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
