Biology 3 Flashcards
Carbohydrates includes
Glycogen (animal) and starches (corn, wheat)
Glycogen
Branched structure
Starch
Straight rigid structure
Glycogen is made of
Glucose (monosaccharide)
Lipids includes
Fats, oils, and cholesterol
Lipids function
Cell structure (cell membrane) and stored energy
Two types of lipids
Triglycerides and phospholipid
Triglyceride is
Glycerol and 3 fatty acid tails
Saturated fatty acid
Fully saturated with hydrogen ions. All single bonds between carbs
Unsaturated fatty acid
Not fully saturated with hydrogen ions. At least 1 double bond
Phospholipid composed of
Phosphate, glycerol, 2 fatty acid tails
Phospholipid head
Polar and hydrophilic
Phospholipid tail
Nonpolar hydrophobic
Amino acid groups
Amino group and carboxyl group
The only thing that changes from amino to amino
“R” group
The process of _ links amino acids together
Condensation
_ different amino acids
20
Nitrogen bases
Adenine, thymine and cytosine, guanine
Nucleotide
Sugar, phosphate, and base
Only thing that changes when comparing DNA nucleotides
Nitrogen base
Polymer= DNA
Double stranded, deoxytribose sugar, A T C G for bases, cannot leave nucleus
RNA
Single stranded, ribrise sugar (smaller), A UCG, can leave nucleus
3 types of RNA
rRNA= ribosomal RNA
mRNA= messenger RNA
tRNA= transfer RNA
Sugars and phosphates are
Covalently bonded
Nitrogen bases are held to get her with
Hydrogen bonds (weak)
