Web4 de mai. de 2024 · Chemical bonding between portions of the polypeptide chain aid in holding the protein together and giving it its shape. There are two general classes of protein molecules: globular proteins and fibrous proteins. Globular proteins are generally compact, soluble, and spherical in shape. Fibrous proteins are typically elongated and insoluble. WebCovalent bonding. A covalent bond forms when two non-metal atoms share a pair of electrons. The electrons involved are in the outer shells of the atoms. An atom that shares one or more of its ...

WebOnce the way atoms are put together is understood, the question of how they interact with each other can be addressed—in particular, how they form bonds to create molecules and macroscopic materials. There are three basic ways that the outer electrons of atoms can form bonds: The first way gives rise to what is called an ionic bond. Consider as an … Web17 de mar. de 2024 · Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O. How are the atoms of a water molecule held together? The atoms in a water molecule are held together by polar covalent bonds. Web20 de jul. de 1998 · Molecules are held together by shared electron pairs, or covalent bonds.
