Abeka Biology God's Living Creation Fourth Edition: Chapter 9.1

The chemical processes that occur within a living organism in order to maintain life

The measurement used in the energy content of food

Fat cells that are used in excess energy-producing substances

Being severely overweight due to excess body fat

A group of nutrients that are needed in relatively large amounts. This is your body's primary source of energy and building materials. 

- Carbohydrates- Protein - Fats

Most important energy-producing compounds in cells. Provide most of the energy for living things. Includes sugar, glucose.

Monosaccharides and disaccharides

Polysaccharides

Mixture of polysaccharides manufactured by plant cells for glucose storage

- Soluble fiber: Turns into a gel during digestion, slowing digestion and helping the stomach and intestines absorb nutrients.

- Insoluble fiber: Helps move undigested wastes along to keep the intestines clean and healthy.

Half of the body's dry weight is composed of this complex organic molecules that is used to build and maintain living cells. It is made of simpler molecules called amino acids.

Fats, oils, and fatlike substances; a varied group of compounds characterized by their insolubility (inability to dissolve) in water. Used by the body primarily to store energy and to build cell parts. All cell membranes are built mainly by it.

The simplest type of lipid molecule. A molecule made of carbon and oxygen atoms attached to a long chain of carbon and hydrogen atoms.

Are 3 fatty acid molecules attached to a single molecule.

Fats that are liquid at room temperature
