What are polymers? | Proteins |
What are some characteristics of Saturated lipids? | Single bonds only Each carbon is saturated with a hydrogen atom Solid at room temp Leads to cholesterol issues |
What are some examples of Saturated lipids? | Butter Ice cream Steak Trans animal fats from hydrogenation |
What are some characteristics of unsaturated lipids? | Double/triple bonds Have C-C mixed with C-H bonds Molecule is bent Liquid at room temp Monosaturated fats and lowers bad cholesterol and raises good cholesterol |
In carbon atoms which fatty acids can be bonded with more hydrogen atoms? | Unsaturated fatty acids |
What are some characteristics of phospholipids? | Has two fatty acids attached to the glycerol In the cell membrane |
