Lipids and protein

Question 1

What is the main function of fat In humans

Answer 1

Energy storage

Question 2

Why are fats insoluble

Answer 2

Because they hydrophobic and non polar

Question 3

What molecule is formed when a glycerol molecule bonds with a 3 fatty acid chains to make a triglyceride

Answer 3

H20 is formed and it’s a condensation reaction

Question 4

What is structural diff between triglyceride, a glycerol and a fatty acid

Answer 4

Glycerol is the spine of the tryglyceride and fatty acid is a chain that connects OH with glycerol to form water and becomes triglyceride

Question 5

Do we need cholesterol even tho it causes health problems

Answer 5

Yes we need a little bit because Your body needs cholesterol makes hormones and builds cells

Question 6

what are some examples of lipids found in organisms

Answer 6

fats, oils, waxes, cholesterol

Question 7

what is triglyceride

Answer 7

are long term energy storage that contain a glycerol and 3 fatty acid chains

Question 8

what is diff between unsaturated fats and saturated fats and which ones are better for you

Answer 8

unsaturated fats have one or more double bond causing it to be liquid at room temp while saturated fats have only single bonds causing them to be solid at room temperature.

unsaturated fats are better for health

Question 9

what are cis and trans fatty acids and which one is better for you

Answer 9

cis fatty acid, the acid will contain double bonds that are formed by hydrogen atoms. The trans-fatty acids will contain double bonds that are formed by carbon atoms.

Trans fats are bad for you

Question 10

what does hydrogenating mean

Answer 10

it is how trans fats are made- by partially hydrogenating unsaturated fats.

The addition of hydrogen to a compound, especially to solidify an unsaturated fat or fatty acid.

Question 11

what is the monomer of protein

Answer 11

amino acids

Question 12

what are amino acids made out of

Answer 12

carboxyl and amino group

Question 13

Amino acids are linked together by

Answer 13

peptide bonds

Question 14

proteins are made from ___________ as these _____ forms they develop multiple structures such as ____________________

Answer 14

proteins are made from long chains of amino acids and as these chains develop they become structures such as primary, secondary, tertiary, quaternary

Question 15

The overall shape of a poly peptide is in what structure

Answer 15

tertiary which is made when the secondary folds and twists upon itself, once polypeptides have made a tertiary structure, they are referred to as proteins

(don’t understand why)

Question 16

quaternary structures are what

Answer 16

the mixing and interactions between multiple proteins like the tertiary structure

Question 17

what is an ex of a quaternary structure

Answer 17

hemoglobin

Question 18

how is a dipeptide formed

Answer 18

when 2 amino acids bond together and condensation occurs and the bond between is peptide

Question 19

what is a peptide bond

Answer 19

when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).

Question 20

what is a protein made out of

Answer 20

polypeptide chains of amino acids

Question 21

genes which are made out of DNA determine the number and number of amino acid, true or false?

Answer 21

true

Question 22

what do each amino acids have

Answer 22

carboxyl group, amino group with the R group

Question 23

what is the folding called of the secondary structure

Answer 23

alpha helix or beta pleated sheet

Question 24

Can the R group differ in amino acids and change it completley?

Answer 24

yeah

Question 25

what is a quaternary structure

Answer 25

a Protein consisting of more than one polypeptide chain of amino acids

Question 26

when a protein is in a too hot or too cold place than it wants to be what happens or ph lvl is too hot or to high what happens

Answer 26

Thinking deeper…. you know enzymes are proteins therefore denaturing happens
