The human body is made up mostly of water.
Water is the most abundant substance in the human body, making up approximately 60% of our total body weight.
The most abundant chemical substance in the human body is water. There are a lot of H2O molecules throughout the human body.
The second most abundant substance in the human body is proteins. Proteins are essential for various functions in the body, including building and repairing tissues, supporting the immune system, and serving as enzymes and hormones.
Proteins are the second most abundant substance in the human body and are essential for the structure, function, and regulation of all cells. They play a critical role in various biological processes such as growth, repair, and immunity.
Water would be the most abundant substance but if you're asking about elements then oxygen would make up the greatest percentage of body mass.
Water is the most abundant substance in the human body, making up approximately 60% of our total body weight.
The most abundant chemical substance in the human body is water. There are a lot of H2O molecules throughout the human body.
Water is the single most abundant chemical substance in the body, making up about 60% of an adult's total body weight.
This substance is water, H2O.
The second most abundant substance in the human body is proteins. Proteins are essential for various functions in the body, including building and repairing tissues, supporting the immune system, and serving as enzymes and hormones.
carbon
The question is flawed. Substance can mean element or molecule. I'll go with molecule since organic simply means carbon atoms are present. Hydrogen dioxide is the most abundant inorganic "substance".
Proteins are the second most abundant substance in the human body and are essential for the structure, function, and regulation of all cells. They play a critical role in various biological processes such as growth, repair, and immunity.
Protein.
Water is the most common molecular subsance found in the human body(~98%). and phosphorous is the most abundant element in human body.
Solvent
The most abundant substance in the cytoplasm of cells is water, by a good margin. The most abundant organelle [cellular organ] by mass are ribosomes, which convert DNA into protein.
