Every fatty acids has a long hydrocarbon chain (with even amounts of carbons, usually 16 or 18) and a carboxyl group.
glycerol is a 3-carbon molecule with 3 -OH groups.
fatty accids and glycerol can be connected by single or double bonds, depending on if the fatty acid is saturated or unsaturated.
when a lipid forms, the -COOH functional groups of 3 fatty acids react with -OH groups of glycerol.
this leaves 16, 18, or 20 carbons, making a triglyceride 16, 18, or 20 carbons long.
hope this helps!
Answer:
Original Remains Fossil
Explanation:
Fossils that are the actual bodies or body parts of organisms are called original remains fossils. A Mold fossil is a fossil formed when complex parts of an organism are trapped in sediment dissolved away leaving behind a hollow area with the organism's shape. A cast fossil is a fossil formed when sediment fills in the hollow space of the shape of an organism. A carbonized fossil is a fossil when a dead organism is compressed over time and the pressure drives out the liquids and gases leaving behind an outline of the organism
