In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water’s unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies.

Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius.

What is hydrogen bonding in water ? In water, the weak bond formed by the attraction of opposite charges between hydrogen and oxygen from another molecule. What does hydrogen bonding help hold together? Hydrogen bonding help hold together many large molecules, such as proteins weak bond.

Which of the following groups of atoms are most likely to result in hydrogen bonding when paired with hydrogen? Explanation: Nitrogen, oxygen, and fluorine are the three elements most likely to participate in hydrogen bonding.

A hydrogen bond in water occurs between the hydrogen atom of one water molecule and the lone pair of electrons on an oxygen atom of a neighboring water molecule.

Hydrogen bonds are not strong bonds, but they make the water molecules stick together. The bonds cause the water molecules to associate strongly with one another. But these bonds can be broken by simply adding another substance to the water. Hydrogen bonds pull the molecules together to form a dense structure.

Disulfide bonds

Hydrogen Bonds Hydrogen bonds are weak physical side bonds that are also the result of an attraction between opposite electrical charges; they are easily broken by water (wet setting) or heat (thermal styling), and they re-form as the hair dries or cools.

The three types of side bonds are hydrogen, salt, and disulfide bonds.

The keratin and bonds in your hair determine its texture and shape and give each hair around a third of its overall strength. There are three types of bond that link the protein chains together: disulphide bonds (which are strong); and hydrogen bonds and salt bonds (which are weaker).

The disulphide bonds cannot be broken apart by oxidizing agents, which are acids, but can be broken apart by strong reducing agents, which are bases. Alkaline solutions, therefore, are applied to hair to break apart the disulphide bonds. The hair is then held straight and acidic solutions are applied to it.

People with OCA1a have a complete absence of melanin. This is the pigment that gives skin, eyes, and hair their coloring. People with this subtype have white hair, very pale skin, and light eyes.

A deficiency in melanin can lead to several disorders and diseases. For example, a complete absence of melanin causes a condition called albinism. Melanin deficiency has previously been associated with various genetic abnormalities and congenital defects.

Eating vitamin C–rich foods like citrus, berries, and leafy green vegetables may optimize melanin production. Taking a vitamin C supplement may help as well.
