Amino Acid Signaling Molecules

Meaning

Amino acid signaling molecules are a distinct class of chemical messengers derived from protein building blocks that regulate cellular communication and function within the body. These molecules, such as neurotransmitters and certain peptide hormones, transmit vital information between cells, tissues, and organs. Their role extends beyond simple protein synthesis, influencing complex processes like mood, metabolism, and endocrine secretion. Maintaining an adequate supply is essential for robust physiological signaling pathways.
