saponifiafiable of lipid examples
waxes triacyglycerole triglycerides
nonsaponifiable lipid
no OH BOND NO ESTER STEROID TERENE no fatty acid
lipids function
structural components cell membranes chemical messagerrs insulation protective coating shock absorbers storage and transport fuel
saturated fatty acids
PSS PAMISTIC STEARIC SATURATED
unsaturated fatty acid
oleic acid Linoleic acid
fatty acid are
long branch hydrocarbons with carboxl group
lipid functional group
ester
triacygylcerol make up most lipid in our food
true
tryacylglycerol
3OH +Gylcerol +3fatty acid 3 esters
hydrogenation
alkene +H2 >Alkane break double bond , you add H’s can also form alcohol
fluid mosaic model describes the plasma membrane of all cells with cis double bond carbohydrates cholesterol selective permeability
true
protein are held by
amide bond
function of protein (build stuff in body
stuctural collagen keratin ( hair skin ) enzyme catalysts hormones regulate metabolism and nervous system protection - immunoglobulin (antibodies transport hemoglobin storage - myoglobin regulation - gene expression
type of proteins
fibrous insoluble in water provide structure of cell globular compact- spherical shape -soluble transport protein
amino acid are neurotransmitters?
yes
glycine
G NONPOLAR Has H (side) achiral
alanine
nonpolar CH3 ( G side) A
cysteine
polar - neutral HS - CH2 C
glutamic acid
acidic - Polar E O—C=O-ch2ch2 (ch2)COOH
lysine
lys K Basic polar (Ch2)4NH2
what is a zwitteriom
A molecule that has both positive and a negative charge, but we remain electrically neutral overall act as buffer
only L AMINO ACID OCCUR IN PROTEIN
true
which amino acid has chiral except one
all amino acid have chiral except glycine who only H
