what are the three examples of lipids and their uses | fats, energy storage...phospholipids, form cell membrane and other structures...steroids, form hormones, bile |
fats,phospholipids,steroids what do they do | energy storage...form cell membrane and other structures...form hormones, bile |
what does a triglyceride monomers contain | glycerol and 3 fatty acids |
all single bonds b/w C atoms- fully filled with H is | saturated |
one or more double bonds b/w C atoms- spaces for more H | unsaturated |
what is a better energy source for the body | carbs |
elements in a protein | c,h,o,n and sometimes s |
uses in a protein in the body | structures, hormones, enzymes, antibodies, energy |
monomers of proteins | amino acids |
components of an amino acid | amino acid, carboxyl group, side chain |
how many diff amino acids exist | 20 |
what creates the various diff proteins | different R groups |
3 dimenstional shape caused by different amino acids | native conformation |
shape changes or falls apart due to heating, beating, freezing, electricity,ph | denaturation |
elements in nucleic acids | c,h,o,p,n |
monomers of nucleic acids | nucelotides |
nucleotides are made up of | sugar, phosphates, nitrogenous base |
store info to make up proteins, pass on info to daughter cells?? | functions of deoxyribonucleic |
function of ribonucleic acid | copy info to make proteins |
synthesisrxns- building molecules | anabolism |
dehydration happens in what | anabolism |
as bond is formed h2o is released | dehydration synthesis |
breakdown molecules | catabolism |
consumes water in what | catabolism |
what is broken down to split a larger molecule | hydrolysis |
proteins that spend the rate of chemical reactions, they are biological catalysts | enzymes |
the molecule that a particular enzyme acts upon | substrate |
pockets on the enzyme where the substrate attaches | active site |
inorganic enzyme activator | cofactor |
organic enzyme activator | coenzyme |
a chemical from the enviroment needed by the body | nutrient |
body needs a large amount- carbs, lipids, proteins | macronutrients |
body needs small amounts- vitamins, minerals | micronutrients |
the amount of heat needed to raise the temputure of water, and cal or kcal = | calorie, 1000cals |
carbohydrates uses in the body | immediate energy, short term energy storage, building some cell structures |
broken into monosaccharides | digestion |
