Biomolecules play key roles in the structural and functional aspects of tissues. For example, proteins such as collagen and elastin provide structural support in connective tissues, while enzymes catalyze biochemical reactions necessary for cell function. Lipids are essential components of cell membranes, influencing cell signaling and membrane fluidity. Carbohydrates serve as energy sources and participate in cell recognition and adhesion. Nucleic acids, such as DNA and RNA, carry genetic information and are involved in protein synthesis.
