    In plants, it has important roles in nucleic acid metabolism, carbohydrate and protein metabolism, cell wall synthesis, cell wall structure, membrane integrity and function, and phenol metabolism. [20] Probably essential to animals, for reasons not well understood. [21] Toxic to both animals and plants. [22] bromine: 35: 5

    The secondary-structure elements are connected by "loop" or "coil" regions of non-repetitive conformation, which are sometimes quite mobile or disordered but usually adopt a well-defined, stable arrangement. [16] The overall, compact, 3D structure of a protein is termed its tertiary structure or its "fold".

    Structure of a typical prokaryotic cell. Prokaryotes include bacteria and archaea, two of the three domains of life. Prokaryotic cells were the first form of life on Earth, characterized by having vital biological processes including cell signaling. They are simpler and smaller than eukaryotic cells, and lack a nucleus, and other membrane-bound ...

    Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...

    Some proteins have structural or mechanical functions, such as actin and myosin in muscle, and the cytoskeleton's scaffolding proteins that maintain cell shape. Other proteins are important in cell signaling, immune responses, cell adhesion, and the cell cycle.

  8. Cellular component - Wikipedia

    en.wikipedia.org/wiki/Cellular_component

    A ribosome is a biological machine that utilizes protein dynamics on nanoscales to translate RNA into proteins. Cellular components are the complex biomolecules and structures of which cells, and thus living organisms, are composed. Cells are the structural and functional units of life. [1]
