Nukleotidy, also known as nucleotides, are tiny biological molecules, but their importance in the human body is enormous. Every living cell depends on them to function properly. They are the basic units that form DNA and RNA, which store and transfer genetic information. Without nukleotidy, life at the cellular level would not be possible. Beyond genetics, nukleotidy also play a key role in energy production through ATP, the main energy source for cells. From muscle movement and brain activity to immune defence and tissue repair, nukleotidy support almost every vital process.
This article explains nukleotidy in simple terms, covering their structure, types, biological functions, dietary sources, supplements, medical uses, and future potential in health and science.

What Are Nukleotidy?
Nucleotides vs. Nukleotidy — Terminology
The word nukleotidy is simply another form of nucleotides, commonly used in scientific, medical, and nutritional contexts. Both terms describe the same biological compounds. You may see “nucleotides” in English research papers and “nukleotidy” in educational or international health content. The meaning remains the same. These molecules are essential in biology, genetics, nutrition, and medicine because they form the foundation of DNA, RNA, and cellular energy systems.

Basic Components of Nukleotidy
Each nukleotid is made of three basic parts:
-
Phosphate group – helps connect nucleotides together
-
Sugar molecule – ribose in RNA or deoxyribose in DNA
-
Nitrogenous base – adenine (A), thymine (T), cytosine (C), guanine (G), or uracil (U)
These three components combine to form a single nukleotid. When many nucleotides join together, they create DNA or RNA chains.
Structure of Nukleotidy — The Blueprint of Life
Key Elements and Their Role
Nukleotidy are divided into two main base groups:
-
Purines: adenine (A) and guanine (G)
-
Pyrimidines: cytosine (C), thymine (T), and uracil (U)
DNA uses A, T, C, and G, while RNA uses A, U, C, and G. The difference between DNA and RNA comes from both the sugar type and one nitrogen base. These small structural differences control how genetic information is stored and used.
How They Link: DNA/RNA Chain Formation
Nukleotidy connect through phosphodiester bonds, forming long chains.
In DNA, two chains twist together into a double helix structure.
In RNA, there is usually only one single strand.
These chains create the genetic code that controls growth, repair, reproduction, and inheritance. The sequence of nucleotides acts like letters in a biological language.
Types of Nukleotidy and Their Biological Roles
DNA Nucleotides
DNA nucleotides include adenine, thymine, guanine, and cytosine. Their specific order stores genetic instructions. These instructions determine physical traits, body functions, and how cells behave.
RNA Nucleotides
RNA uses adenine, uracil, guanine, and cytosine. RNA converts DNA instructions into action by helping make proteins.
Different types of RNA include:
-
mRNA – carries genetic messages
-
tRNA – delivers amino acids
-
rRNA – builds ribosomes
Energy-Related Nukleotidy
Some nucleotides store and transfer energy:
-
ATP (adenosine triphosphate) – main energy source
-
GTP, CTP, UTP – support cellular reactions
ATP powers muscle movement, brain activity, digestion, and metabolism.
Signaling Nukleotidy
Nukleotidy like cAMP and cGMP act as signaling messengers. They help cells communicate, respond to hormones, and regulate growth, metabolism, and immune reactions.
Functions of Nukleotidy in the Human Body
DNA/RNA Synthesis and Genetic Information
Nukleotidy store genetic information and allow DNA replication and repair. They ensure genetic material is passed correctly from one cell to another and from parents to children.
Cellular Energy Transfer
ATP, a nucleotide, is essential for energy transfer. Every cell uses ATP to perform tasks such as muscle contraction, nerve signaling, and chemical reactions.
Immune System Support
Nukleotidy support immune cell growth and repair. They help the body fight infections and recover faster from illness or injury by supporting tissue regeneration.
Cell Signaling and Growth
They regulate cell division, repair damaged cells, and control programmed cell death (apoptosis), which keeps tissues healthy.
Dietary Sources of Nukleotidy — What to Eat for DNA Health
Animal-Based Sources
Rich sources include:
-
Liver and organ meats

Bioavailability and Digestion
The body absorbs nucleotides from food and can also make them internally. Infants, athletes, elderly individuals, and people recovering from illness may need higher amounts.
Nukleotidy Supplements — Do You Need Them?
When Supplementation Is Considered
Supplements may help:
-
Athletes with high energy demands
-
People with digestive issues
