===Meaning===
[[Lipid]]s are [[molecule]]s, made of a [[glycerol]] head and 3 [[Fatty Acid|fatty acid]] tails, that is are found in fats and oils.
===About Lipids===
: [[Lipid]]s are an essential [[nutrient]] in our [[diet]] that is used in our [[Nervous System|nervous system]].
: [[Lipid]]s store [[Chemical Potential Energy Store|chemical energy]] at a higher [[energy]] density than [[carbohydrate]]s so the body stores extra [[energy]] in [[Fatty Tissue|fatty tissue]] made of [[lipid]]s.
: If there are too much many [[lipid]]s in our [[diet]] then we can become [[Obesity|obese]].: [[Lipid]]s are broken down by our [[Digestive System|digestive system]] into a [[glycerol]] head and 3 [[Fatty Acid|fatty acidacids]] tails.: The [[Fatty Acid|fatty acids]] in [[lipid]]s can be many different lengthsbut the [[glycerol]] head is the same for all [[lipid]]s.

| style="height:20px; width:125px; text-align:center;" |Butter is full of fat and we shouldn't eat too much. Butter is found in cakes and cookies.
| style="height:20px; width:125px; text-align:center;" |Cooking oil is used to fry our food causing it to have a lot of oil inside it. A small amount is healthy but too much is bad for us.
