What kind of amino acids would occur most frequently in the transmembrane domains of integral membrane proteins? What is the molecule that amino acids and proteins all have and carbohydrate and lipid lack? What are molecules composed of long chains of amino acids called?
What are molecules composed of long chains of amino acids called? Which enzyme converts proteins into peptides? What amino acids are hydrophilic? Identify at least three. What kind of bond exists between two amino acids in a protein? A) peptide B) ...
It may consist of atoms of a single chemical element, as with oxygen (O2), or of different elements, as with water (H2O). As components of matter, molecules are common in organic substances (and therefore biochemistry) and are what allow for life-giving elements, like liquid water and bre...

Simply put, molecules are particles composed of two or more atoms that are chemically held together; these molecules have a specific number of atomic nuclei, and can be considered an individual particle. Whether a particle consists of only one type of atom or a variety of different atoms, it...
Genes tell a cell how to function and what traits to express. More specifically, gene regulators turn different genes on and off in different cells, to control cell function. The long molecules of DNA, containing your genes, are organized into pieces called chromosomes. Different species have di...
Diatomic molecules are when only two atoms combine. An example of adiatomic moleculeis carbon monoxide (CO) made of a single atom of carbon and one of oxygen. If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Poly...
Polynitrogen molecules have been studied systematically at high levels of ab initio and density functional theory (DFT). Besides N2, the thermodynamically most stable Nn molecules, located with the help of a newly developed energy increment system, are all based on pentazole units. The geometric,...
They are about the same size, are composed of roughly the same mix of materials, and may have been comparably endowed at their beginning with carbon dioxide and water. However, the twins evolved differently, largely because of differences in their distance from the Sun. With a significant ...
