silencing are as follows: Mendelian inheritance is the basis for the epigenetic approach known as genomic imprinting. The genes that children acquire from their parents determine how those genes are expressed in them. Histone modification or DNA methylation silences the gene, which is passed down unchanged to the progeny. Paramutatio...
