Why carbon is important: make up all compounds

• They are versatile
• They can form bonds base on (sp)
• They can combine with 4 atoms
• They can combine with themselves and form chains which are called hydrocarbons
• can also add henchonal group and replace hydrogen
• hydrocarbon chains are long, they can form ungs and some can form chains of rings

C. LIPIDS

1. “Hydrophobic” Substances

• lipids hate water because they have covalent non polar bonds  

• water love itself because its a potatized covalent bond So it is hydrophilic
• Almost all lipids are hydrophobic
• Not every hydrophobic molecules are lipids

1. Functions:

• Energy Storage: lipids are the best energy storage because they have twice as more volume than other macromolecules (all macromolecules store energy)
• Heat Insulators: heat is potential energy. All organisme wants to maintain stable body temperature  So that chemical reactions can occur
• Lubricants lipids can act as lubricant in joints & all kinds of movement
• membranes all cells are of lipids have membranes
• Lipids are less dense than water, they float in water (Buoyancy)

1. Triglycerides[have nothing to do with water ]

1. glycerol three carbon attach to alcohol
2. Fatty Acids :

 All fat are lipids but not all lipids are fat If you want to learn more check out What are the characteristics of Medieval Europe?

i. saturated: carbon is bound to the maximum atom.

    it can be bound to -C- Don't forget about the age old question of Who was the first legendary dynasty of rulers that laid a foundation to all Chinese traditions?

   (when carbon is bound to 4 atoms it is saturated)

ii. Unsaturated: when carbon is not bound to the maximum atom it can beIf you want to learn more check out bad debt writeoff

bound to because there's double or triple bond

Don't forget about the age old question of Why do eukaryotes contain internal membranes?

• Saturated causes block artery problem
• Saturated fat is less health than Unsaturated
• Because the double bonds can be broken down so unsaturated can turn to saturated.

We also discuss several other topics like Which culture did that Baal Cycle come from?

1. Phospholipids:  have 60th polar and nonpolar

Characteristics.

1. head - hydrophilic
2. tails - hydrophobic

1. micelles: when you put amoniphites in water

Structures that have polar bonds on one end and none-polar on the other (amphiphilic)

1. Phospholipid bilayer
2. Cell membrane have cholesterol
3. waxes: hydrophobic / so it's a lipid
4. Hormones in a

All sterols comes from cholesterol

• not all chorestents are bad
• cholesterol must be delivered to the entire body, it hates blood
• Proteins helps to transport cholesterol
• low density protein is HDL
• HDL - good type of cholesterol
• LDL - bad type of cholesterol
• high level of LDL can cause Arteriosclerosis
• All cell membranes must have cholesterol
• cholesterol helps in fighting bacteria
• cholesterol helps in fat digestion
• vitamin D: cholesterol can be turned into vitamin D
• Menstruation: cholesterol derived hormones

D. Proteins

• long chains of Amino acids
• All amino acids have amine groups & carboxyl groups
• peptide: bond form b/w amino acid. Water must be removed to form peptides bonds
• Dipeptide: in a dipeptide there's one pephills bond
• pepsin:rare enzyme that doesn't end "ase”
• Produce in our stomach.
• pH (2) for pepsin

Functions: based on its 3 - Dimension structures

• Energy reserves as the last one carbohydrates & lipids come first
• Almost all enzymes are proteins (enzymes)
• HDL and LDL can transport lipids (transport)
• Contractile (muscles)
• Receptors (receive a structure and can tell whether it is the part of the individual)
• Defensive: antibodies are proteins

Protein 3- Dimension Structure

• Primary structure - strength line
