Biological Secretion: How Your Cells Regulate Mood and Mind
Definition and Fundamental Principles of Secretion The term secretion refers to the highly complex and essential cellular process by which specialized cells synthesize and release specific, biologically active products. This activity is fundamentally distinct from mere excretion, which is the removal of waste products; instead, secretion involves the active elaboration of substances designed for physiological […]
PEPTIDE
Definition and Classification The term peptide refers to a short series of amino acids that are linked together by covalent bonds known as peptide bonds. These molecules constitute the fundamental building blocks of larger structures, specifically proteins, and play indispensable roles as signaling molecules across virtually all biological systems. Peptides are distinguished from proteins primarily […]
