Indicate whether each of the following statements about triglycerides is true or false.
Indicate whether each of the following statements about triglycerides is true or false.
1. A triacylglycerol is composed of 3 glycerol molecules joined to a fatty acid.
2. The hydrocarbon chains of fatty acids vary in length as well as in the number and location of double bonds between the carbon atoms.
3. Fatty acids with one double bond in their hydrocarbon chain are called monounsaturated, while those with more than one double bond are called polyunsaturated.
4. Additional hydrogen atoms can be added to saturated fats, a process called hydrogenation.
5. When unsaturated fats are partially hydrogenated industrially, this can produce trans fats which have been linked to elevated levels of low-density lipoprotein (LDL) “bad cholesterol” and lowered levels of high-density lipoprotein (HDL) “good cholesterol.” references primary, secondary, tertiary and quaternary structures
Primary
Secondary
Tertiary
Quaternary
The sequence of amino acids in the polypeptide chain
Alpha helix
The overall 3-D shape of a polypeptide or protein
The way several different polypeptide chains fit together to form the final protein
Ala-gly-tyr-lys-met-trp-phe
Beta-pleated sheet
Results from the bending and folding of a polypeptide chain that occurs due to a variety of interactions b/w the amino acid side chains
Only found in proteins composed of more than one polypeptide chain
Results from hydrogen bonds b/w polar groups in the polypeptide backbone
Repeated pattern of coiling or folding w/in a polypeptide chain
Q7: additional hydrogen atoms can be added to saturated fats, a process called hydrogenation-FALSE
Endoplasmic reticulum: Endoplasmic = within the cytoplasm, reticulum = “little net”
Atoms:
Nucleus= protons (+) and neutrons ( )
Surrounding nucleus = electrons (-)
Ions: unequal number of protons and electrons -Cation = more protons than electrons (+ charge) -Anion = more electrons
