Water (H2O)
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.
Water is the most abundant substance in the human body, making up about 60% of an adult's body weight. It plays a crucial role in many bodily functions, including temperature regulation, nutrient transport, and waste removal.
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.
It is the most abundant element in the body.

Water is the single most abundant chemical substance in the body, making up about 60% of an adult's total body weight.
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.
This substance is water, H2O.
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".
Water is the most common molecular subsance found in the human body(~98%). and phosphorous is the most abundant element in human body.

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.
Protein.
