Waxes, triacylglycerols, and phospholipids are categorized as:

Steroids, fat-soluble vitamins, and eicosanoids are examples of:

These are esters of fatty acids with various alcohols.

Simple lipids contain one of each of these two:

This simple lipid is formed from glycerol and three molecules of fatty acids.

These lipids are derived from fatty acids.

This fatty acids contain only single bonds.

This fatty acid contains at least one double bond.

This unsaturated fatty acid contains one double bond.

This unsaturated fatty acid contains two or more double bonds.

TRUE OR FALSE: When the number of double bonds in the fatty acid increases, the melting point decreases.

SATURATED OR UNSATURATED: stearic acid

SATURATED OR UNSATURATED: oleic acid

SATURATED OR UNSATURATED: linoleic acid

SATURATED OR UNSATURATED: palmitic acid

These fatty acids are generally found in nature.

These fatty acids are rare and manufactured.

Trans fatty acids are created during this process involving polyunsaturated fatty acids.

CIS OR TRANS: Fatty acids that have two hydrogen atoms on the same side of the double bond.

CIS OR TRANS: Fatty acids with a kink in its structure.

CIS OR TRANS: fatty acids that have two hydrogen atoms on the opposite side of the double bond.

These are fatty acids that cannot be produced by the body.

The parent fatty acid of the omega-3 family.

These are fatty acids synthesized from ALA.

The parent fatty acid of the omega-6 family.

This is a structural fat found throughout the body and is most abundant in the brain, eyes and heart.

This fatty acid is necessary for the growth of infants, hence found in breast milk.

This helps with childhood behavior and academic performance, and lowers risk of cognitive decline and dementia.

Humans store energy in adipose cells through this form.

A mixture of triglycerides containing a high proportion of long-chain, saturated fatty acids.

A mixture of triglycerides containing a high proportion of long-chain, unsaturated fatty acids, or short-chain, saturated fatty acids.

FAT OR OIL: obtained from animals

FAT OR OIL: solid at room temperature

FAT OR OIL: have higher melting points

FAT OR OIL: colorless and bland in taste

FAT OR OIL: lower melting points

FAT OR OIL: liquid at room temperature

FAT OR OIL: obtained from plants

FAT OR OIL: undergoes saponification when hydrolysed

This is the process for fats’ when turning spoilt.

This is a condition caused by fat oxidation, when peroxides are formed from the reaction of polyunsaturated fatty acids with oxygen.

This is a condition caused by fat hydrolysis, developed through hydrolysis of triglycerides where free fatty acids are released.

They are extremely hydrophobic because of their long nonpolar C chains and form protective coating on plants, fruits, and animals.

These are lipids that contain parts other than just fatty acids and alcohol.

These are long chained fatty acids on a glycerol backbone attached to a phosphoric acid molecule containing an alcohol substituent or amino alcohol.

These are important components of the cell membrane which easily form micelles.

They are found in most cell membranes and aid in blood clotting.

These are complex lipids built from long chained fatty acids attached to a sphingosine backbone rather than glycerol.

This sphingolipid is found in the myelin sheath surrounding nerve cells (structure phosphoric acid + choline).

These sphingolipids are often called cerebrosides because of their abundance in brain tissue (structure carbohydrates).

They define human blood groups.

Blood type that contains antigen A on rbc and anti-B antibody on plasma.

This complex lipid is the primary means of transport of cholesterol among tissues.

Lipoproteins are secreted by these organs into the circulating blood.

Along with lipids, lipoproteins are composed of these special proteins called ______.

This lipoprotein is formed in the mucosal cell of the intestine.

This lipoprotein is formed in the liver for the export of triglycerides.

This lipoprotein is a primary carrier of cholesterol in the blood for delivery to the tissues.

This lipoprotein is the scavenger for cholesterol from peripheral tissues, returning it to the liver for metabolism.

These lipids are the products of the hydrolysis of simple and complex lipids.

These are a group of lipids whose carbon skeletons contain several fused rings.

This is the most prominent steroid.

Also known as steroid alcohol.

Other name for plant sterols.

This lipoproyein deposit cholesterol on the walls of arteries forming a plaque and restricting blood flow.

This lipoprotein reduce cholesterol levels in the bloodstream.

This is the consequence of excess LDL in the blood.

This is composed of fat, cholesterol, calcium and other substances found in the blood, limiting the flow of oxygen-rich blood and increased risk of blood flow.

They are polarized steroids that play a vital role in intestinal fat absorption
