Omega-6 fatty acid | margarine made from corn or safflower oil |
Highest amount of saturated fat | butter |
Hydrogenation | The process of adding hydrogen to an unsaturated fatty acid and creating a more solid fat |
Health problem assocaited with high intakes of fat replacers | gastrointestinal distress |
triglyceride is comprised of | 3 fatty acids and 1 glycerol |
Excellent source of unsaturated fat | nut and nut butters |
Sterols | A sex hormone and adrenal hormone are substances derived form this lipid |
225 kilocalories | are potentially provided by 25 grams of fat |
Olive oil and cashew nuts | rich sources of monounsaturated fatty acid |
A key structural componant of a cells membrane | phospholipids |
These organs assist in the digestion of lipids | liver, gallbladdar, and pancreas |
Major classes of dietary lipids | triglycerides, sterols, and phospholipids |
fatty acid that contains a chain of ten carbons and one double bond is termed a fatty acid | monosaturated, medium chain |
function of fat in the human body | fats assist transport of fat-soluble vitamins, maintains integridy of cell membranes and provides insuation to help retain body heat |
Saturated Fat | Solid at room tempurature |
Two essential fatty acids | alpha-linolenic and linolenic |
the vast majority of fat digestion and absorption occurs in | small intestine |
to facilitate the digestions of dietary fats, the gallbladder stores and releases a substance known as this | biile |
Majority of triglycerides are stored here for future energy needs | adipose tissue |
Saturated fats are | found in whole milk and beef |
researchers found the strong association with dietary fat intake and | prostate cancer |
major form of fat in both food and body | triglycerides |
Fatty acids | created during the hydogenation process |
chylomicron | a lipoprotein transports dietary fat out of the small intestines |
medium chain fattty acids are | 6-12 carbon atoms in length |
Fructose and glucose, bonded together form | table sugar |
insoluble fiber consumption is associated with | decreased blood cholesterol levels |
Preferred fuels for most body functions | carbohydrates and fats |
Carbohydrates contain | carbon, hydrogen and oxygen |
hormone released when blood sugar is too high | insulin |
Complex carbohydrates refer to | polysaccarides |
disaccharide is formed by chemical bonding of | two monosacharides |
pectins | an example of a soluble fiber |
(RDA) od carbohydrates for an adult | 130 grams |
a technique by athletes to increase their storage of muscle glycogen | carbohydrate loading |
glycemic index | extent to which a given food raises blood glucose and insulin |
insulin | hormone responsible for moving glucose into the bodys cells after a meal |
this carbohydrate is the end product of photosynthesis | glucose |
Fructose | known as levulose |
insulin is synthesized and released by this | pancreas |
Cellulose | insoluble fiber that provides the main structural component of plant cell wall |
saccharine | artificaial sweetmer that was almost banned because of relationship with bladder cancer |
glucose | major monosaccaride found in the body |
enrichd food | nutrients in the food were lost during the process and then added back in |
a lower fiber diet is associated with an increased risk of developing | diverticulosis |
liver and muscles | major storage sites for glycogen |
glycogen | the storage form of glucose in animals found in the liver and skeletal muscle |
The process through which mRNA copies genetic information from DNA and carries it to the ribisome | transcription |
proteins differ from carbs because | proteins cintain nitogen |
this strucure refers to the twisting, spiral shape formed by the sequence and chemical properties of its amino acids | proteins secondary structure |
most protein from this plannt source | soybean |
major functions of protein in the human body | maintaining fluid balance, growth and maintenence of new tissue and synthesis of hormones |
egg whites stiffen when they are whipped, this change that occurs in the protein is called | denaturation |
part of amino acid molecule | central carbon, amine group, and an acid group |
amine group | protein molecule that carries nitrogen |
dictates the structure of a protein molecule synthesized by the body | DNA inside the nucleus of the cell |
conduction of nerve signals and contraction of muscles depends on the proper balance of | electrolytes |
polypeptides | string of more than 10 amino acids |
mutual supplementation | process of combining two incomplete proteins to make a complete protein |
protein thats fundamental to the nervous system | antibodies |
translation | the process of protein synthesis which the messenger RNA is decoded into an amino acid sequence at the cells ribosome |
nitrogen | is what differs protein different from fat |
significant chemical digestion of protein begins in | stomach |
struture of the mammalian cell are proteins synthesized | ribosome |
source of complete protein | chicken |
a complete protein contains | all 9 amino acids |
absorption of proteins occurs | small intestine |
