What molecule that contains the enzyme that makes the pigment of skin and hair?
The molecule that contains the enzyme responsible for producing the pigment in skin and hair is called tyrosinase. This enzyme catalyzes the conversion of the amino acid tyrosine into melanin, the pigment that gives color to skin, hair, and eyes. Variations in the activity of tyrosinase and the type of melanin produced contribute to the diversity of pigmentation among individuals.
What molecule is important because it blocks harmful ultraviolet rays from the sun?
Melanin is the molecule that plays a crucial role in protecting the skin from harmful ultraviolet (UV) rays emitted by the sun. It absorbs and dissipates UV radiation, helping to prevent DNA damage and reducing the risk of skin cancer. Higher melanin levels are associated with darker skin tones, which provide increased protection against UV exposure.
What is the largest molecule to pass through the skin?
The largest molecule known to pass through the skin is typically around 500 daltons in molecular weight. For instance, certain small peptides and macromolecules, like hyaluronic acid, can penetrate the skin barrier, although their absorption is limited. Transdermal drug delivery systems are often designed to optimize the permeation of larger molecules by using enhancers or specific formulations. However, most large molecules do not effectively penetrate the stratum corneum, the outermost layer of skin.
If UV light is required for Vitamin D production does this make UV a Vitamin D precursor?
No UV light can not be treated as vit D precursor as it only provides the energy in the form of radiation for the reaction to take place. It is the steroid molecule present in dermis which is precursor for vitD synthesis.
Is PH3 an element or molecule?
This is a compound, a molecule.
Is skin a cell or molecule?
Skin is composed of trillions of Cells
What begins when a precursor molecule is exposed to ultraviolet light in the skin?
Vitamin D production begins when a precursor molecule is exposed to ultraviolet light in the skin.
Which molecule is responsible for waterproofing of the skin?
The molecule responsible for waterproofing the skin is ceramide. Ceramides are lipids naturally found in the skin that help to form a protective barrier, preventing water loss and keeping the skin hydrated.
How can your body heat water in a swimming pool?
If the temperature of the water is less than your body temperature, then heat will be transferred from the warmer body to the colder body of water. The molecules in your skin vibrate because they are warm. When a water molecule touches a warm vibrating skin molecule, some of the heat energy in the skin molecule is transferred to the water molecule, warming the water.
What type of molecule makes up the skin of arthropods?
polysaccharides
Where in the body in Vitamin D produced and what molecule is it modified from?
Vitamin D is produced in the skin, on exposure to UV (ultravoilet) radiation, from a modified cholesterol molecule; necessary for normal bone growth and function.
Why does sun bathing give you skin cancer?
the ultraiolet rays in a sunbed damages a important molecule (DNA)

Why do some water cling stay to your skin after you take a bath?
Water is a polar molecule so it clings to other water molecules and hangs on your skin even after you dry off a bit.
Why pain occurs when you rub chilli on your skin?
The active molecule in chilies, capsaicin, binds to nerve receptors in the skin, causing a sensation to be sent to the brain exactly like that of a burn or abrasion.
