What molecule makes up 65 90 of the weight of a cell?
Water
: Water is the most abundant chemical compound in living human cells, accounting for 65 percent to 90 percent of each cell.
What percent of phosphorus is in the human body?
Phosphates are essential to life, and this bound form of phosphorus is a major component of essential organic molecules such as phospholipids, ATP, and nucleic acids. It comprises
1.1%
of the total body mass of the human body.
Which element is highest percentage in human body?
For chemistry students and teachers: The tabular chart on the right is arranged by elements in human body. The first chemical element with the highest percentage is
Oxygen
and the last one with the lowest percentage is Magnesium.
Which element is found most in human body?
Oxygen
is the most abundant element in the human body.
The four most abundant elements in the human body –
hydrogen, oxygen, carbon and nitrogen
– account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.
Just four of these –
carbon (C), oxygen (O), hydrogen (H) and nitrogen (N)
– make up about 96% of the human body.
In adult men, about 60%
of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than men, so they have about 55% of their bodies made of water.
Six elements on the periodic table account for 97 percent of your body’s mass:
carbon, hydrogen, nitrogen, oxygen, sulfur and phosphorus

About 85% of the body’s phosphorus is in
bones and teeth
. Phosphorous is also present in smaller amounts in cells and tissues throughout the body. Phosphorus helps filter out waste in the kidneys and plays an essential role in how the body stores and uses energy. It also helps reduce muscle pain after a workout.
Carbon
is the second most abundant element in the human body, accounting for 18% of body weight.
The six most common elements of life on Earth (including more than 97% of the mass of a human body) are
carbon, hydrogen, nitrogen, oxygen, sulphur and phosphorus
.
A normal level of oxygen is usually
95% or higher
. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood. If your home SpO2 reading is lower than 95%, call your health care provider.
The human body is a single structure but it is made up of billions of smaller structures of four major kinds:
cells, tissues, organs, and systems
. An organ is an organization of several different kinds of tissues so arranged that together they can perform a special function.
An adult human body weighing 70 kg contains about 0.2 milligrams of gold
. It’s been found that the element plays an important health function, helping to maintain our joints, as well as facilitating the transmittal of electrical signals throughout the body.
Cucumber,

water
Cucumbers are made up of around 96% water – that’s the highest water content of any food. They’re also low in calories, and a source of vitamins and fibre.
