LIPIDS

A group of organic compounds that are insoluble in water but soluble in organic solvents, commonly known as fats.

New cards
2

Triglycerides

A type of lipid made from glycerol and three fatty acid chains, serving as a major form of energy storage in the body.

New cards
3

Sterols

A class of lipids essential for cell membrane structure; cholesterol is the most well-known sterol.

New cards
4

Saturated Fatty Acids

Fatty acids with no double bonds between carbon atoms, solid at room temperature, found in foods like butter and cheese.

New cards
5

Unsaturated Fatty Acids

Fatty acids that contain one or more double bonds, liquid at room temperature, typically found in plant oils.

New cards
6

Monounsaturated Fatty Acids

Fatty acids with one double bond, associated with lower LDL cholesterol levels and found in olive oil and avocados.

New cards
7

Polyunsaturated Fatty Acids

Fatty acids with multiple double bonds, can lower LDL cholesterol and increase HDL levels, includes omega-3 and omega-6 fatty acids.

New cards
8

Omega-3 Fatty Acids

Essential fatty acids found in fish and flaxseeds, important for heart health and reducing inflammation.

New cards
9

Omega-6 Fatty Acids

Essential fatty acids found in various oils, necessary for growth and maintenance of healthy bones.

New cards
10

Cholesterol

A waxy, hydrophobic substance that is an essential component of cell membranes and a precursor for steroid hormones.

New cards
11

Low-Density Lipoproteins (LDLs)

Known as 'bad' cholesterol, which can lead to plaque buildup in arteries, increasing heart disease risk.

New cards
12

High-Density Lipoproteins (HDLs)

Known as 'good' cholesterol, which helps transport cholesterol away from the arteries and to the liver for processing.

New cards
13

Trans Fats

Unsaturated fats that have been hydrogenated to become solid, commonly found in processed foods; associated with negative health outcomes.

New cards
14

Visceral Fat

Fat that surrounds vital organs, which can be harmful in excess and associated with chronic diseases.

New cards
15

Adipose Tissue

Body fat stored in fat cells, which plays a role in energy storage and insulation.

New cards
16

Hydrogenation

The process of adding hydrogen to unsaturated fats to make them solid; often used to create trans fats.

New cards
17

Cholesterol Sources

Primarily found in animal products like meat, cheese, and eggs.

New cards
18

Dietary Fibre

Non-digestible carbohydrates that help reduce cholesterol absorption in the bloodstream.
