Saturated fatty acids are long hydrocarbon chains with a carboxyl group (-COOH) at one end. They consist of carbon atoms bonded to each other by single bonds, and each carbon atom is saturated with hydrogen atoms. This gives them a straight and rigid structure.
Physical State: Saturated fatty acids are usually solid at room temperature. This is because the straight structure of saturated fatty acids allows them to pack closely together, resulting in stronger intermolecular forces and higher melting points compared to unsaturated fatty acids.
Dietary Sources: Saturated fatty acids are commonly found in animal-based products such as meat, poultry, dairy products, and butter. They can also be found in some plant-based sources like coconut oil and palm oil.
Health Implications: Consuming excessive amounts of saturated fatty acids has been associated with an increased risk of cardiovascular diseases. This is because saturated fats can raise levels of LDL cholesterol (commonly referred to as "bad" cholesterol) in the blood.

C. Polysacchaides
D. Amino Acids
Answer:
A. Ketones
Explanation:
I took the test and 'Amino Acids' was incorrect. Ketones are formed from the breakdown of the tissue and are released into the bloodstream, also known as ketonemia.
