metilációjában

Metilációjában refers to the process of methylation in Hungarian. Methylation is a fundamental biochemical process where a methyl group (CH3) is added to a substrate. This chemical modification plays a crucial role in a vast array of biological functions across all living organisms. In humans and other animals, methylation is particularly important in regulating gene expression, a process known as epigenetics. By attaching a methyl group to DNA or associated proteins, methylation can switch genes on or off without altering the underlying DNA sequence. This control is vital for cellular differentiation, development, and maintaining normal physiological processes.

Beyond gene regulation, methylation is involved in the metabolism of neurotransmitters, the detoxification of harmful substances, and the synthesis of essential molecules like creatine and carnitine. It is also a key step in the methylation cycle, a metabolic pathway that regenerates methionine, an essential amino acid. Aberrations in methylation patterns have been linked to various diseases, including cancer, neurological disorders, and cardiovascular conditions. Understanding methylation processes is therefore critical for both basic biological research and the development of new therapeutic strategies for a range of health issues.
