Functions of Protein
Structual support, communication, membrane transport, catalysis, protection and recognition, movement, cellular adhesion
Steroids
Cholesterol is the major steroid - makes tesosterone, bile acids, progesterone, estrogens, cortisol
Types of Lipids
Fatty acid, triglycerides, phospholipids, steroids, eicosanoids
Phospholipids
you have phosphorus and nitrogen attached throughout the structure - 2 regions hydrophilic and hydrophobic
Another word for Phospholipids
Amphiphilic - the head and two tails give the shape of a clothespin
Phospholipids function
Main function to serve as the structural foundation of cell membranes
Primary structure of Protein
protein is a chain of substance that make protein amino acids - are the building block
Secondary structure of Protein
when you start putting chains of protein together and you combine the chains using hydrogen bonds
Teritiary Structure of Protein
folding and bending of secondary structure
Quaternary Structure of Protein
2 or more of the proteins chains stuck together
Organic
consist of carbon
Inorganic
water and carbon dioxide, bicarbonate ions, carbon monoxide
ATP
your energy - used very quickly - anaerobic 2 and aerobic respiration 36 to 38
Triglycerides
molecule consisting of 3 fatty acids tails combine to a glycerol backbone - primary function is energy although provides thermal insulation from cold, shock absorber for organs
Eicosanoids
prostaglandins are hormone messangers - play role in inflammation, blood clotting, hormone action, labor, and contractions
Denaturation
when you go from a highly folded protein and you add heat to it - ex. when you cook an egg
Enzymes
they break down and are a type of protein
Hemoglobin molecule
consist of 4 polypeptides chains - 2 identical alpha chains and 2 identical longer beta chains
Structure of ATP
Adenine - Ribose - 3 phosphate groups
Disaccharides
are sugars composed of 2 monosaccharides sucrose, lactose and maltose
Sucrose
Table sugar
Lactose contains
glucose and galactose
Maltose contains
glucose and glucose
Sucrose contains
glucose and fructose
Carbohydrates
are hydrophilic - monosaccharides - glucose, fructose, galactose
Carbohydrates are stored
in liver and skeletal muscles
Polysaccharides
glucose molecules stuck together to form long chains of glucose
Polysaccharides contains
glycogen, starch and cellulose
Starch and Cellulose
Plant products
Glucose importance
to make energy and ATP
Fatty Acid
chain of usually 4 to 24 carbon atoms
